KEY MESSAGES

Updated at 1155 AM CST Tue Nov 25 2025

- Cool and dry weather through Friday.

- Strong cold front arrives this weekend with below-normal temperatures likely and a low chance for wintry precipitation into early next week.

NEAR TERM

(Today and tonight) Issued at 1155 AM CST Tue Nov 25 2025

As a shortwave trough moves eastward across the Northern Plains, a trailing cold front is advancing to the southeast across Oklahoma and north Texas this afternoon.

Vertical mixing into modest 925 to 850 mb flow (25 to 30 knots) is resulting in gusty northwest winds at 25 to 35 mph behind the cold front. Toward the latter part of the afternoon, cold air advection will be significant enough where temperatures will become steady and even begin to fall--especially across northwest Oklahoma.

The cold front will move through the entire area by late this afternoon. Drier air is also advecting behind front with dew points dropping into the 30s and eventually the 20s deg F.

By tonight, winds will gradually decrease as a surface high moves to the southeast toward the Southern Plains. Low temperatures tonight will range from the mid 20s to upper 30s deg with the drier air mass in place.

SHORT TERM

(Wednesday through Thursday night) Issued at 1155 AM CST Tue Nov 25 2025

Cool, slightly below-normal temperatures are expected on Wednesday with the surface high centered across Oklahoma and north Texas. High temperatures will range from the upper 40s to the mid 50s deg F. As the surface high passes by, winds will shift toward the south by late afternoon into the evening. With a dry air mass still in place, most locations will likely drop to near or below freezing Wednesday night into Thursday morning.

By Thanksgiving Day, the return to southerly winds will result in seasonable temperatures with highs in the 50s and 60s deg F. Abundant sunshine and light winds should make for a perfect Thanksgiving Day.

LONG TERM

(Friday through Monday) Issued at 1203 AM CST Tue Nov 25 2025

Synoptic uncertainty increases as we get to late week. Models depict a shortwave moving through the central CONUS on Saturday (high variance in timing, depth, and north-south position), with warm air advection starting up ahead of this feature. With the WAA, we'll see rain chances increase Friday night through Saturday, particularly over southeastern Oklahoma.

Interquartile ranges for temperatures Saturday night and Sunday approach 20-30 degrees, largely due to significant timing differences (24-48 hours) in the arrival of a strong cold front. This will also impact continuing precipitation chances early next week as well as precipitation type. Currently, ensemble guidance suggests 10-20% chance of wintry precipitation across the northwest half of Oklahoma.

Day

AVIATION

(06Z TAFS) Issued at 1042 PM CST Tue Nov 25 2025

VFR conditions are expected over the next 24 hours although there increasing mid-level cloudiness is expected. North winds tonight will become light as the area of high pressure at the surface moves into the Southern Plains, with winds becoming southerly across the western TAF sites late on Wednesday.
