Duluth, MN – A wintry system arriving Tuesday will bring a mix of rain and snow to the Northland before transitioning to all snow Tuesday night and continuing through Wednesday, according to the National Weather Service in Duluth. Snow amounts remain subject to adjustment, but most of northern Minnesota and northwest Wisconsin are expected to see accumulating totals.
According to the agency, the transition from rain to snow on Tuesday will be followed by colder air that supports widespread accumulation. Lake-effect and lake-enhanced snow along the South Shore—including Iron County, Wisconsin—is forecast to linger into Thursday, increasing the likelihood of heavier totals in those areas.
Snowfall probability maps show broad chances for 2 inches or more, with the highest likelihoods across northern Minnesota communities such as International Falls, Ely, Grand Marais, Cook, Hibbing, and Two Harbors. Probabilities for 6 inches or more also increase toward the Arrowhead and into portions of the Wisconsin South Shore, where lake-enhancement may push localized amounts higher.
While exact totals remain uncertain, the National Weather Service highlights northern Minnesota and areas near the South Shore as the most favored regions for heavier snow. Slick roads, reduced visibility, and slow travel are likely Wednesday morning and again Wednesday night as lake-effect bands redevelop.
Forecasters recommend monitoring updates closely through early week as confidence increases and snowfall projections are refined. Travelers heading out ahead of Thanksgiving may encounter challenging conditions, particularly in higher-probability zones near Duluth, the North Shore, and Iron County, Wisconsin.
