Strong Tornadoes, Damaging Winds Possible In The Upper Midwest Wednesday

Dangerous severe thunderstorms are possible Wednesday afternoon across portions of the Upper Midwest, with the bulk of the severe risk focused on Wisconsin. Storms in and around the risk areas could produce strong, long-lived tornadoes, damaging wind gusts in excess of 75 mph, and hail the size of golf balls or larger.

Wednesday's severe weather risk is a typical side effect of a heat wave like the one parked over the eastern half of the country right now. Severe storms thrive around the edges of the ridge, which often puts the Upper Midwest right in line for multiple rounds of rough storms for the duration of the heat wave.

A low-pressure system will develop over the northern Great Lakes during the day, setting the stage for severe thunderstorms to develop across the Upper Midwest.

The Storm Prediction Center issued a moderate risk, a 4 out of 5 on the agency's scale measuring the threat for severe weather, focused on much of Wisconsin, with an enhanced risk (3 out of 5) radiating outward to include northeastern Iowa and portions of Michigan's Upper Peninsula.

All modes of severe weather are possible on Wednesday afternoon. Strong, long-lived tornadoes are possible across most of Wisconsin. Storms could also produce damaging wind gusts of 75 mph or stronger, as well as hail the size of golf balls or larger.

This is one of those days where it pays to be proactive about watches and warnings. Check your phone and make sure emergency alerts are activated for tornado warnings. Scout out your home, office, or anywhere you plan to be today for safe places to take cover if you go under a tornado warning.

The threat for severe weather will shift toward the Northeast on Thursday, with a threat for tornadoes, damaging winds, and large hail focused on Pennsylvania and western New York.
