Grand Forks, North Dakota – An extremely cold air mass is expected to move into eastern North Dakota and northwest Minnesota after midweek snow, bringing potentially dangerous wind chills through the end of the week.
According to the National Weather Service in Grand Forks, snow and blowing snow on Wednesday will be followed by a surge of Arctic air Wednesday night. Forecast guidance shows a high probability of apparent temperatures dropping to -40°F or colder, with bitterly cold conditions continuing through Friday and into the weekend.
NWS probability graphics indicate elevated chances of -40°F wind chills across the Red River Valley, including areas near Grand Forks, Fargo, Devils Lake, and Bemidji. These conditions are considered potentially life-threatening, with officials warning that frostbite on exposed skin can occur in as little as five minutes. Prolonged exposure could also lead to hypothermia if precautions are not taken.
The cold outbreak is expected to follow accumulating snow and periods of blowing snow, which may further complicate travel and outdoor activity. Confidence is high that this will be one of the coldest stretches of the season for the region.
Residents are urged to limit time outdoors, dress in multiple layers, and ensure pets and livestock have adequate shelter from the cold. Vehicles should be winter-ready, and those who must travel should carry emergency supplies. Young workers, students, and commuters should plan for cold-related delays and safety risks during early morning and overnight hours.
The National Weather Service advises closely monitoring updated forecasts and wind chill advisories as the Arctic air settles in.
