KEY MESSAGES
- Powerful northwesterly winds continue through the morning before tapering through the remainder of Wednesday.
- Light, mixed-precipitation chances (20-30%) Wednesday night into Thursday, followed by a return of colder temperatures for the weekend.
- Another round of light snow is possible (20-40% chance) Friday night into Saturday.
FRIDAY AND THE WEEKEND
Behind the exiting system, cooler air builds in on Friday. Highs near freezing will fall shy of seasonal norms. Even colder temps are expected on Saturday and Sunday as an arctic airmass settles into the upper Mississippi River valley. AM Lows are forecast to slip into the single digits. Sunday morning wind chills may dip as cold as -20 to -10 for areas east of a line from Omaha to Norfolk.
Global deterministic models indicate weak ridging across the area early next week lending itself to moderating temperatures. C'mon global deterministic models!
AVIATION /06Z TAFS THROUGH 06Z THURSDAY/
Issued at 1105 PM CST Tue Dec 9 2025
VFR conditions are expected to prevail through the TAF period. There is a low (10-30% chance) MVFR ceilings reach OMA tonight. While most guidance keeps these ceilings east of the terminal, a brief reduction to ceilings may develop. The main aviation concern continues to be the very strong northwest winds. Any LLWS is expected to subside as the strongest winds overspread the region over the next several hours. Peak winds of 40 to 50 kts are expected through the night into the early morning. Winds will begin to weaken, but remain strong, later this morning into the early afternoon. Later this afternoon, winds gradually become much lighter as high pressure builds into the area.
