KEY MESSAGES

Updated at 1141 AM CST Tue Jan 27 2026

- Freezing fog, some dense, possible tonight into Wednesday morning.

- Very cold wind chills will be possible again Friday night with below zero wind chill values.

NEAR TERM

(Today and tonight) Issued at 1141 AM CST Tue Jan 27 2026

The question of the day today will be "Who will be able to climb above freezing?" Locations where the heaviest snow occurred will have the hardest time, especially since they got a colder start to the morning. Clouds spreading across the area will also likely hinder some of the warming. Models are showing a weak cold front moving across the area later today and tonight which will also affect the temperature forecast. Despite all this, at least parts of the fa are expected to reach the mid to upper 30s this afternoon. However, there is definitely some uncertainty with the temperature forecast at any one location.

With the cold front moving through, temperatures are expected to fall into the single digits and teens tonight with the coldest temperatures expected from north central to west central OK where the deepest snowpack is located.

Models also show the possibility of fog/freezing fog developing tonight and continuing into Wednesday morning with the best chance over parts of southern OK and north TX. Some of the fog might become dense. If this occurs and with temperatures below freezing, a layer of ice could develop especially on elevated surfaces including bridges/overpasses.

SHORT TERM

(Wednesday through Thursday night) Issued at 1141 AM CST Tue Jan 27 2026

Any fog/freezing fog would likely continue through at least mid- morning but could last until mid-day Wednesday in some areas.

The gradual warm up will continue Wednesday with more, if not all of the fa, climbing above freezing. Once again the coolest spots will likely be where the snowpack still lingers, especially where the heaviest snowfall occurred.

Models show a shortwave in the NW flow moving across the southern and central Plains Wednesday night into Thursday. At the sfc, a sfc low and cold front will move across the area bringing another shot of cold air to the region. The temperature forecast on Thursday will be dependent on the timing of the cold front but some locations in at least northern OK may not make it above freezing on Thursday with warmer (highs in the 40s) temperatures expected in southern OK and western north TX.

Guidance continues to go back and forth on whether there will be any precipitation associated with this shortwave as well with some ensembles remaining dry and some showing a low chance for precipitation mainly in northern and eastern parts of the fa. If there is any precipitation, it will likely be in the form of light snow or snow flurries with currently just a 10 to 20 percent chance. Little to no snow accumulation would also be expected with any of the precipitation.

LONG TERM

(Friday through Monday) Issued at 1209 AM CST Tue Jan 27 2026

A lobe of that Great Lakes trough looks to dive due south on Friday across the Mississippi River Valley. With that, even colder air will funnel in Friday afternoon and last through the weekend. The 12Z ECMWF was notable for having a 1046 mb high directly over central Oklahoma (EPS ensemble mean is around 1042). With those sort of surface pressures, we could see very, very cold temperatures Saturday morning anywhere that snow remains on the ground.

As the old saying goes, "This too shall pass". Our foray into a northern-plains-style winter will come to an end sometime next week. NBM suggest temperatures returning to around normal as early as Monday which would track with re-amplification of the subtropical ridge. It's possible that we end up delaying the start of that warmup another day or two into the beginning of February, though.

AVIATION

(18Z TAFS) Issued at 1133 AM CST Tue Jan 27 2026

Light southwest winds shift northerly this afternoon with variable winds possible overnight. LIFR/IFR conditions, along with freezing fog, are possible late tonight through mid-morning along and east of a line from near Wichita Falls to Lawton to OKC to Stillwater. Greatest chances of dense freezing fog are across parts of south/southeastern Oklahoma and a part of western north Texas. Light winds will shift southwesterly by mid-day Wednesday with gradually improving conditions.
