A potent weather system is set to bring a high risk of severe storms to Southeast Michigan on Tuesday, with the main threat arriving after dark and lasting into the early morning hours of Wednesday. Forecasters are warning residents to prepare for the possibility of damaging straight-line winds, hail, and even isolated tornadoes as a strong line of thunderstorms sweeps across the region.

Why it matters

Severe overnight storms can be especially dangerous, as many residents may be asleep and unaware of the threat. Power outages, downed trees, and flash flooding are all possible impacts that could disrupt daily life in the affected areas.

The details

The severe weather threat is being driven by a warm, humid air mass moving into the Great Lakes region, which will destabilize the atmosphere and set the stage for powerful thunderstorm development. While the initial storms are expected to form further west, they will merge and take aim at Southeast Michigan as the sun goes down on Tuesday. The main dangers will be damaging straight-line winds capable of snapping trees and power lines, as well as the potential for isolated tornadoes and hail. Heavy rainfall could also lead to localized flooding in low-lying or urban areas.

• The warm front will push north across the region during the mid-to-late afternoon on Tuesday.
• The most significant and widespread severe weather threat is expected between 8 p.m. and 2 a.m. Tuesday night into Wednesday morning.

What’s next

Residents in Southeast Michigan should closely monitor the weather forecasts and be prepared to take shelter if severe thunderstorm or tornado warnings are issued for their area on Tuesday night. It's important to have a plan in place and to stay alert, especially during the overnight hours.
