Arctic Blast Brings Severe Cold Across Northern US

A severe cold snap is affecting multiple states in the Midwest, with wind chills expected to plunge to -30 degrees Fahrenheit or lower in regions of North Dakota, Montana, and Minnesota, prompting warnings from the National Weather Service about potential frostbite and hypothermia. Northern Minnesota is under a cold weather advisory, with temperatures staying 10-15 degrees below normal and wind chills reaching around 30 degrees below zero. In the Upper Peninsula of Michigan, lake effect snow showers are forecasted, particularly in the Keweenaw Peninsula, with gusty winds enhancing the chill. Springfield, Illinois, is preparing for a mix of freezing rain and snow this weekend, which could lead to hazardous conditions and a possible flash freeze. The frigid temperatures are expected to persist into next week, with many areas experiencing highs in the lower 20s and lows in the single digits. Residents are advised to limit outdoor exposure and be prepared for rapidly changing weather conditions.
