NEAR TERM

(Today and tonight) Issued at 1136 AM CST Sat Jan 24 2026

A shortwave embedded in the flow has caused another area of winter precipitation to move into/across parts of the fa this morning. This activity extends west and southwestward across west TX towards the Big Bend area. Models have not had a great handle on this activity but it now appears the afternoon lull that was forecast to occur over the last few days will not be happening with periods of light to moderate precipitation through the afternoon. Meanwhile, the forecast for the heaviest and most persistent winter precipitation is still on track for this evening into early Sunday as the upper low currently over Baja opens up and moves across the region.

For this afternoon and evening, snow is expected mainly near and north of I-40. However, some sleet may mix with the snow at times along the I-40 corridor. More of a wintry mix is expected across southern OK and western north TX where snow, sleet, and freezing rain will be possible as the main upper system approaches and the warm nose continues over this area. The wintry mix is expected to eventually change over to snow later tonight across southern OK and western north TX.

As for amounts, the highest additional snowfall amounts are currently expected to be in a band from Cheyenne and Hollis to Purcell and Kingfisher to north of Stillwater and Seminole where an additional 6 to 8+ inches will be possible through Sunday. The lowest amounts of 2 to 4 inches are expected in NW OK and then across parts of southern OK and western north TX. The band of heaviest snow could shift north if the warm nose makes further northward progress than is currently expected. As for ice amounts, some locations in southern OK and north TX could see additional ice accumulations of up to around a tenth of an inch. However, this accumulations will be affected if most sleet and/or snow occurs, especially if the transition to snow occurs sooner than currently forecast.

The dangerous cold will continue today and tonight with highs mostly in the single digits and teens. Temperatures are expected to fall to around zero in NW OK with single digits across the rest of the area. Wind chills are expected to be even colder with values ranging from 5 to -10 this afternoon. Minimum wind chills tonight are expected to range from -5 to around -15.

So overall, the winter precipitation and dangerous cold continues through tonight with additional heavy precipitation expected especially this evening into early Sunday. Roads will remain slick and hazardous with travel discouraged.

SHORT TERM

(Sunday through Monday night) Issued at 1136 AM CST Sat Jan 24 2026

Snow will be ongoing Sunday morning as the upper system continues to move across the region. The snow is expected to gradually end from west/northwest to east/southeast throughout the day Sunday. However, models show another shortwave dropping in behind this system and moving across the area which could bring some light snow/snow flurries to NW parts of the fa Sunday night into early Monday. Despite the precipitation ending, slick and hazardous road conditions will likely persist into Monday.

Even though the precipitation is expected to end for the most part on Sunday the dangerous cold will continue. Highs on Sunday are expected to be in the teens with highs on Monday in the 20s. Lows Sunday night are expected to be even colder with temperatures ranging from -5 to 5 across the fa. Wind chills will continue to be a factor Sunday into Monday with minimum wind chill values Sunday night into early Monday ranging from -5 to -20. Excessive cold warning remains in effect into Monday morning.

LONG TERM

(Tuesday through next Friday) Issued at 1136 AM CST Sat Jan 24 2026

Cold temperatures will persist next week with high temperatures slowly climbing into the 30s and maybe 40s although the warm up will be much slower where higher winter precipitation amounts occur.

Some snow flurries may linger across parts of the area Monday morning as the previously mentioned shortwave continues to move across the area but overall the forecast will remain dry after Sunday night until late next week when there are some hints of light precipitation returning to parts of the area.

AVIATION

(00Z TAFS) Issued at 519 PM CST Sat Jan 24 2026

Our terminals will remain in at least a MVFR category through the entire period but further degrade to an IFR category with lowering ceilings and further reduced visibilities in moderate to heavy snow between 04-09Z when the final mid-level shortwave digs through. The precipitation type for terminal KSPS during this time period could see more of a sleet/snow mixture while terminal KDUA may see more moderate to heavy sleet. For the next 3 hours will continue to see scattered light snow under mostly IFR conditions due to restricted visibilities. After 09Z terminals expected to see scattered periods of light snow decreasing after 18Z with gradually rising ceilings. Surface winds will remain northerly around 10-15 kts.
