Saturday, October 20 - Weather Talk



A daily summary of social media discussions about the weather.

Global ensemble packages continue their extended-range support for the idea of a cold, stormy pattern across the east around the 10/25 - 10/30 window. When guidance hones in early and often, the chances of a significant event increases. pic.twitter.com/hIccj7GAPm

Concerning the threat for a stormy regime across the eastern US during the last week of October, we can see the energy fueling that potential threat coming into play across the Pacific NW next weekend before being ejected into the Plains and eastern US around 10/28 - 10/30. pic.twitter.com/6AiWh3JXL7

Early start to winter there...

Still watching this threat. Possible that one of the EPAC tropical systems remnants moves NE across Mexico into Gulf and this serves as part of the complex pattern by late October/early Nov, perhaps hybrid/subtropical storm? Plenty to watch in the coming days.

Many communities over the northern half of Alabama will drop into the 30s early tomorrow and Monday morning. Best chance of frost will come early Monday morning when the wind will be near calm. Average minimum temperature doesn’t drop below 40 in Birmingham until December. pic.twitter.com/K2vj83u0zP

We are off to a snowy start across northern WI. An inch or two is already on the ground! If traveling, be sure to take it SLOW in ICE and SNOW!

Very interesting story of an event from October 1844

It was Buffalo, NY (I was born there over 100 years after this event)... It was a CATASTROPHIC weather event... It changed the lives of many ... and it was NOT snow !!!!!! "Something Moore" https://t.co/AxB8W9ZFAZ pic.twitter.com/AmR3Ad0HvZ

'tis the season! :-) Some areas are going from fall to winter already!

Moderate to heavy snow showers across northern WI this morning (1-2" for most). If traveling, be sure to take it SLOW in ICE and SNOW! #wiwx pic.twitter.com/1ltLHQ7zKv

I haven't seen anyone else post a radar cross section of #Michael, so here ya go. This is roughly along a radial outward from KEVX. This is 1733Z,12:33 p.m. CDT. Note the stadium effect in the eye, though it's skewed because the plot is ~40 miles wide but only ~10 miles tall. pic.twitter.com/dQOi5LqUJG

It's about to get chilly! A cold front is pushing through Georgia today and will bring lows tonight from the lower 30s in the NE GA mountains where a Freeze Warning is in effect tonight, to the upper 40s further south. Highs tomorrow will be around 60 for the ATL metro. #gawx pic.twitter.com/YGRJTitKKQ

A “fallstreak hole” is a large elliptical gap that can appear in altocumulus or cirrocumulus clouds when the supercooled water droplets abruptly freeze. These ice crystals then fall and leave a hole behind. This one was captured during a spectacular sunset at Falcon Field! #gawx pic.twitter.com/dYHjbm1Vlx

    • Gfs is hinting at a tropical system out of the Caribbean.  Pretty nasty at that. It has kept introducing it off and on.  With the big cool down and the movements of overall circulation what are you thoughts here?
    • Good morning!       And speaking of the closed off bowling ball, here's what that 500 mb anomaly looks like. THIS is what we want to see this winter. Big closed upper air lows can make their own cold air in the winter by drawing down much colder air from the upper reaches of the atmosphere.    These are the corresponding surface temperature anomalies... we're going to be well below normal for the first week of October.    Do you remember what last October was like? We were broiling in the mid to upper 80's with extremely dry conditions.   Don't want to ever see that again, that totally ruined fall.  Take a look at the Euro's thoughts on low temps for next Sunday morning.   Here are two images, one from the GFS and one from the Euro, showing a cross section of the temperatures from the surface to about 200 mb which is getting close to 40,000 feet. You can see the dips in the temperatures next week. The temps are in Celsius so the zero degree line is 32 degrees.   While we expect some rain between now and next weekend, it won't be a a lot. There is a decent chance of rain in advance of the bowling ball but nothing significant at the moment. This is the expected rainfall through Thursday morning.   So we'll warm up a little before we cool down, so just a little patience! 🙂 Hope everyone has a great Saturday!
    • Good morning! Man... it just seems like this month is flying by to me. Here we are coming up on the middle of fall and the 2nd busiest month for hurricanes, so that means there ought to be lots of weather to talk about, but right now we're in a lull.  This mornings map (300 mb winds and isobars/dewpoints/water vapor/radar) shows a mostly zonal flow across the northern tier of the US. You can see the weak cold front trailing down though TN/AR/TX. You can also see how the southeast is still in the moisture while the northern and western parts of the US are dry.      Here's a look at the upcoming temperatures for selected areas around north Georgia. These are the official NWS forecast temps. Notice the end of the week.   The rain is about over but there could be a light shower/drizzle passing through, these are the rainfall expectations through 8 pm this evening.   So not much going on to get excited about. After having 5-7 storms in the Atlantic at once, we now have zero.    Yesterday's CoCoRaHS rainfall measurements look like this. I feel very alone up here.... 🙂   That's it! 🙂 I hop everyone has a great Friday!
    • Sorry, missed your question. I guess you've already gotten the answer. 🙂  
    • Any update on expected wind gusts or are we still just looking at breezy conditions if anything?
