KEY MESSAGES

- Hazardously cold conditions are forecast tonight through Monday morning.

UPDATE

Issued at 535 PM CST Sat Jan 24 2026

Still seeing scattered reports of light snow reaching the ground across the area this evening. A dusting of accumulation is possible but given light winds the wind chills tonight remain a much higher relative impact and the novelty flurries can largely be disregarded.

..Hazardously cold conditions tonight through Monday morning

We are currently in a brief reprieve in hazardously cold conditions. This changes tonight as winds increase and temperatures decrease behind a cold front and arctic air mass moving through the region. Wind chills between 40 and 50 below zero are forecast generally along and north of Highway 200 corridor tonight through Sunday morning.

Latest guidance from both 12Z HREF and 12Z REFS show probability for -40F is less than 50% along and south of I-94 corridor. With this in mind, opted to convert portion of the Extreme Cold Warning to Cold Weather Advisory along I-94 corridor. We could still see some locations just touching -40F at times Sunday morning within the southern Red River Valley, but still opting to retain the Extreme Cold Warning for locations that have higher chance at seeing wind chills deeper into the 40s below zero more consistently/widespread.

The chance for additional 40 below zero wind chills decreases below 50% after Sunday morning, although a few areas could briefly reach into the low 40s below zero Monday morning outside of the Red River Valley.

AVIATION /00Z TAFS THROUGH 00Z MONDAY/

Issued at 535 PM CST Sat Jan 24 2026

Patchy MVFR conditions are plausible at all sites through the next 12 hours as low clouds associated with some light snow will work through overnight. Winds turning from the current southerly to northerly with the passing of this wave and pick up slightly for tomorrow afternoon at 8-13kts through VFR conditions after 12z will be likely once again. Periodic vis reductions to 4-5SM are possible but are unlikely to prevail for multiple hours on end at any given terminal.
