    Heavy Snowfall
    December 8 - 9, 2017
     
    Event Summary Snow Accumulation Map Recorded Snowfall Totals Event Photos   Event Summary A major early-season heavy snowfall affected north Georgia from Friday, December 8th into the morning of Saturday, December 9th. Many locations recorded up to a foot of snowfall, which is exceptionally rare for Georgia, especially in early December! This heavy snowfall also led to numerous power outages. At the height of the storm over 200,000 customers in north Georgia were in the dark. There was a sharp northwest to southeast gradient of accumulating snow through metro Atlanta. Areas southeast of Atlanta did not receive much accumulating snow, while areas north and west of the city received very significant totals.   Snow Accumulation Map:

    Above: The heaviest snow accumulations occurred in a ribbon stretching from Carroll County into the northwestern Atlanta suburbs and into the north Georgia mountains. Up to a foot of snow accumulated in these areas!

    First Autocross

    By NorthGeorgiaWX,


    Car
    Well... I don't think that turned out too bad for the first time out in three years. I haven't seen the final results yet, but the car felt really good and I wasn't as rusty as I thought I was going to be. 🙂

    It was a great day for an autocross with partly cloudy skies and warm temperatures, but as the day went on the clouds filled in and the winds picked up, and we had a few sprinkles for the last heat but nothing to really slow anyone down. There were only 51 entries so everyone got 8 runs (I got 9 because of a rerun due to a timing error). The course was about 0.70 miles long and took about one minute to drive. I really liked the course except for the slaloms as those were brutally tight. 15 paces is not enough between cones, you need 20-25 to maintain some sibilance of speed. There was also a Chicago Box that was equally as brutal and almost required a full stop to navigate. All of that was in stark contrast to the rest of the course which was relatively open and flowed nicely. Those really tight features are not something you see on a well designed autocross course. 
    Today I tried some different traction control settings, tried shifting manually and also letting the trans do it's thing on it's own, so basically a big day of experimenting. I didn't mess with tire pressures much and probably should have, but I was more focused on shaking off the rust and just trying to get a feel for the car. 🙂 I noticed on the way back home, I was down on boost and I suspect I have air in the intercooler which will need to be bled. I'm not sure when it started happening but it is a noticeable loss in power when the boost drops from 18-19 psi to 12-14 psi and you loose 100 whp. I'm not sure how many runs I made with low boost, so I don't know if or how much that may have slowed me down, but I suspect a decent amount.
    I was in the first run group which was the best driving weather, so that was good. 

     
    So here are some of the runs, I missed starting the PDR on runs 2-3-4 so missed those completely. My GoPro died before I could get a video. It locked up so I pulled the battery to kill it. After that, the red charging light comes on but the camera doesn't, so I was very disappointed that I couldn't get any videos from that camera. The in-car camera is only 720p while the GoPro is 1080p. I'll get it figured out before the next event or get a new camera. 
     
    Run 1
     
     
    Run 1 Rerun
     
     
    Run 2 or 3... take your pick
     
     
    Run 6
     
     
    Run 7
     
     
    Run 8
     
     
    Results are posted. I'll take it. I think had I not lost boost midway through I could have dropped another second or so. Next time I'll work on tire pressures and make sure I have the car in something other than Sport 1 mode.

    Hurricane Michael

    By NorthGeorgiaWX,

    All data from the Atlanta NWS office
    Hurricane Michael Hits Georgia
     October 10, 2018
    [Overview]
    [Damaging Wind]
    [Wind Damage Photos]
    [Heavy Rainfall]
    [Tornadoes]

     
    Overview:
    Hurricane Michael made landfall along the Florida panhandle near Panama City on the afternoon of October 10, 2018 as a high-end Category 4 hurricane. Michael then moved rapidly inland, causing widespread wind damage along its path. Hurricane Michael was the strongest hurricane on record to make landfall along the Florida panhandle as well as the first major hurricane (Category 3+) to directly impact Georgia since the 1890s. In southwest Georgia, wind gusts as high as 115 mph were recorded in Donalsonville. Within the NWS Atlanta/Peachtree City county warning area, winds gusted over 70 mph in portions of central Georgia on the evening of October 10th, leading to widespread tree damage and power outages as well as severe crop damage, especially to cotton and pecan crops. Additionally, a few brief tornadoes in the outer bands of Michael caused sporadic damage in portions of the the area while heavy rainfall led to localized flooding. Michael quickly exited the state as a tropical storm on the morning of October 11th.
    For more information on the catastrophic damage experienced within the NWS Tallahassee area, click here.
    This infrared satellite image was taken as Hurricane Michael entered southwest Georgia as it maintained a Category 3 intensity on the evening of October 10, 2018. 
    (Click the map to enlarge it.)
     

    Damaging Winds:
    Within the portion of central Georgia in the NWS Atlanta/Peachtree City county warning area, sustained winds of 40-50 mph with gusts in the 60-75+ mph range downed countless trees and power lines. Numerous trees fell onto homes and businesses, causing additional damage. The peak wind gust officially recorded within the local warning area was in Arabi, GA where a 76 mph gust was recorded. Even stronger wind gusts well over hurricane force (74+ mph) were recorded in southwest Georgia in the NWS Tallahassee county warning area. Power outages lasted up to a week or even a bit longer for some areas. Below is a map displaying many of the strong wind gusts recorded across the state during Hurricane Michael. 
    Note: Wind gusts were likely stronger than displayed for a number of locations in central and south Georgia; however, recording instruments failed as electrical power and communications were lost.

    Heavy Rainfall:
    Rainfall totals reached in excess of 5" in some locations. Though the ground was relatively dry due to recent dry weather, these rainfall totals led to isolated instances of flooding, including a few roads that were washed out.

    Tornadoes:
    Three brief tornadoes touched down in the outer bands of Hurricane Michael on the evening of October 10th. See the specifics on these tornadoes below.
      1) Peach County Tornado: A brief EF-0 tornado snapped a few pine trees along Carver Drive, just south of Fort Valley State University.

The tornado first touched down along Avera Road southwest of Roberta, snapping a few small trees and branches near a residence just east of the Hammett Road intersection. The tornado continued west-northwest, crossing Pope Road and Carroll Road, snapping and uprooting trees with the high-end EF-0 range. The tornado continued to move west where it intensified to a high end EF-1 with estimated maximum winds of 110 mph along Flint River Estates Road. Numerous trees were snapped from 10 to 20 feet off the ground or uprooted, including many hardwood trees. Several homes along the road were damaged by falling trees. A detached workshop at one of the homes was completely destroyed. The survey revealed that the garage was open with the opening facing the direction of the maximum winds, which led to its complete failure. The tornado continued westward, snapping trees as it crossed State Route 128 where it damaged another residence with falling trees. The tornado continued west, crossing Hortman Road, where a few small trees and large branches were downed before lifting as it approached Walker Chapel Road.

    Numerous trees were snapped or uprooted along the tornado track. This outbuilding was destroyed by the tornado. 3) Fulton County (Atlanta) Tornado: A brief tropical-cyclone tornado touched down just a couple miles southwest of downtown Atlanta along Dill Avenue SW. Along this road, several large trees were snapped. This is where a Tornado Debris Signature (TDS) was initially observed and where a peak wind of 75-80 mph was estimated. The tornado quickly crossed Highway 29 (Lee Street SW), downing several more trees along Avon Avenue SW between Princess Avenue SW and Wyland Drive SW. No further notable damage was seen downstream from this point.

    Design Update - 11/27/21

    By NorthGeorgiaWX,


    Media Room
    As you can see, this has been a slow project, but we're finally getting somewhere. I have more plans and now have a speaker list and screen size.
    This is going to be a 7.2.4 home theater system, and that's really about all you can fit into the room. Again, my primary focus is on music and sound quality so the video part takes a second seat. 🙂 But with a 9 foot wide screen and the correct projector, that's not going to be too bad either. 
    Here's the room. To get your bearings, the top of the image is the outside wall and those red diagonal lines are the windows. The right side of the image is the front of the room and the bottom of the room is open to a hallway. You can start to see some of the challenges with sound management since the room has glass on one side and open on the opposite side. Those speakers you see out in the middle of the room will be in the ceiling and the speakers at the top and bottom (either side of the sitting area) are the left and right surrounds. On the back wall are two rear channel speakers and a subwoofer (actually a dual cone subwoofer, more on the speakers below). 
     

     
     
    Here's a side view (left) looking toward the windows. They will have a motorized blackout shade that we can control remotely. There are actually 5 treys in the ceiling. There is one large one and four other ones inside. There will be LED lights that will make the treys look like they are floating below the ceiling. 
    The right image is the front of the room. It shows the three front channel speakers and the other dual cone subwoofer. Everything is hidden, you won't see any speakers or anything else. The projector screen is 9 feet across but the height will be determined on whether I go with 16:9 or 2.35 aspect ratio, and I still haven't decided on that, nor has the projector been picked out. If I go with 2.35 the shelf on top stays, if I go 16:9 it has to go. 
    The side view looking out the windows (the three windows have shades over them) is on the left, with the front of the room to the right. The right side image is looking at the front of the room.

     
    I finally have a speaker list! YEA!!!
    Front Channel - All three speakers for the front channel will be identical, and I'll be using the Wisdom Audio Sage Cinema Line 2 speakers. The center speaker will be behind the screen while the other two to the sides. I will need a total of 6 channels of amplification to power these speakers as each speaker needs two dedicated channels.
    SAGE CINEMA LINE 2 - Wisdom Audio
    WWW.WISDOMAUDIO.COM Targeting high-performance media rooms and private cinemas, The Sage Cinema Series models are dedicated to hidden installations behind projection screens and fabric walls. The Line 2 features the award-winning Sage 24” Planar Magnetic Drivers, and six long linear excursion, high-output woofers. The Line 2 delivers a new level in...

     
     
    Surrounds and ceiling speakers - There are two side surrounds, two rear surrounds, and four ceiling speakers, and they will all be the Wisdom Audio Sage Cinema Point 2 V2 speakers. I like the idea of keeping the same speakers for all the surrounds and ceiling. I will need 8 channels of amplification to power these.

Perfectly suited for home theater and media rooms, C20i produces the highest level of sonic refinement and performance available from an in-wall speaker. The Sage C20i includes a large planar magnetic driver – and...
     
     
    Subwoofers - There will be two subwoofers in the room, one in the front and one in the rear. Each cabinet contains two 15" cones and a 4000 watt amp, so a total of 8000 watts of bass power. We will be crossing over to the subs at 80 hz. 
    SubMersive F2+ & F2-Slave Subwoofer – Seaton Sound, Inc
    SEATONSOUND.NET  
    Ours will be hidden so we'll just get the plain black version. They do make prettier versions though. 🙂 They also make other models of subwoofers.

     
    Main Processor - Of course the main processor was decided right up front, and that is the Trinnov Altitude 16. Hands down the best processor in the world. Plus I am thrilled to have the best calibrator in the world coming to calibrate the room. His name is Adam Pelz and he's the expert when it comes to managing the Trinnov Processor, and he's worked extensively with Wisdom Audio Speakers. To give you an idea of his demand, he's in Bahrain right now doing a calibration. 🙂

    WWW.TRINNOV.COM The Altitude16 builds on the success of the Altitude32 and Trinnov's exclusive platform with 20-channel immersive sound decoding and best-in-class Room Correcti

     
    Amplifiers - It will come down to one (or both) amp series in their line. I will need 11 channels of ~500 watts each, so 5,500 watts of power. That doesn't include the subwoofers. 

    AT54X Series - Amplifier Technologies Inc.
    ATI-AMP.COM These amps come with 1 to 4 channels of amplification, each channel making 500 watts of power. This was going to be the amp I was going to use and may still be. I would need three of these.

    But... these are an option I am seriously considering. 
    Signature Series 6000 - Amplifier Technologies Inc.
    ATI-AMP.COM
    These come with 1 to 7 channels of amplification. It makes slightly less power (450 watts) into 4 ohms (which is the impedance of all the speakers) than the other amp, but these are sonically better amps. I could get away with two of the 7 channel amps. I need to talk to Adam and Shawn to see if this power output would work ok with the main speakers, and make sure I can achieve the required sound levels.


     
    Time to start ordering equipment!

     
    Projector
    Last but not least, we've settled on the JVC DLA-NZ9 projector. Since we have a bright room, I needed a projector that could give decent light without always closing the blackout shades, and this new JVC projector fits the bill.

    November 4, 1927 
    A great Vermont flood occurred. Tropical rains deluged the Green Mountain area of Vermont causing the worst flood in the history of the state. Torrential rains, up to 15 inches in the higher elevations, sent streams on a rampage devastating the Winooski Valley. Flooding claimed 200 lives and caused 40 million dollars damage. The town of Vernon reported 84 deaths. Flooding left up to eight to ten feet of water in downtown Montpelier VT. (2nd-4th) (David Ludlum) (The Weather Channel) 

    November 4, 1985 
    A super wet Gulf storm dumped upwards of fifteen inches of rain in the mountains of Virginia and West Virginia causing devastating damage and claiming forty lives. (Sandra and TI Richard Sanders - 1987) 

    November 4, 1987 
    Thirty-two cities in the eastern and south central U.S. reported record high temperatures for the date. Highs of 74 degrees at Portland ME and 86 degrees at Fort Smith AR equaled November records. It was the fourth day of record warmth for Beckley WV, Memphis TN and Paducah KY. A cold front ushered much colder air into the north central U.S. Gale force winds lashed all five Great Lakes. (The National Weather Summary) 

    November 4, 1988 
    Thunderstorms developing ahead of a fast moving cold front produced severe weather over the Tennessee Valley and the Central Gulf Coast States during the afternoon and evening hours, and into the next morning. Thunderstorms spawned nineteen tornadoes, including eleven in Mississippi. The last of the nineteen tornadoes killed a woman in her mobile home in Lee FL. A tornado in Culbert AL injured sixteen people, and caused two million dollars damage. Thunderstorms also produced baseball size hail in Alabama. Unseasonably hot air prevailed south of the cold front. McAllen TX was the hot spot in the nation with a high of 102 degrees. (The National Weather Summary) (Storm Data) 

    November 4, 1989 
    Snow and high winds plagued parts of Colorado and Wyoming. Winds gusted to 71 mph near Wheatland WY, and reached 80 mph west of Fort Collins CO. Up to five inches of snow blanketed Yellowstone Park WY closing many roads. Snow also blanketed northern Minnesota, with seven inches reported at Baudette. (The National Weather Summary) (Storm Data) 

    November 4, 1991
    Winter-like temperatures produced considerable crop damage over Sumter County. Overnight lows dropped into the mid to upper 20's the mornings of November 4th, 5th and 6th with daytime highs in the 50's. Damages to crops, including cucumbers, green beans, peanuts and squash were estimated at $1 million. (NWS Atlanta)

    Most people that aren't car people have no clue about this car. When you first tell people you own a Cadillac most minds conjure up grandpa's finned Cadillac with a 20 foot hood, but this ain't grandpa's Cadillac anymore. In today's world, Cadillac's are known for innovative performance on par with the best the rest of the world can offer, and this car is no exception. 
    With the introduction of the V Series models, Cadillac stepped up to the world of serious high performance cars. The initial design criteria for the 2012 ATS debut was based on the BMW E46 3 Series. 

    But Cadillac needed to bump up the performance even more, and that's how the V Series got started. The V Series is Cadillac's version of Chevrolet Corvettes. 
     
    This car is a 2017 coupe with 11, 700 miles and these were the production numbers. As you can see, there aren't a lot of these around, especially the coupes.

So I took all the options on the car and plugged it in and came up with this. And no, thankfully the original owner took the depreciation hit because this is not close to what I paid (the car was listed at $44K with 11, 700 miles).  Goes to show you why you don't want to buy a new car. 😉 












     
    In the next post I'll talk about my planned modifications. 🙂 Of course, what red blooded car guy wouldn't make changes??? 🙂 And I think the changes are going to be awesome. Oh... she has a name now.

    The main focus on this article is not to make a winter forecast, but  to explore what effects El Nino's and teleconnections have on winter weather across the southeast. One of the main sources of data in this report comes from a weather friend of mine that I call "Brother Larry". Larry would prefer to remain anonymous, so from here on out you'll hear me refer to Larry as "Brother Larry". 🙂  Larry has a wealth of information about the weather history in Georgia, and I'll be using a lot of his findings to help give you an idea how this winter may turn out, based on the environment created by the El Nino, as well as several other factors. Again, this data is based on analog years, or those years that most closely identify with the current patterns, so keep that in mind. Analog's are not perfect, but they do give us a very good idea about how things have happened in the past and how they may happen again in the future. 
    Again, almost all of the text below (other than a few of my own edits and additions) is from Larry, and he gets all the credit for the research and stats.
                          This data was compiled by taking a list of 26 “cold” US winters (Dec/Jan/Feb) since 1894 -1895 (i.e., the coldest 23%) for the eastern third of the US. This requires solid, widespread, below normal anomalies, and requires the southeast to be pretty chilly itself. The two maps to the right were created with data from the list of years below, but that dataset only goes back to 1948, so the maps I'm displaying are not 100% complete with the years in the list. Here's the list of those winters, and you can see the years I used on the maps themselves. 
    Also, Larry's 26 coldest winters study was done the better part of 10 years back, since then, it is possible that some of 09, 10, 13, 14, etc. could be added, although he is not reassessing those now.   2002 - 2003 1995 - 1996 1993 - 1994 1981 - 1982 1980 - 1981 1978 - 1979 1977 - 1978 1976 - 1977 1969 - 1970 1968 - 1969 1967 - 1968 1963 - 1964 1962 - 1963 1960 - 1961 1947 - 1948 1939 - 1940 1935 - 1936 1917 - 1918 1911 - 1912 1909 - 1910 1904 - 1905 1903 - 1904 1901 - 1902 1900 - 1901 1898 - 1899 1894 - 1895 Temperature Anomalies Precipitation     Nino Base State
    ENSO Regions ONI Chart from Golden Gate Weather Services - Forecast So now that we have our list of base years, let's look at the base Nino state for those winters. Before we can do that, we need to take a look at the various Nino/Nina classifications. Graphs and Charts

    The Oceanic Niño Index (ONI) has become the standard that NOAA uses for identifying El Niño (warm) and La Niña (cool) events in the tropical Pacific.  The ONI is defined as the running 3-month mean SST anomaly for the Niño 3.4 region (i.e., 50N-50S, 120W-170W).  Events are defined as 5 consecutive overlapping 3-month periods at or above the +0.5 anomaly for warm (El Niño) events and at or below the -0.5 anomaly for cold (La Niña) events.  The threshold is further broken down into:  Weak (with a 0.5 to 0.9 SST anomaly) Moderate (1.0 to 1.4) Strong (1.5 to 1.9) Very Strong (≥ 2.0)  For the purpose of this blog post, for an event to be categorized as weak, moderate, strong or very strong, it must have equaled or exceeded the threshold for at least 3 consecutive overlapping 3-month periods. Here's an analysis of the 26 cold winters by ENSO state:  Strong Nino: 0 of 26 (0%) Moderate Nino: 1 of 26 (4%) Weak Nino: 9 of 26 (35%) Neutral positive: 4 of 26 (15%) Neutral negative: 5 of 26 (19%) Weak Nina: 6 of 26 (23%) Moderate Nina: 1 of 26 (4%) Strong Nina: 0 of 26 (0%) Dec-Feb temperature anomalies during weak Nino's Notice that out of all the cold years, the majority of them occurred during weak Nino's (35%). Also notice that out of all of those cold winters, none of them occurred with a strong Nino or a strong Nina. 

    The map on the left depicts the temperature anomalies that occurred during a Weak Nino. Due to the data only going back to 1948, all of the years are not depicted, but this will give you a good idea. 

    As you can see, a weak Nino is what we'd like to see come Dec-Feb. If the current one stays too strong, it could severely limit our cold this winter based on past analogs. keep in mind, Larry's study is based on temperatures, not precipitation.       Nino and the Pacific Decadal Oscillation (PDO)
    +PDO or Warm State -PDO or Cold State   PDO Index (http://www.daculaweather.com/4_pdo_index.php)
    While it's easy to look at one specific weather pattern, there are many factors that determine how a winter will turn out, with the ENSO state being just one of those. But there are other teleconnections and long term patterns that also have an effect on our winter weather, and they all work in tandem with each other.  Graphs and Charts

    Now we are going to turn our attention to the PDO state or Pacific Decadal Oscillation. First, the definition from the National Center for Environmental Information:

    "The Pacific Decadal Oscillation (PDO) is often described as a long-lived El Niño-like pattern of Pacific climate variability (Zhang et al. 1997). As seen with the better-known El Niño/Southern Oscillation (ENSO), extremes in the PDO pattern are marked by widespread variations in the Pacific Basin and the North American climate. In parallel with the ENSO phenomenon, the extreme phases of the PDO have been classified as being either warm or cool, as defined by ocean temperature anomalies in the northeast and tropical Pacific Ocean. When SSTs are anomalously cool in the interior North Pacific and warm along the Pacific Coast, and when sea level pressures are below average over the North Pacific, the PDO has a positive value. When the climate anomaly patterns are reversed, with warm SST anomalies in the interior and cool SST anomalies along the North American coast, or above average sea level pressures over the North Pacific, the PDO has a negative value (Courtesy of Mantua, 1999). " 

    Here's an analysis of the cold 26 winters by DJF averaged PDO status: + PDO: 18 of 58 (31%) - PDO: 8 of 57 (14%) Again, much as it was with weak Nino's, many of our coldest winters occurred during a + PDO state, while only 8 out of 57 occurred during a negative PDO state.      Nino and the North Atlantic Oscillation (NAO)
    In order for us to get long lasting cold air that stays locked in, we need some blocking. There are several teleconnection patterns that aid in developing this blocking, one of which is the North Atlantic Oscillation or NAO. Graphs and Charts Negative NAO (-NAO) Positive NAO (+NAO) Here's the definition of the NAO:
    "The North Atlantic Oscillation (NAO) is a climatic phenomenon in the North Atlantic Ocean of fluctuations in the difference of atmospheric pressure at sea level between the Icelandic low and the Azores high. Through fluctuations in the strength of the Icelandic low and the Azores high, it controls the strength and direction of westerly winds and storm tracks across the North Atlantic. It is part of the Arctic Oscillation, and varies over time with no particular periodicity."
    Strong positive phases of the NAO tend to be associated with above-average temperatures in the eastern United States and across northern Europe and below-average temperatures in Greenland and oftentimes across southern Europe and the Middle East. They are also associated with above-average precipitation over northern Europe and Scandinavia in winter, and below-average precipitation over southern and central Europe. Opposite patterns of temperature and precipitation anomalies are typically observed during strong negative phases of the NAO. For us, negative is what we're looking for in the winter. 

    Let's take a look at the analysis of the cold 26 Dec-Feb winters by averaged NAO status:
      – NAO: 19 of 48 (40%) + NAO: 7 of 67 (10%) Again, a large number of the cold winters had a negative NAO.      Piecing It All Together...

    Now let's take the combination of the ENSO state (in our case, Nino), and factor in the PDO and NAO and let's see what we get. Here's the analysis of the 26 cold winters by a combination of Dec-Feb averaged PDO and NAO status: + PDO/-NAO: 12 of 25 (46%) - PDO/-NAO: 7 of 23 (30%) (all 7 had (PDO – NAO) > 0) + PDO/+NAO: 6 of 33 (18%) - PDO/+NAO: 1 of 34 (3%) Things start to change a little. Obviously, the combination of +PDO and -NAO are the best combination, and that makes perfect sense. During the positive phase of the PDO, the wintertime Aleutian low is deepened and shifted southward, warm/humid air is advected along the North American west coast and temperatures are higher than usual from the Pacific Northwest to Alaska but below normal in Mexico and the southeastern United States. Add the effects of the blocking provided by the NAO and you lock in the cold air instead of having it rush out to sea.  Now, let's really lay it out.
    Here's "Brother Larry's" analysis of the 26 cold winters by a combination of ENSO state and Dec-Feb averaged PDO and NAO status:

    Strong Nino: +PDO/-NAO: 0 of 6 (0%) -PDO/-NAO: 0 of 1 (0%) +PDO/+NAO: 0 of 7 (0%) -PDO/+NAO: 0 of 1 (0%)
    Moderate Nino: +PDO/-NAO: 1 of 2 (50%) -PDO/-NAO: 0 of 0 (N/A) +PDO/+NAO: 0 of 0 (N/A) -PDO/+NAO: 0 of 2 (0%)
    Weak Nino: +PDO/-NAO: 6 of 7 (86%) -PDO/-NAO: 2 of 2 (100%) +PDO/+NAO: 1 of 2 (50%) -PDO/+NAO: 0 of 4 (0%)
    Neutral Positive: +PDO/-NAO: 2 of 4 (50%) -PDO/-NAO: 0 of 3 (0%) +PDO/+NAO: 2 of 10 (20%) -PDO/+NAO: 0 of 5 (0%)
    Neutral Negative: +PDO/-NAO: 1 of 3 (33%) -PDO/-NAO: 2 of 7 (29%) +PDO/+NAO: 2 of 10 (20%) -PDO/+NAO: 0 of 5 (0%)
    Weak Nina: +PDO/-NAO: 2 of 2 (100%) -PDO/-NAO: 3 of 5 (60%) +PDO/+NAO: 1 of 4 (25%) -PDO/+NAO: 0 of 7 (0%)
    Moderate Nina: +PDO/-NAO: 0 of 1 (0%) -PDO/-NAO: 0 of 3 (0%) +PDO/+NAO: 0 of 0 (N/A) -PDO/+NAO: 1 of 4 (25%)
    Strong Nina: +PDO/-NAO: 0 of 0 (N/A) -PDO/-NAO: 0 of 2 (0%) +PDO/+NAO: 0 of 0 (N/A) -PDO/+NAO: 0 of 6 (0%)     Conclusions...
    Weak Nino’s give the highest percentage chance for cold of any of the ENSO states by far (with weak Nina’s second); however, a combo of -PDO/+NAO seems to make it difficult even for weak Nino’s. A very impressive 13 of 16 (81%) of the aggregate of weak Nino's and weak Nina's with -NAO were cold. Don't ever bet on cold with either a strong Nino or a strong Nina since none of the 23 were cold. +PDO about doubles the percent chance for cold versus a -PDO. A -NAO more than doubles the percentage chance for cold versus a +NAO and a somewhat higher chance than a +PDO gives. So, I give small edge to –NAO over a +PDO regarding cold prospects. Regardless, both are very important. A +PDO/-NAO combo gives close to twice the percentage chance for cold versus the percentage chance for all PDO/NAO combos in the aggregate. A -PDO/-NAO is the next best combo for cold prospects, but mainly if NAO is more negative than PDO. Don't ever bet on cold with a combination of -PDO/+NAO, since only 1 out of 34 were cold. If there is a +PDO, the chances for a –NAO appear to be high for only weak to moderate Nino’s. The chances appear to only be about 50-50 for strong Nino’s. For neutral ENSO, the chances seem to be surprisingly low (partial negative correlation suggested). The best shot at a +PDO/-NAO combo appears to be with a weak to moderate Nino's. On the other hand, only 3 of 34 (9%) Nina’s had a +PDO/-NAO. A pretty high 17 of 34 (50%) Nina’s had a –PDO/+NAO. A +PDO is difficult with a moderate to strong Nina. Only one out of 16 (6%) had one. A –PDO seems rather difficult with a strong Nino, only 2 out of 15 (13%) had one. +PDO and –PDO winters are about evenly split. But +NAO winters have been a bit more common than -NAO in long term: 58% vs. 42%.     Winter Precipitation
    Regarding wintry precipitation for Atlanta, when looking at the three standalone super Nino's (1972-1973, 1982 -1983, 1997-1998) as well as the six strong to super strong 2nd year Nino's (1877-1888, 1888-1889, 1896-1887, 1905-1906, 1940-1941, 1987-1988), Atlanta more often than not, had one major winter storm, but not always: 1877-1888: 2.5" 1/3/1878 & a non-major freezing rain followed on 1/9/1878 1888-1889: 6" 2/21/1889 1896-1967: 6.2" 12/2/1896 1905-1906: 6.2" for the season including 3.5"+ major 1/26/1906, measurable snow D, J, and F 1940 -1941: only T of snow 1972 -1973: historic ZR 1/7-8/1973, which included 1" mainly ice pellets; (also, historic snow hit central GA in Feb though Atlanta missed that one) 1982 -1983: 10.3" S/IP for season including 7.9" 3/24/1983 (heaviest since 1940) and measurable snow J, F, and M 1987- 1988: 4.2" of mainly IP 1/7/1988 (would have been ~8" if all snow) 1997- 1998: only 0.6" 12/29/1997

    Good morning!
    I guess you heard the rain moving through during the overnight hours, it is now pushed southeast of Lincoln and today to should a relatively dry day to kick off the ProSolo!
    This is a combined radar/water vapor loop, and the numbers are dewpoints. Much drier air is moving into southeast Nebraska and today should feel great. About 15 seconds into the loop I switch from dewpoint to temperatures.

    Lincoln Friday AM.mp4  
    The NWS hour by hour forecast looks great for today, but tomorrow may be damp at times. 
     

     
    As far as next week goes, no major rainfall in the forecast for now. You guys may luck out...
     
    So nothing today that should interfere with the competition. Go fast, have fun!

    Update - 07/16/21

    By NorthGeorgiaWX,


    Car
    Got my car back from Balanced Performance Motors today after having a few changes made to it this week. 
    I had to replace the low pressure fuel pump (LPFP) that I had purchased from Tapout Tuning since it couldn't hold enough pressure on E85. It was supposed to be a "Stage 2" pump, meaning it wouldn't have any issues running straight E85, but testing during the tuning process showed that the pressure was dropping to 45 lbs or so which is not anywhere close to what it needs to be. It will be sent back for a refund. This is a picture of the pump/housing that came out. It is a DW400 pump but apparently the venturi in the housing is the restriction to the flow and the reason for the low pressure. 

     
    I installed an XDI Stage 1 LPFP and it is supposed to be sufficient to run E85 up to the limit of the stock turbos.
    Specs:
    OEM ATSV ACDELCO LPFP Spec’s:
    377 LPH without back pressure.
    215 LPH at 70 PSI
    XDI Stage 1 Spec's: 
    435 LPH at no back pressure
    265 LPH at 70 PSI
    23% Increase overall
    Maximum Pressure
    >80 psi at full flow (PLV opening pressure 85-90 psi, stock is 70-75 psi)
    See chart.
    Fuel Compatibility: all known fuels, all Ethanol blends
    Fitment:  100% OEM, no cutting, no crimping
    Tuning Support:  HPT, Trifecta

     
    While the car was there, I had them replace the plugs with NGK Ruthenium plugs since I knew it still had the stock plugs.
    The plugs were gapped at 0.026" which is what is recommended for these cars running the boost levels we are seeing. 

     
    I also installed a new Renick cold air intake (CAI), here's a picture of the installation. Click to enlarge. The new system consist of two equal length tubes each with its own filter.  "Equal length ensure that the compressor wheel on each side of the LF4 has identical RPM response as they spool up and spool down. The LF4 has matched mirror turbos for efficiency why not have a flow matched intake as well? This helps make the engine respond identical on both banks with maximum efficiency. "
    The CAI kit also came with an oil catch tank to prevent any oil from reaching the turbos.

     
    So... I need to take the car out and get a pull or two and send it off to Justin to refine the tune a little. The plan now is to get the car on the dyno the last week in July to see what it's making, but it should be somewhere between 620-640 whp. Can't wait. Assuming nothing breaks, I'm done with changes for this car for a while.  Famous last words... 🙂

    Garage Update - 12/20/21

    By NorthGeorgiaWX,


    Car
    More progress made today and they may be finished painting tomorrow 🤞
    The ceiling is done. They need to go back and recut the red in a few places, and there are a few spots of ceiling paint on the wall that they will touch up. The louvered door that covers the refrigerator went back on this morning. 
    The garage door side is the focus now and they made good progress on that today. The paint wasn't dry when I snapped this picture, but you can see some drier areas on the left door. All of the trim around the doors will be painted that same color. You can click to enlarge any image.

     
    Here's the opposite wall. The trim and ceiling are darker than they look in the picture. 

     
    This wall is pretty much done except for a few minor touch ups.

     
    This picture is not in focus. The camera was having a hard time focusing on the red wall and I should have fixed that, but hey... it is what it is. They still have some trim paint to do on this wall, the door needs to be painted, and some cut in work on the red, but almost done. You can also see where the vanity and sink will go back in. I need to call them to see when it might ship. I ordered that in October and I think it was a 12-14 week lead time... it should be about done. 

     
    You can see the blue in the ceiling color even though the camera doesn't show it exactly like your eyes see it. 

     
    The garage door wall should look great once the doors and trim are finished.

    Suspension

    By NorthGeorgiaWX,


    Car
    I'm a handling guy, always have been. I love the curvy roads and will go out of my way to take those every chance I get. I started autocrossing cars back in 1973 and have continued off and on for all these years, and the love of driving has only increased as I've gotten older. And it's not just turns, I also want a car that can stop much faster than it can accelerate. This one does it all.
    In the stock form, this car will pull a steady 1.03 g's on a skidpad, and many people have never even been in a car pulling 1 g much less anything more. But... if it can pull that much stock, it can pull more modified. 🙂 Therefore, since I cannot leave well enough alone, I must do something about this. 😜
    So, I'm keeping it relatively simple. I'm not trying to go crazy with anything I'm doing, since the car already does everything so well, it's all about enhancing. So two suspension changes and new wheels and tires, that's it. Since the car already has shocks better than anything I could buy elsewhere, those are left untouched. That leaves the springs and sway bars. I've looked at multiple spring sources and have narrowed it down to three companies, Renick Performance, Eibach, and Weaponsxmotorsports. I was speaking with a fellow ATS-V owner today (thanks Michael!) and his car uses Eibach springs and exactly the same wheel/tire sizes (his are Forgeline F14's) that I will be using. Take a look at how the spring/wheel/tire combo looks. I'd say perfect, but that's just me.  🙂 


     
    Here's how the stock wheel and tire sizes match up to the new ones that I will be running. I don't have the weight of the new wheels but I believe the front is around 21 lbs. 

     
    Once I decide on the springs I'm going with I'll be good to go. I'm also checking on sway bar sizes. The factory list different bars so it's difficult to judge what I need to get. It appears the front bar is  a hollow 29 mm OD and 4.6 mm wall thickness. The rear is 25.4 mm with a 3.81 mm wall, and both are made from SAE 1020 equivalent material and the bars are heat treated and shot peened. It is hard to get this kind of information about the aftermarket bars, but unless I do, I'm not spending the money to get any. 
    The tires will be Michelin Pilot Sport 4S tires and these are warm weather only tires. Tires make a tremendous difference in handling and the performance varies widely between the various brands. The Michelin's are considered to the among the best if not the best high performance street tire.

     
    As soon as I can get a little more information, I'll update this. The springs are out of stock no matter who you go with... they must all be made in China. 😉

    An unusually late season tornado struck the central Kansas town of Great Bend killing eleven persons along its 35 mile track. The tornado destroyed 160 homes in Great Bend killing 11 persons and causing a million dollars damage. Hundreds of dead ducks dropped from the sky northeast of the track's end. (The Weather Channel) 

    November 10, 1975 
    Another freshwater fury hit the Great Lakes. A large ore carrier on Lake Superior, the Edmund Fitzgerald, sank near Crisp Point with the loss of its crew of 29 men. Eastern Upper Michigan and coastal Lower Michigan were hardest hit by the storm, which produced wind gusts to 71 at Sault Ste Marie MI, and gusts to 78 mph at Grand Rapids MI. Severe land and road erosion occurred along the Lake Michigan shoreline. A popular hit song by Gordon Lightfoot was inspired by the storm. (David Ludlum) (Link)

    November 10, 1984
    Severe weather swept across north Georgia causing widespread damage. An F-2 tornado touched down near Duluth in Gwinnett County at the Chattahoochee Mobile Home Park where 10 mobile homes were destroyed and 8 people were injured. The tornado lifted at the Hilltop Manor Subdivision where it damaged many homes.
