KEY MESSAGES

Updated at 511 AM CST Tue Jan 27 2026

- Very cold wind chills will continue into Tuesday morning with wind chills below zero in spots.

- Freezing fog possible on Tuesday night, dense fog possible on Wednesday night.

NEAR TERM

(Through Tuesday) Issued at 1209 AM CST Tue Jan 27 2026

We are sitting at 80-90 consecutive hours below freezing and the main question today will be how many of us end that streak. Temperatures this morning won't be quite as cold as they have been the last few days because of a light breeze, though that does mean wind chills will again range from near to ten below zero.

Another deep trough will dive southeastward into the Great Lakes with northwest flow over the Plains today, so a weak frontal boundary will develop and slowly drift southward. Despite this, plentiful sunshine is expected and most of the area should reach or exceed 32 for high temperatures. Right now, the likeliest areas to remain below freezing are close to and just northwest of I-44 where the snowpack is deepest. Otherwise, temps should get into the mid-to- upper 30s.

SHORT TERM

(Tuesday night through Thursday night) Issued at 1209 AM CST Tue Jan 27 2026

The impact of sunshine and near-freezing temperatures should lead a deal of melting snow, which will in turn make conditions more favorable for fog/freezing fog development tonight. The likeliest spot for that freezing fog will be near and just south of the weak frontal boundary in a zone that will encompass southern Oklahoma and parts of western north Texas.

As a trough approaches the Front Range during the day on Wednesday, a weak surface low pressure should develop to our west. That will bring temperatures up a few degrees from today and eat further into the snowpack. Southerly winds and melting snow are often a catalyst for even more fog development, so Wednesday afternoon and especially Wednesday night will be watched for potentially widespread dense fog.

Wednesday afternoon will likely prove the high point of the week temperature-wise, as a stronger cold front will arrive on Thursday. Super-ensemble guidance is extremely mixed on whether or not this will be a dry frontal passage. The Canadian ensemble and GEFS both show a 40-70 percent chance of at least light precip across northern Oklahoma, while the EPS outright fails to produce precipitation. This looks like a target of opportunity for future forecast cycles to nail down any potential precipitation. Highs on Thursday will be dependent on the front's location in the afternoon, with spots north of I-40 potentially remaining sub-freezing.

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

(12Z TAFS) Issued at 511 AM CST Tue Jan 27 2026

Light southwest winds will shift to northerly during the day. Toward the end of the TAF period, stratus and freezing fog are expected to develop in south central Oklahoma and north Texas. How far northwest this pushes is somewhat uncertain with chances falling off somewhere around the I-44 corridor.
