A significant severe weather outbreak is anticipated across the Upper Midwest on Monday, with forecasters warning of potential for strong Tornadoes and destructive winds. The region includes portions of Minnesota, Iowa, and Wisconsin.
Millions face a heightened threat, particularly within a Level 4 out of 5 moderate risk zone defined by the Storm Prediction Center. This area encompasses cities like Minneapolis and St. Paul in Minnesota.
The primary dangers associated with the expected storms include very large hail, damaging wind gusts, and the possibility of strong Tornadoes, potentially EF-2 or higher.
In Minnesota, the threat could unfold in waves. Storms may begin Monday morning, followed by a break before severe weather redevelops in the late afternoon and evening.
The Tornado potential is highest during the late afternoon and evening round. Forecasters note that if storms form as discrete supercells, strong and intense tornadoes are possible across the area.
Residents in affected areas are urged to prepare. This includes developing a severe weather safety plan and ensuring access to warnings and updates. Safe shelter locations at home, school, or public places should be identified.
The storm system is fueled by a strong jet stream and a strengthening low-pressure system moving through the northern Plains towards the Great Lakes.
The widespread severe weather threat is expected to continue into Tuesday across a different section of the country, extending south from Texas and northeastward.
