Multiple tornado warnings and severe weather alerts were issued across the Midwest on May 15, 2025, as powerful storms swept through Minnesota, Wisconsin, Michigan, and parts of Illinois, including the Chicago metropolitan area. The tornado warning alerts were issued due to record heat and unstable atmospheric conditions, prompting urgent advisories from weather officials and emergency agencies.
Minnesota and Wisconsin: Twin Cities in the Crosshairs
A widespread tornado warning was issued across 35 counties in Minnesota and 20 counties in Wisconsin. This included major urban areas such as Minneapolis, St. Cloud, Blaine, Brainerd, and Eau Claire. The tornado warning covered a significant portion of the region, with meteorologists warning residents of a heightened tornado risk until late evening.
In the Twin Cities region, people were strongly advised to take shelter immediately after the tornado warning was issued. Emergency officials highlighted the importance of moving to basements or interior rooms without windows. With the tornado warning in effect, local emergency operations centers were activated to coordinate response and monitor developments.
Chicago on Alert Amid Record Heat
As the storm system advanced eastward, a tornado warning was not yet issued for Chicago, but the city was under close watch. The extreme heat and humidity created ideal conditions for a tornado warning to be declared at any moment. Residents were told to stay alert, as the potential for severe weather remained high throughout the evening.
Emergency managers in the Chicago area stressed the importance of staying prepared, noting that even a short-notice tornado warning can save lives. Citizens were reminded to review safety plans and identify their nearest shelters in the event a tornado warning is activated.
Michigan: Tornado Warning for Midland, Bay, and Saginaw Counties
In Michigan, a critical tornado warning was issued just before 12:45 a.m. EDT for Midland, Bay, and northern Saginaw counties. The tornado warning came after radar indicated rotation and possible tornadic activity near Pleasant Valley. Residents in the affected areas were urged to take cover immediately.
This tornado warning was part of a broader severe weather alert that included high winds, large hail, and flash flooding. The Eastern and Thumb regions of Michigan were under a tornado warning and watch throughout the night. Several counties, including Gratiot, Midland, Saginaw, and Bay, reported power outages following the tornado warning.
Safety and Preparedness Measures
Officials across all affected states continued to stress preparedness during this tornado warning outbreak. Key recommendations included:
-
Seek shelter in a basement or a sturdy interior room.
-
Monitor weather apps and broadcasts for tornado warning updates.
-
Avoid mobile homes and vehicles when a tornado warning is active.
-
Prepare an emergency kit with essentials like water, food, medications, and flashlights.
Conclusion
As of early Friday, most immediate tornado warnings had expired, but weather experts advised continued vigilance. The conditions that prompted each tornado warning remain in place, and new tornado warnings may be issued throughout the day.
