UPPER MIDWEST — A busy and active severe weather week is now underway across the Upper Midwest as severe weather begins today in Minnesota and Wisconsin, with Michigan facing two distinct threat zones on Monday April 13, 2026, including late evening storm threats with hail and wind possible across northern Michigan and a low all-hazard severe threat from possible semi-discrete supercells forming across southern Michigan and Indiana.
Severe Weather Kicks Off Today Across Minnesota and Wisconsin
The active weather week for the Upper Midwest begins Monday with severe weather already developing across Minnesota and Wisconsin. The better and more significant severe weather chances are currently focused to the west, where conditions are most favorable for organized storm development today.
The setup across Minnesota and Wisconsin represents the opening chapter of what forecasters are describing as a busy week ahead for the entire Upper Midwest region. Residents in those states should remain weather aware throughout the day as the severe weather threat develops and evolves across the western portion of the region.
Northern Michigan Facing Late Evening Storm Threat With Hail and Wind Possible
The first of two distinct threat zones being monitored in Michigan covers the northern portion of the state. Forecasters are watching for late evening storm development across northern Michigan, with hail and wind identified as the primary hazards associated with this zone.
The timing of the northern Michigan threat during the late evening hours is an important factor for residents to account for when planning activities and monitoring weather conditions throughout the day. Storms developing after dark require extra vigilance as visibility and warning lead times can be more challenging during nighttime severe weather events.
Southern Michigan and Indiana Watching for Possible Semi-Discrete Supercells
The second and potentially more concerning threat zone covers southern Michigan and Indiana, where forecasters say semi-discrete supercells could form and pose a low all-hazard severe threat to the area. Semi-discrete supercells are capable of producing a range of severe weather hazards including large hail, damaging winds, and tornadoes.
The use of the term all-hazard severe threat indicates that forecasters are not ruling out any particular type of severe weather outcome from the strongest cells that may develop across this zone. While the overall risk level is currently characterized as low, residents across southern Michigan and Indiana should remain alert and have a plan in place ahead of the developing storm threat.
