Very cold in the Northland at 7AM this morning. Yes the map shows air temperatures not wind chill temperatures. Kabetogama General Store just reported -49. Thanks to all of our NWS Cooperative Observers. #mnwx #wiwx pic.twitter.com/CeXR3GMQcv— NWS Duluth (@NWSduluth) January 27, 2019
Wind chill reports included 57 below zero at the Grand Marais airport, 54 below at International Falls and 51 below at the Grand Marais harbor.
The cold is just getting started, as another shot of arctic air is forecast to sweep across the state for Tuesday, Wednesday and Thursday. Lows may reach the 20s below zero — or lower — across all of Minnesota by midweek, with highs remaining below zero. West-northwest winds will make it feel even colder.
