Marquette, Mich. – Severe thunderstorms are set to erupt along the Michigan-Wisconsin border Monday afternoon, bringing the highest threat of tornadoes, large hail, and damaging winds to western Upper Michigan communities. Residents from Iron Mountain to Marquette should be prepared for rapid changes in conditions as storms intensify through the evening and overnight.
According to the National Weather Service in Marquette, an enhanced risk (level 3 of 5) for severe storms covers western Upper Michigan, with a 30–44% chance of damaging weather within 25 miles of any location. The first round of storms is expected after lunchtime Monday, mainly affecting border areas like Menominee and Ironwood. A second, potentially more dangerous round could strike after sunset, increasing the tornado risk especially near the Wisconsin line.
Primary hazards include strong winds capable of downing trees and powerlines, large hail, frequent lightning, and heavy rainfall. The tornado threat has risen for border counties, and brief spin-ups cannot be ruled out. Travel along US-2 and M-28 could be impacted, and power outages are possible.
Residents should have multiple ways to receive weather warnings, charge devices, and avoid unnecessary travel after 4 p.m. Monday. Severe weather alerts remain in effect through early Tuesday, with additional updates likely as the situation evolves.
