Duluth, Minnesota – Residents across northern Minnesota should prepare for multiple rounds of thunderstorms beginning Sunday night, with the potential for damaging wind gusts and large hail continuing into Monday. Storms could persist overnight before another round develops along a cold front Monday, creating periods of hazardous travel and rapidly changing weather conditions.
According to the National Weather Service in Duluth, thunderstorms are expected to develop in North Dakota Sunday before moving east into northern Minnesota during the evening and overnight hours. Some of those storms may remain strong to severe as they track across the Northland, with damaging straight-line winds and large hail identified as the primary threats.
Communities including Duluth, International Falls, Hibbing, Grand Rapids, Ely, Two Harbors, Virginia, and the Iron Range could experience strong thunderstorms Sunday night. Heavy rainfall may briefly reduce visibility and create ponding on roadways, while isolated power outages are possible where stronger wind gusts occur.
A second round of thunderstorms is forecast Monday as a cold front sweeps east across the region. The greatest potential for numerous severe storms appears to be across portions of central and eastern Minnesota, though isolated severe storms remain possible farther north into the Duluth area. The exact placement of the strongest storms remains uncertain and could shift as new forecast data becomes available.
Residents should secure loose outdoor furniture, charge mobile devices before storms arrive, and have multiple ways to receive weather warnings overnight when severe weather can be more difficult to recognize. Boaters on Lake Superior should also closely monitor conditions, as thunderstorms may produce sudden strong wind gusts and dangerous lightning.
The severe weather threat continues through Monday, and additional watches or warnings may be issued as confidence increases in where the strongest storms will develop. Stay alert for forecast updates, especially if you have travel or outdoor plans across northern Minnesota.
