SHORT TERM. (This evening through Wednesday) Issued at 230 PM CST Tue Mar 2 2021
Another sunny and quiet, but windy day across the area, with a tight pressure gradient between high pressure over the Ohio River Valley and low pressure just north of the MN/Canada border. Southwesterly gusts from 25 to right around 40 mph had been observed through early afternoon. That strong southwesterly flow was ushering in much warmer air compared to yesterday, as early afternoon temperatures were well into the 30s, with a few readings in the lower 40s. A weak cold front associated with the low will sag southward into the area tonight followed by some shortwave energy currently along the MT/Canada border. The main question will be what results as said energy moves through early Wednesday morning. Overall consensus would suggest some clouds or fog at most with model soundings suggesting a struggle to saturate in the lower levels. On the other hand, the NAM does produce some light QPF near and east of the Mississippi River. That said, NAM soundings still show low level saturation being no deeper than 0.75 km and with omega through that layer being weakly negative or even positive, have a hard time seeing any precip. If it does get going though, could see some light freezing drizzle, but again this looks quite unlikely at this point. The rest of Wednesday looks quiet as surface high pressure builds back in and temperatures generally top out in the 40s.
LONG TERM. (Wednesday night through Tuesday) Issued at 230 PM CST Tue Mar 2 2021
Overall a quiet, warming long term period as we'll remain under northwesterly flow aloft being on the eastern periphery of upper level ridging over the central CONUS. 850 mb temperatures through Friday will generally be on either side of 0 C through Saturday before increasing into the 3 to 6 C for Sunday through Tuesday as the upper level ridge axis passes through. In turn, a vast majority of EPS members show widespread high temperatures in the 50s for that Sunday through Tuesday time frame. This should lead to plenty of melting of snow and river ice and some river rises, though melting will be a bit more gradual to start, as temperatures will likely be dropping below freezing through at least Friday night. After that, things will speed up, but with a good portion of what's left likely having melted by then, not anticipating any flooding issues in the near future, barring an ice jam.
Otherwise, precipitation chances look pretty low through through much of the period, though not 100% confident we'll stay dry through the weekend. Guidance continues to show various weak bits of shortwave energy sliding through or near the forecast area, with a few ensemble members still suggesting some light QPF at some point this weekend. However, a vast majority of guidance keeps the area dry, so not including any precip chances through Sunday. Slightly better agreement of a wave sliding through or just to the north sometime Monday with a surface boundary perhaps leading to some light precip, though confidence in strength of forcing and moisture availability remains low. A much stronger wave looks to take aim on the area for the very end of the period, but still some differences on timing. In short, precipitation chances are confined to Tuesday for now.
AVIATION. (For the 00Z TAFS through 00Z Wednesday evening) Issued at 519 PM CST Tue Mar 2 2021
VFR conditions are expected through Wednesday. The winds will diminish very early this evening as the low level inversion sets back up and cuts off the mixing. This will allow for a short period of low level wind shear at KLSE early this evening until the stronger winds aloft move off to the southeast. A weak cold front will pass through the area Wednesday morning. This will swing the winds around to the northwest but speeds will be pretty light. There could also be some scattered cumulus during the day behind the cold front.
