WISCONSIN - An early winter storm will have major impacts on pre-Thanksgiving travel across the region, including Wisconsin. The storm will begin tonight with snow becoming heavy overnight into Wednesday morning. Strong winds could also lead to flight delays and difficult driving conditions across Wisconsin, Illinois, Indiana, and Michigan. See below for details!
The storm will move in tonight mainly after 6PM, though rain could fall across southern and central areas before that. Heavy snow develops after 9PM in the northwest towards Minneapolis. Overnight heavy snow will fall from southern Minnesota through northwest Wisconsin. Upper Michigan will see most of the snow on Wednesday morning with snow continuing into Wednesday night in the lake effect regions near Lake Superior.
Start and end times for storm snow/rain. Please note that there will be different precip types from one end of Wisconsin to the other. Also the wind gusts will remain strong into Wednesday evening.
A heavy snow band of 8-12" is expected from Minneapolis to Hayward to Manitowish Waters. 12"-18" is likely across the lake effect snow regions of upper Michigan and far northern Wisconsin including Ashland, Ontonagon, the Keweenaw Penisula and Marquette. For central Wisconsin a gradient in snow accumulation will occur as warmer temps and a dry slot push towards Rochester, Wausau/Merrill, and Escanaba. No snow accumulation is predicted for southern Wisconsin however flurries may fly during the day Wednesday.
Low pressure center will track straight through Wisconsin which tends to bring a period of weaker wind gusts during the peak of the event. For Wisconsin as a whole the strongest wind gusts will be on Wednesday during the day and evening as the storm pulls away, possibly gusts to 40-45 mph out of the northwest. Otherwise strong winds gusts will impact the entire region with the highest gusts across Illinois, Indiana, and Michigan.
RAINFALL, TRAVEL HAZARDS, and MORE
Rainfall amouts could reach 1" in far eastern/northeastern Wisconsin, locations such as Door county over towards Marinette. With the dry slot pushing in lower rainfall amounts less that 0.5" for most of southern Wisconsin.
Travel on Wednesday morning is not recommended across northwest Wisconsin. I would wait until later in the day if possible.
