Detroit, Michigan – A developing storm system is set to bring severe weather across southern Michigan Thursday evening, with forecasters warning of large hail, strong winds, and possible thunderstorms.
The National Weather Service says the biggest concern isn’t tornadoes—it’s hail that could grow as large as hen’s eggs, posing a significant threat to vehicles, roofs, and outdoor property.
Large hail emerges as primary threat
Meteorologists are highlighting hail as the main hazard with this system, especially across the southern tier of Michigan’s Lower Peninsula.
“Hail looks to be the main severe weather hazard, particularly in southern areas.”
The most intense zone stretches across far south-central and southeast Michigan, where hailstones could reach up to 2 inches in diameter.
In areas farther north, including parts of the Detroit suburbs, hail is still expected but may range between ½ inch to 1½ inches.
Storms expected during early evening hours
Forecasters say the peak timing for severe weather will be early Thursday evening, when atmospheric conditions are most favorable for storm development.
Areas under the greatest risk include:
- Southwest Michigan: St. Joseph, South Haven, Kalamazoo
- Southeast Michigan: Ann Arbor, Jackson, Adrian, Monroe
These regions fall under a “slight risk” category, meaning storms could become strong and produce localized severe impacts.
Strong winds and thunderstorms also possible
In addition to hail, the storm system may bring:
- Wind gusts up to 65 mph
- Frequent lightning and heavy downpours
- A low risk of isolated tornadoes
“Damaging winds and hail will be the primary concerns, with a lower tornado threat.”
Even though tornado chances are limited, officials say residents should remain alert as conditions can change quickly.
Narrow corridor for most intense hail
Unlike widespread storms, the largest hail threat is expected in a more concentrated area, particularly across the southernmost counties.
This means some communities could see significant damage, while others nearby may experience only lighter impacts.
Residents urged to prepare ahead of storms
With the potential for large hail and damaging winds, officials are advising residents to take precautions before storms arrive:
- Move vehicles into garages or covered areas
- Secure outdoor items that could be blown away
- Stay indoors during storm activity
- Monitor weather alerts for updates
“Even isolated storms could produce severe impacts, especially with large hail.”
Stay weather-aware as system develops
As the system moves through Michigan, conditions could evolve quickly, especially during the evening commute.
Residents are encouraged to stay updated with local forecasts and warnings, as severe weather can develop rapidly and vary by location.
