Marquette, MI – A powerful Thanksgiving winter storm is bringing dangerous travel conditions to the Upper Peninsula today as rain transitions to heavy snow from west to east, according to the National Weather Service (NWS) in Marquette. Forecasters warn that the western U.P. will see the most severe impacts, including blizzard conditions, whiteouts, and snowfall totals approaching two feet in some areas.
According to the NWS, snowfall rates of 1 to 2 inches per hour will continue through tonight across the western half of the peninsula, especially in higher terrain near Lake Superior. Widespread totals of 14–23 inches are forecast from Ironwood to Ontonagon, with localized higher amounts possible.
Strong northwest winds gusting 45 to 55 mph will combine with the heavy snowfall, creating significant visibility reductions and dangerous travel. Power outages and downed trees are also possible, particularly in exposed areas.
Farther east, central and eastern U.P. counties will see rain change to snow throughout the day, with snowfall rates up to 1 inch per hour as the system spreads eastward. Travel conditions will deteriorate this afternoon and evening as winds strengthen and temperatures fall.
System snow will gradually diminish tonight; however, moderate lake-effect snow is expected to continue into Thursday for northwest wind snowbelts along Lake Superior. Areas such as Houghton, Hancock, L’Anse, and portions of Marquette County may experience persistent snow showers and additional accumulation.
Forecasters urge travelers to avoid unnecessary travel across the western U.P. today and to use extreme caution if driving near Lake Superior where whiteouts are likely. Updated forecasts and hazard maps are expected throughout the day as the storm evolves.
