KEY MESSAGES

- Dangerously cold wind chills continue today through Sunday.

UPDATE

Issued at 1149 AM CST Sat Dec 13 2025

A quick update here to expire the Extreme Cold Warning on time at the top of the hour at Noon. Wind chills have improved over the past hour, with only the Langdon area still seeing -40 or colder values. Wind chills will remain very cold through the afternoon, in the -20s to -30s below zero, so this "improvement" is relative to what we saw earlier today. All other portions of the forecast remain on track.

UPDATE Issued at 938 AM CST Sat Dec 13 2025

A very cold morning across the FA, with wind chills as cold as 53 below zero in the Langdon area. Wind chills have recovered very little, with -40 values as far south as the Highway 200 corridor. With wind chill values that low, headlines remain in good shape as of mid morning. The center of high pressure responsible for the cold will approach the western FA today, which will keep temperatures subzero through the afternoon. This will set the stage for another very cold night. With the center of high pressure much closer, winds should be lighter compared to what we saw last night, keeping wind chills slightly higher. Not that it will matter much, as however you look at it, the next 24 hours are going to be very cold.

UPDATE Issued at 549 AM CST Sat Dec 13 2025

Cold and quiet conditions continue with only a few lingering clouds in our southwestern counties. Much of the extreme cold warning is below -40 or close to it. No changes planned for headlines.

..Extreme cold this weekend

Wind chills currently in the -40 to -45 range across portions of the Devils Lake Basin into the northern Red River Valley. See little reason to make changes to the extreme cold warning at this point. Southern portions of the CWA have more cloud cover and are above -30 in some places, but still plenty cold and will see a continued drop in the next few hours. HREF has high probabilities of -30 or less apparent temperatures continuing through the rest of today and into tomorrow night. Should see some improvement during the day on Sunday.

AVIATION /18Z TAFS THROUGH 18Z SUNDAY/

Issued at 1149 AM CST Sat Dec 13 2025

VFR throughout the TAF period. There are a handful of model solutions that bring a lower MVFR stratus deck back into northwestern MN. Confidence in this happening at this time is low. Therefore, kept it out of the TAFs for now. Winds should follow a general decreasing trend through this evening, becoming calm/variable overnight. Winds will pick up quite significantly for Sunday as warmer air pushes into the region. These stronger southerly winds will introduce gusts into the TAFs mid to late Sunday morning, continuing beyond this TAF period into the afternoon.
