KEY MESSAGES

Updated at 513 AM CST Thu Nov 27 2025

- Cool and dry through Friday with highs in the 50s.

- A significant cold front crosses the area Saturday, bringing falling temperatures during the afternoon and gusty north winds.

- Below normal temperatures persist into early next week, with low chances (20-30%) for wintry precipitation Monday.

NEAR TERM

(Rest of tonight through Thursday) Issued at 1157 PM CST Wed Nov 26 2025

Today we are thankful for a sunny thanksgiving with seasonably cool temperatures (50s) and light winds.

As warm air advection begins to ramp up, we'll see clouds invade from the southwest tonight with lows in the low to mid 30s.

Day

SHORT TERM

(Thursday night through Friday night) Issued at 1157 PM CST Wed Nov 26 2025

Friday and Saturday's weather will be marked by an approaching trough and associated warm air advection.

Friday's temperatures will be much like previous days, but with increasing clouds and breezy winds. Some drizzle or light showers will be possible in parts of southern Oklahoma and north Texas by afternoon, with rain chances increasing from the south overnight.

By Saturday, rain chances will have reached 60-80% over much of central and eastern Oklahoma before gradually ending west to east. Southern parts of the forecast area will see some warming due to the southerly fetch of warm, moist air while northwest Oklahoma will see highs cut off in the 40s as a strong cold front moves through. Expect falling temperatures and gusty north winds behind the front.

Precipitation should be ended by the time freezing temperatures make their way in behind the front. Saturday night will be quite cold with air temperatures dropping into the teens and 20s and wind chills into the single digits / teens.

Day

LONG TERM

(Saturday through next Wednesday) Issued at 1157 PM CST Wed Nov 26 2025

Ensemble solutions continue to come into better agreement concerning the early week synoptic setup and Sunday/Monday's potential winter weather. I'll address the two potential impacts (cold and wintry precipitation) in turn:

Cold: Confidence in very cold temperatures is high for Sunday and Monday. Ensemble guidance shows lows in the teens and 20s both mornings and highs in the 30s and 40s. It's not extreme cold, but enough of a sharp drop to be impactful.

Wintry Precipitation: Forecast is trending later with slightly reduced PoPs, keeping Sunday and Sunday evening mostly dry with precipitation chances increasing to 20-30% starting early Monday morning. Snow chances will be highest in the northwest (30% chance of 1"+), decreasing southeast. Freezing rain chances have come down to less than 10%. A reasonable worst case scenario (90th percentile) would have up to 4 inches of snow in northwest Oklahoma down to 0.5 inches along the I-44 corridor.

Tuesday, things begin to warm back up as the upper system departs. Another trough is forecast to deepen across the western US later next week, but model spread becomes quite large by this time so impacts (if any) to our area remain unclear.

Day
