Fargo, North Dakota – Eastern North Dakota and eastern South Dakota are settling into a prolonged and punishing stretch of Arctic cold that will dominate the region from late January into early February, with little indication of meaningful relief before Valentine’s Day. From the Red River Valley to the open plains east of the James River, subzero temperatures and dangerous wind chills are expected to remain a daily reality.
According to the National Weather Service Climate Prediction Center, temperature outlooks from January 23 through February 13 strongly favor well below-normal temperatures across the northern Plains. Multiple outlook periods continue to show Arctic air repeatedly reinforcing itself over the region, keeping extreme cold locked in place as February begins.
In Fargo and Moorhead, daytime highs may struggle to climb above zero during the coldest stretches, while overnight lows frequently plunge well below zero. Wind chills along I-29, I-94, and exposed areas near the Red River may reach dangerous levels capable of causing frostbite in minutes. Grand Forks and the northern Red River Valley are likely to see even colder conditions, with extended periods of subzero air temperatures stressing vehicles, homes, and utilities.
Across eastern South Dakota, including Aberdeen, Watertown, Brookings, and Sioux Falls, Arctic cold will remain firmly entrenched. Daytime highs may stay in the single digits or teens at best, with overnight lows dropping sharply below zero, especially during clear, calm nights. Gusty winds sweeping across open farmland and along I-29 will further amplify wind chill dangers, particularly during early morning and overnight hours.
The prolonged cold creates serious risks for frostbite, hypothermia, frozen pipes, and power disruptions. Residents are urged to limit outdoor exposure, dress in insulated layers, ensure heating systems are functioning safely, and bring pets indoors. Drivers should carry winter survival kits, especially when traveling rural highways where help may be delayed.
While brief moderation is possible at times, long-range signals suggest the Arctic grip across the eastern Dakotas may not loosen in a meaningful way until after Valentine’s Day. Additional cold weather advisories or warnings remain likely as this extreme winter pattern continues across the region.
