SHORT TERM. (Issued 200 PM CST Tue Mar 2 2021)

Tonight through Wednesday night:

Gusty southwest winds will gradually ease with a slackening pressure gradient and some decoupling. A cold front will work through the state. This will result in a low level thermal trough across the cwa for Wednesday. So we may see a bit more in the way of cloud cover. The Bufkit sounding from the NAM appears to have too great of depth of moisture while the GFS may be a bit scant. For now will trend toward a cloud/sun mix. Winds will be northwest at the outset but will then bend northeast off the lake for the afternoon. A ridge of high pressure will then settle across the area for Wednesday night.

Collar

LONG TERM. (Issued 200 PM CST Tue Mar 2 2021)

Thursday through Saturday:

The high will dominate this period with quiet weather. Looks like a light wind regime so we will likely see some form of an onshore flow. Expect a good deal of sunshine.

Sunday through Tuesday:

A mild return flow sets up around the departed high and an approaching low pressure system. Some of the guidance looks too cool. Once the influence of the lake wanes with a stronger southwest wind taking shape, the better warming should make it all the way to the lake. May need to eventually add some pops for early in the week with a lead shortwave interacting with the miler and increasingly moist flow. Main wave looks to eject towards the middle of next week with enhanced warming and increasing rain chances.

Collar

AVIATION. (Issued 200 PM CST Tue Mar 2 2021)

VFR for much of the period with gusty southwest winds into early this evening. As some decoupling occurs there will be some concern for wind shear as southwest to west 925 jet max swings through. A cold front will slide through the state overnight shifting the winds to a more northerly direction. Will have to keep an eye out for possible post frontal MVFR cigs within the low level thermal trough regime that sets up into Wednesday. Some mixed signals from the models on degree of moisture.

Collar

MARINE. (Issued 200 PM CST Tue Mar 2 2021)

Will let marine headlines stand. Tight pressure gradient resulting in strong southwest winds is proggd to gradually relax this evening with winds slowly bending to the west.
