DISCUSSION

Today:

Water vapor imagery this morning features the deep system that brought yesterday's winter weather continuing to sweep across the eastern half of the CONUS, with bitterly cold air pouring in from the north behind it. Though the surface pressure gradient is decreasing, gusty winds of 30-40 mph have continued into the early morning hours, with similar gusts out of the northwest holding on through noon before gradually diminishing going into the afternoon/evening. Before they diminish, they'll be contribute to very cold wind chills this morning of 10 to 19 degrees below that will only improve to the single digits this afternoon. In addition to the cold, steep low-level lapse rates have helped areas of shallow flurries develop and waft southeast across the forecast area. These should only last through 6-8 AM before scooting off to the east. After temperatures peak in the 20s, we'll be set for another cold, but not as cold night heading into Tuesday.

Tuesday and Beyond:

The rest of the forecast quiets down significantly with the departure of yesterday's system, with the mid/upper pattern transitioning into a split-flow pattern with dual northwesterly jet streaks stemming from a ridge axis over the Intermountain West. Global deterministic models are in good agreement that this pattern will hold through the work week, before transitioning to quasi- zonal mid/upper flow heading into the weekend. A clipper system will miss the area to the northeast Wednesday, before another system ejects across the Southern Plains Friday, dodging us to the south. Temperature-wise, highs will rebound quickly Tuesday and Wednesday into the 40s (and even 50s in south-central Nebraska), trend back down into the 30s Thursday/Friday once the clipper system's front sweeps through, and slowly warm heading into the weekend. Fortunately we are getting all of the strong winds out of the way now, with seeming quiescent speeds limiting any bite to the air through the week.

AVIATION /12Z TAFS THROUGH 12Z TUESDAY/

Issued at 527 AM CST Mon Dec 29 2025

MVFR ceilings will be the main thing to watch for, with a patch of clouds wafting towards KOFK/KLNK and bringing off-and-on restrictions through 14z and VFR conditions thereafter. Otherwise, winds that are gusting near 30 kts will continue slowing down over the course of the morning/early afternoon, with gusts falling off by 00z this evening. Overnight, winds will become light at less than 10 kts and become southwesterly heading into the morning hours.
