      Another dangerously cold night for Upper Michigan tonight

      Strong northwest winds become more westerly Monday evening as a ridge of high pressure slides just south of our area. Lake effect snow showers gradually diminish Monday afternoon and evening across most of Upper Michigan. However, we still expect a few showers to linger over the northern Keweenaw Peninsula and our Superior shoreline near Grand Marais into Monday night.

      Overnight lows fall into the teens and 20s below zero across much of the area with the coldest readings over the typical cold spots of the interior west. Breezy westerly winds keep wind chill readings in the -35 to -45 range by early Tuesday morning. Similar to Monday morning, exposed skin will succumb to the effects of frostbite within ten to twenty minutes Monday night/Tuesday morning. A Wind Chill Warning remains in effect until 1 p.m. EST for west and central Upper Michigan.

      Tuesday, we expect any lingering snow showers to be limited to northern Keweenaw Peninsula and the Lake Superior shoreline east of Marquette. Daytime highs will be centered around zero under partly cloudy skies.

      Tuesday night/Wednesday morning will be bitter cold with wind chill readings in the -25 to -35 range. Otherwise, expect increasing afternoon clouds and breezy southwest winds ahead of the next clipper crossing south/central Canada. Scattered light snow showers move in Wednesday night, lingering into a good part of the day on Thursday.

      Temperatures slowly moderate, reaching into the mid teens through the second half of the work week. Overnight lows will still dip into the single digits below zero through the six-day forecast. Lake effect snow showers will hang around roughly the northern half of Upper Michigan Thursday though the weekend.

      Temperatures are expected to stay below normal well into February. Great Lakes ice continues to peak our interest. These below normal temperatures should eventually bring an impressive ice buildup into February. However, strong winds can wreak havoc on solid ice pack. Last time we checked, there was plenty of open water on the big lake. And so we continue to see nuisance lake effect snow near our Superior shoreline.
