KEY MESSAGES

Updated at 1150 AM CST Sun Dec 28 2025

- Wind chills expected to drop into the single digits and teens overnight.

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

NEAR TERM

(Today and tonight) Issued at 1142 AM CST Sun Dec 28 2025

Cold front continues to push through southeast Oklahoma this afternoon with falling temperatures and very windy conditions behind the front. Even with falling temperatures, the combination of strong gusty north winds and dormant vegetation will raise the fire weather concerns into the elevated category through sunset.

Winds will gradually decrease this evening as cold surface high settles south through the Plains. Although there will be some high clouds overnight, the combination of some weaker caa and sufficient breaks in the clouds, temperatures will drop into the 20s across Oklahoma and western north Texas by Monday morning. Winds will remain in the 10-15 mph range through the early morning hours which will put the wind chills in the teens across most of the area.

SHORT TERM

(Monday through Tuesday night) Issued at 1142 AM CST Sun Dec 28 2025

Surface ridge axis moves slowly east through the Plains Monday with lighter north winds, but cold conditions. Temperatures will struggle to warm with 30s for highs across the northeast half of the area with low/mid 40s farther south and west. Surface dewpoints will also be very low in this airmass with dewpoints in the single digits to perhaps below zero across the west. Even with the much colder temperatures and rather modest wind speeds, the daytime RH values are expected to drop into the 15-20% range across the west Monday afternoon. This will again result in a period of elevated fire weather conditions across western Oklahoma and western north Texas.

Surface high will settle overhead Monday night with another cold night expected. Temperatures will again fall into the teens and 20s by Tuesday morning.

South/southwest winds return Tuesday, which will bring in warmer air off the higher terrain to our west. Should see temperatures respond, climbing into the 50s. Could again see some elevated fire weather conditions develop as afternoon humidity values fall below 20%.

LONG TERM

(Wednesday through Saturday) Issued at 1249 AM CST Sun Dec 28 2025

A return to much above normal temperatures (though not as warm as the past several days) is expected mid to late week as upper ridging across the western US builds eastward and westerly/northwesterly flow aloft is maintained over the region. One potential caveat is a weak shortwave that is forecast to cross the area on Friday which, depending on the track of the attendant surface low, may pull cooler air into the area from the north. Unsurprisingly, models show a wide range in forecast highs Friday, with NBM 10th-90th percentile spreads of 20-30 degrees in many locations. As far as precipitation chances, the vast majority of guidance keeps us dry through next weekend, though about 20% of models currently show a chance for rain accompanying the Friday system.

AVIATION
