KEY MESSAGES

Updated at 109 AM CST Mon Dec 29 2025

- Cold wind chills in the single digits and teens this morning.

- Elevated fire weather conditions expected this afternoon across the west (and potentially Tuesday) due to low humidity.

- Above normal temperatures and dry conditions expected midweek though the weekend.

NEAR TERM

(Through Monday) Issued at 109 AM CST Mon Dec 29 2025

Cold air continues to stream into the area as a 1040 mb surface high across the northern Plains maintains northerly winds across the region. Temperatures have dropped into the upper teens and twenties, with wind chills in the single digits and teens. Highs today will rebound into the 30s and 40s, but a continued northerly breeze will keep it feeling chilly through the day. The northerly winds combined with dry air will also lead to elevated fire conditions once again across western OK and western north TX.

By tonight the surface ridge axis will move overhead allowing winds to become light and variable. Combined with very dry air and clearing skies, excellent radiational cooling conditions are expected. Lows tonight will drop into the teens in many locations, with low teens possible in the typically colder, sheltered areas.

SHORT TERM

(Monday night through Wednesday night) Issued at 109 AM CST Mon Dec 29 2025

The surface high will move eastward by Tuesday, bringing a return of southerly winds and a rebound in temperatures along with it. Highs will return to the 50s Tuesday, with 50s and some 60s by Wednesday. Will have to watch for the potential for elevated fire conditions Tuesday as a very dry airmass remains, but winds are expected to be much lighter which should temper the risk somewhat.

Ware

LONG TERM

(Thursday through Sunday) Issued at 109 AM CST Mon Dec 29 2025

In general, above normal temperatures and dry conditions are expected to continue through the rest of the week into the weekend as mid-upper level flow remains northwesterly or westerly. A weak shortwave will cross the area Thursday night into Friday with the associated surface low expected to traverse northern TX and southern OK. No significant airmass change is expected behind this system as winds quickly return to southerly. A more significant warmup may then be in store by Sunday as southerly flow strengthens and upper ridging builds into the area from the west.

AVIATION

(12Z TAFS) Issued at 551 AM CST Mon Dec 29 2025

Added non-convective low-level wind shear to the TAFs for early this morning. Radar VWPs were not sampling well this morning and of course the old wind profiler network is long gone, so it was not clear how strong the winds actually were above the surface. One of the first ACARS profiles this morning into OKC shows the winds are quite strong above the surface and low-level winds have decoupled/decreased enough overnight that we likely do have enough low-level shear to include in the TAFs this morning. This will likely continue until 14Z-15Z when mixing and surface winds increase to allow the shear to decrease.

Otherwise, we do expected gusty north surface winds through the day before winds become light around sunset. VFR conditions are expected with mainly high clouds expected over the area.
