KEY MESSAGES

- A Winter Weather Advisory remains in effect early this morning for a light wintry mix, including minor snowfall accumulations that may induce hazardous travel conditions as temperatures remain at or below the freezing mark.

- Cold, winter-like temperatures hold thru the entire week with lows each night falling into the teens and 20s. Single digit wind chills are forecast late Wednesday night into early Thursday morning for northern portions of southeast Missouri and southern Illinois.

- It's mostly dry after this system departs, despite small precipitation chances this weekend and again early next week.

DISCUSSION

Issued at 100 AM CST Tue Dec 2 2025

Our system will effectively complete its sweep early this morning as the surface reflected low shoots east and the deformation zone phased with the broader warm sector overrunning pcpn soon follows its departure. So far, it looks like a good swath of 1-2" occurred/is occurring within the more heavily banded pcpn, with lesser amounts outside of that...esp north and west. Surface temps are all now at freezing or below, so even as snow melt has occurred, still slushy roads may also have some icy slick patches develop at times as well...especially bridges/overpasses and the like. And even with some afternoon sunshine, temps will struggle to get much above freezing today, with highs only in the 30s everywhere. It will essentially be a 'how to deal with what's fallen' start to the day as the precipitating aspect of the event, for all practical purposes, looks like it will be done by 10-11z, perhaps earlier with current trending.

After a 1021 mb surface high ridges across the FA and TN Valley later today and tonight, another high about 10 mb stronger comes in and helps blast a reinforcing surge of arctic cold air across the FA Wednesday night-Thursday. So after a cool night tonight with around 20 degree lows, we recover into the 40s Wednesday as the first high shifts east, before plunging again into the 20s Wednesday night, with some upper teens in our northern reaches; north winds hold close to 10 mph, dropping wind chills into the single digits in our northwest counties on our CWA borders for parts of SEMO/SWIL. The cold sticks around thru the day Thursday with highs in the 20s north, and struggling to top the freezing mark south. And even with some air mass modification with time, below normal temps more winter-like with 30s/40s for highs and teens/20s for lows holds right on thru the weekend. There are some glancing blows for pops in the slight chance range but it's generally a dry period save for these spotty chances early weekend, late weekend, and early next week.

AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/

Issued at 100 AM CST Tue Dec 2 2025

After light snow winds down, MVFR to possibly at times IFR CIGS should linger into and perhaps through much of the day, particularly further east. Time/height cross sections reveal a lingering ribbon of low layer RH that expires around 00Z so presumably we should see terminals scatter their bases by then, perhaps earlier in the west.
