A mainly clear sky this evening, except right along the south shore of Lake Superior where some lake enhanced clouds will persist. Warm air advection will occur all night. A light wind this evening and the mainly clear sky will allow temps to drop fairly quickly and low wind chill values to be achieved. A Wind Chill Advisory has been issued for tonight. Surface temps begin to warm from northwest to southeast overnight, and mid and high clouds are forecast to increase over northeast Minnesota, which will limit wind chill impacts late tonight. A warm, southwest wind will cover the Northland Wednesday morning, with increasing cloud cover, will have the Wind Chill Advisory expire at 17Z/11AM. Some lake effect snow showers/flurries are possible along the north shore from the southwest wind. Some light snow or flurries are expected to develop along the Borderland from late morning into the afternoon as a cold front approaches from south central Canada. Amounts will be light, with up to one inch from Grand Marais to Grand Portage. A second cold front moves through the Northland Wednesday night ushering back in the well below normal temps. Scattered snow showers or flurries will accompany this next front. Some light accumulation is forecast.
