KEY MESSAGES

Updated at 1241 AM CST Sat Jan 31 2026

- Below-zero wind chills this morning across much of Oklahoma.

- Moderating back to near or slightly above normal temperatures for much of next week.

NEAR TERM

(Through Saturday) Issued at 1241 AM CST Sat Jan 31 2026

The cold temperatures are back. The reinforcing surge of cold air has moved into the state along with gusty winds. The wind chill temperatures is already below -5 F across north central Oklahoma, and much of Oklahoma will see minimum wind chill values below zero this morning. Farther south across north Texas, minimum wind chill values are expected to be between zero and +5 F this morning.

Some radar echoes persist from northwest Oklahoma toward south central Oklahoma. Much of this is virga, but expect to see a few flurries reach the ground over the next couple of hours. These echoes and flurries should diminish through the early morning hours.

Winds will diminish later this morning as the 1043+ mb surface high moves into Oklahoma. As the surface high continues to move southeast, southerly winds will develop across western Oklahoma and western north Texas this afternoon on the west side of the high.

SHORT TERM

(Saturday night through Monday night) Issued at 1241 AM CST Sat Jan 31 2026

The cold temperatures with this airmass will be short-lived. Low temperatures Sunday morning will be warmer than this morning, but still generally in the teens and cooler than normal. But it will feel much different Sunday afternoon with high temperatures 15 to 25 degrees warmer than Saturday. Monday will be even warmer with highs in the 50s and 60s.

There is a hint in the operational models of some very light QPF Sunday morning as a shortwave moves over the area in the northwesterly flow aloft. But the signal is not strong and do not believe the potential is sufficient to introduce POPs at this time.

LONG TERM

(Tuesday through Friday) Issued at 1241 AM CST Sat Jan 31 2026

Monday night and Tuesday, an upper wave amplifies in the central Plains in the northwesterly flow aloft. This will bring another front into the area cooling temperatures a bit Tuesday and Wednesday, although not as cold as our current airmass. Models continue to weaken the trend of potential precipitation in our area with this front with mentionable POPs now confined to portions of Atoka and Bryan Counties on Tuesday within our forecast area.

Wednesday will be the coolest day of the work week as the surface ridge moves into Oklahoma and north Texas, but then temperatures warm to much above normal late in the week as an upper-level ridge redevelops to the west and the cold air shifts to the eastern U.S.

AVIATION

(06Z TAFS) Issued at 1009 PM CST Fri Jan 30 2026

Low clouds will begin to clear and lift late tonight with a return to VFR ceilings by the early morning hours. There is a low potential for additional light snow and flurries past midnight. A surface high will push south across Oklahoma tomorrow returning winds to the south through the day.
