Plunging temperatures in Minnesota are making snow removal a bit tricky as fluffy precipitation turns to rock hard ice.
City crews in Duluth scrambled to clear streets before the deep freeze Thursday. Schools are canceling classes again in Duluth, Superior, Wis., and other cities in the region.
Forecasters expect the daytime temperature Thursday will reach 13, but just 4 below on Saturday.
A National Weather Service observer recorded 42 inches of snow just north of Two Harbors. Spotter Alice Findley uses a neon pink yardstick to measure the snow for the weather service. Findley lives on a big hill where the lake effect usually delivers a bit more snow. Findley tells the Duluth News Tribune she took several measurements around her yard and the snow was deeper than her yardstick in all locations.
Plenty of people will be out shoveling snow today, and the cold that’s moved in has made that snow much heavier and even icy.
Doctors say this kind of snow needs to be shoveled with caution because it can be really hard on your heart.
