Good Saturday morning to everyone! Decided to use the new blog site instead of the old one, so it may look a little different here today!

But first, a reminder that I have a page that is devoted to the weather at Lincoln, so anytime you like to see what's going on there, use this link to check it out.

The bullseye for the severe weather keeps shifting around and luckily, Lincoln isn't in the worst of it. But even if it's not the worst, it's still the plains, and any big storm there can create significant issues. For the latest thoughts from the Omaha NWS office, here's a portion of their AFD, the highlights are mine.

Continued southwesterly flow aloft will keep us in a fairly active
pattern over the next several days.
 The primary concern at the
moment is the potential for severe weather across southeast Nebraska
and southwest Iowa Saturday afternoon and evening, as well as the
potential for additional heavy rainfall across already saturated
ground
. An upper low will continue to lift northeast through
southeastern Canada, as its associated surface low is pulled from
northern Minnesota to just northeast of the Great Lakes. High
pressure will fill in across the Dakotas and into northern
Nebraska and Iowa behind the departing surface low, keeping much
of the forecast area dry today. A cold front associated with the
Canadian low will become draped over far southeast Nebraska and
southwest Iowa as it links with a developing low over the CO/NM
border region. CAMS are in fairly good agreement in developing
showery precipitation along and south of the boundary late this
morning and into the early afternoon. A better chance for stronger
storms will occur across far southeast Nebraska and far southern
Iowa through the afternoon and evening hours.
Dewpoints will climb
into the upper 60's, possibly low 70's, with moderate instability
and up to 40-50 kts of 0-6 km bulk shear possible. While previous
convection will play a role in how far south the front sets up, if
stronger storms are able to sneak into southern portions of the
CWA, a few could be severe with the potential for large hail,
damaging winds and perhaps an isolated tornado. Heavy rain will
also be possible with any thunderstorms that do develop
. PWATs
will rise to 1.50-1.70, which is still near the climatological max
for May 25th. Any heavy rain that does occur would fall on
already saturated soils, leading to the potential for Flash
Flooding. Therefore, a Flash Flood Watch has been issued for this
afternoon through early Sunday morning.

Convection will likely continue through the overnight hours across
southeastern portions of the CWA before diminishing in coverage
Sunday morning. A shortwave will move into the region Sunday
afternoon, igniting convection across south central Nebraska and
western KS. This activity could eventually make its way northeast
into the forecast area during the evening and overnight hours,
bringing another chance for heavy rain, large hail and damaging
winds to the region.

Continued southwesterly flow will maintain an active pattern into
Monday with another Slight Risk for severe weather across the
northern 2/3 of the CWA.

 

Here's the latest Severe Weather Outlook from the Storm Prediction Center for today

There is a frontal boundary running across Lincoln right now, separating the cooler, drier air to the north (upper 40's to mid 50's) from the warm moist air to the south (mid 60's right now), but there could be some light showers moving through the flow. So of course, being Lincoln... you get a little of both. 🙂 

 

Temps and Dew Points - You can see that Lincoln is pretty much on the line, maybe a little on the warmer side right now.

Radar view from the Omaha NWS office - The dark line that you see passing through Lincoln represents the pressure, and the line just south of Lincoln represents 0.8" precipitable water values. The NWS is expecting those to rise to 1.5"-1.7" later today, indicating that the stationary boundary will shift northward.

Again, it will probably be a good idea to try to keep everything secure up front, so in case bad weather rolls in you don't have to scramble to gather everything up. It will all depend on where that boundary shifts, further north the greater chance for rain, further south will mean cooler and drier.

I'll be watching it for you today, hope everyone goes fast with no cones! 🙂 And hey... at least it isn't 100 degrees!

    • 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?
