Cold temperatures and wind are expected to combine for bitterly cold 25-35 degree below wind chills over much of northern Minnesota Wednesday, Jan. 8.
“We also expect wind chills to drop to 25 below to 35 below zero tonight into Wednesday morning over much of northern Minnesota,” the National Weather Service in Duluth reported Tuesday. “Wind chills will be the coldest midnight through 9 a.m. Wednesday. At these values, it can take just 15-30 minutes or less for frostbite to develop on exposed skin.”
The wind chill advisory is in effect from 9 p.m. Tuesday to 10 a.m. Wednesday with a northwest wind of 5 to 15 mph and gusts as high as 20 mph.
The air temperature may not rise above 8 degrees Wednesday after an overnight low of 12 below.
The weather service described wind chill as “how the wind and cold feel on exposed skin. Wind and cold combined carry heat away from the body, which can cause frostbite and/or hypothermia.”
More snow is expected late Wednesday into Thursday but higher amounts are expected along the North Shore with most of Cass, all of Crow Wing, Aitkin, Todd, Wadena, Morrison and Mille Lacs counties potentially getting less than an inch. A winter storm watch is in effect Wednesday night into Thursday for the Arrowhead portion of the state, including the North Shore. The weather service forecast noted the Grand Marais area may get the highest snowfall totals, potentially 6-8 inches with this winter storm. Grand Rapids and Duluth may receive 1-2 inches of snow with more snow possible farther north along the Canadian border.
Snow may begin Wednesday evening with the worst conditions expected late Wednesday into Thursday morning. Snowfall is predicted to end late Thursday.
Patchy freezing drizzle is also possible in spots across the Northland Thursday. The forecast calls for a temperature rebound to a high of 28 degrees Thursday and a slight — or 30% — chance for snow after 3 a.m. Expect breezy conditions to continue. The forecast calls for a slight chance of snow before 2 p.m. Thursday followed by a slight chance — at 20% — for snow and freezing drizzle.
The weather service reports the rest of the week, the coming weekend into early next week should have colder temperatures with highs ranging from about 6-18 degrees and lows from 1 degree to 10 degrees. With a stretch of days predicting clouds, Saturday stands out for the potential for mostly sunny skies.
Cold weather safety tips include
Minimize exposure — avoid exposure during the coldest wind chills.
Stay dry — wet clothing causes body heat to be lost faster. Wear waterproof, insulated boots.
Stay covered — wear a hat and gloves or mittens. At least half of a person’s body heat is lost if their head is uncovered.
Dress in layers — trapped air between layers helps to insulate.
