DISCUSSION

Issued at 401 AM CST Wed Dec 3 2025

A cold front has entered the northern part of the Omaha CWA this morning, bringing with it much colder air. Ahead of the front, there is a very small chance (5-10%) of some patchy drizzle/freezing drizzle through around sunrise. Otherwise, flurries will be possible across the region this morning, gradually tapering off from northwest to southeast by early afternoon. Little to no accumulation is expected with this system as it moves through. Noticeably colder air will move into the region today, dropping temperatures through the course of the day.

Heading into tonight, bitterly cold temperatures are expected as colder air moves in, skies clear out, and winds die down. Low temperatures Thursday morning will be below zero in most locations, with some areas falling to around or colder than -10F. Wind chill values will range from 0 to -10 for areas along and south of a line from Lincoln to Clarinda, and -10 to -20 for areas north.

Thursday, a ridge inches closer to the West Coast, with northwest flow setting up over the region. The cold will remain in the region, with expected highs in the teens for western Iowa and the teens and 20s for eastern Nebraska. Conditions warm up slightly on Friday and Saturday as highs return to the 30s.

Saturday morning, a mid-level shortwave trough will drop into the region. Areas north of the Platte River may get clipped with a little bit of snow Saturday morning through Sunday morning. At this time, little to no accumulation is expected; however, continue to monitor the forecast for changes in the coming days.

Monday through the extended forecast, models continue to show the ridge over the West Coast shifting east, bringing a gradual warming trend to near normal.

AVIATION /06Z TAFS THROUGH 06Z THURSDAY/

Issued at 1020 PM CST Tue Dec 2 2025

MVFR cigs have started to move into northeast Nebraska and KOFK this evening as the cold front moves in. Along with the front comes a shift to north-northwesterly winds. This will continue to spread southeastward overnight with a period of flurries or freezing drizzle possible (15-20% chance) for a few hours after the front moves through. Expect MVFR cigs to hang around through much of the day on Wednesday, likely clearing towards 22-00Z. Once cigs clear, we'll see VFR conditions through the rest of the TAF period.
