KEY MESSAGES

- A brief warmup is expected Monday into Tuesday, with highs in the 30s and 40s on Monday, rising another 10-15 degrees on Tuesday.

- Precipitation chances increase late Wednesday into Thursday (25-50%), followed by a return to cooler conditions by the end of the workweek.

WEDNESDAY, THURSDAY, and FRIDAY

Wednesday will be cooler than the two previous days. The stalled front in the area is responsible for 30-40% PoPs of light snow. This 'stationary' front is progged to oscillate north and south over the course of Wednesday and Thursday... leaving temp forecasts with plenty of uncertainty this far out.

Global models continue to insist on depicting another arctic cold front on Friday. If the forecast validates, it would mean a Saturday and Sunday morning of single digit lows. It's quite early in the season, but Omaha has already found itself in the 'severe' category of the "accumulated winter season severity index". These cold air outbreaks won't be helping.

AVIATION /18Z TAFS THROUGH 18Z TUESDAY/

Issued at 1058 AM CST Mon Dec 8 2025

IFR cigs have socked in across eastern Nebraska and are impacting all the terminals this morning. These will be slow to clear, but we should see gradual clearing from west to east. KOFK looks like will clear here around 19-20Z, while KOMA and KLNK probably won't clear until 20-22Z. Once we see VFR conditions return, they should remain through the rest of the evening with winds generally out of the south or southwest. Model guidance isn't showing it just yet, but with melting snow today leading to plenty of low-level moisture and weakening winds this evening, wouldn't be surprised if we saw significant areas of fog develop overnight tonight. If fog does impact the terminals (30% chance at this time), it would likely be around 10-15Z Tuesday as high clouds moving in overnight could help to hold it off until early Tuesday morning.
