- Hazardously cold conditions are forecast through Monday morning.

..Hazardously cold conditions tonight through Monday morning

Chose to extend the Extreme Cold Warning within northwest MN based on high probabilities greater than 80% of wind chills -40F or colder within the REFS and HREF guidance suites. Despite clouds moving into the region later tonight, there is relatively high confidence in temperatures dropping well into the twenties below zero in northwest MN considering temperatures heading into tonight well into the teens below zero. These temperatures combine with an increasing breeze out of the southwest as pressure gradient starts to tighten ahead of an approaching weak shortwave trough.

The combination of temperatures into the twenties below zero and a breeze building out of the southwest will drive wind chill values well into the 40s below zero through Monday morning. Elsewhere, there is high confidence in wind chills between 30 to 40 below zero tonight through Monday morning.

AVIATION /18Z TAFS THROUGH 18Z MONDAY/

Issued at 334 PM CST Sun Jan 25 2026

Main potential impact to aviation within the TAF period through 18Z Monday is low level wind shear. After 12Z, low level winds increase out of the southwest between 40-50kt, introducing LLWS at sites like KDVL, KFAR, and KBJI.

Winds at the surface will remain light between 5-10kt shifting from northerly to westerly then southwesterly. When turning southwesterly, winds increase between 10-20kt, gusting to 27kt at KDVL.

Otherwise, clear skies eventually give way to high altitude clouds after 09Z, still remaining VFR.

After 18Z Monday, light snow and shifting winds out of the north enter the forecast at several sites. This may bring lowered ceilings and reduced visibility from light snow, generally between VFR to MVFR.
