We will follow this up with even colder conditions and an extended period of time where temperatures don't climb above zero.
Tonight snow will continue and be heavy at times with amounts of 10 cm. Monday could be the most significant snowfall with widespread accumulation. Some locations roughly along and north of Highway 16 could receive up to 2 inches of snow before all said and done. A wind chill of 57 below was reported at the Grand Marais airport.
According to FOX 9 Chief Meteorologist Ian Leonard, some of the coldest temperatures in years are expected Tuesday through Thursday.
With the cold front moving on east, gusty west to northwest winds will bring increasingly colder Arctic-source air into the Midwest and Great Lakes. The worst of the cold is expected Thursday morning, when temperatures of -10 are forecast.
You can see from the graphic, the actual temperature has the potential to get as low as -31 on Wednesday night. This could cause headaches on the roads Tuesday as anything that does fall will freeze as temperatures plummet into the teens and 20s. Wind chills as low as 45 below zero expected. Wind: S 10 miles per hour. The wind will decrease by sunrise Tuesday, but wind chill values will still be down around 20° most of the morning. Chance of precipitation is 100%.
Regardless of where you live, much of the country is expecting to feel what could be record-setting lows this week. Actual low temperatures could drop to -30 degrees with wind chills dropping to -50 degrees. Thursday will be slightly warmer, but highs will still be below zero. West wind around 15 miles per hour, with gusts as high as 25 miles per hour. Wind: S 10-15 miles per hour. Low: 31. High: 53.
Snow showers are likely Sunday.
Saturday: Morning flurries, mostly cloudy.
