After a widespread light powdery snow falls on Sunday into Sunday evening, expect the hazard to abruptly switch from snow to reduced visibilities and bitter cold wind chills as northwest winds increase with the arrival of arctic air. Winds will gust 30-45 mph late Sunday night into Monday. The strong winds along with fresh powdery snow will lead to blowing and drifting snow with sharply reduced visibilities, including the potential for near whiteout conditions on the Bay of Green Bay and Lake Winnebago. A Winter Weather Advisory is in effect for Door and Vilas counties due to the snow or blowing snow and poor visibilities. The strong winds and bitter cold air will result in wind chills dropping to dangerous levels of 20 to 30 below zero Monday morning, and again on Tuesday morning.
