(CNN)The Midwest including most of Wisconsin will be at risk from possible tornadoes, strong storms and hurricane-force winds Wednesday as the region is under a level 4 out of 5 threat of severe weather.
"A favorable pattern will exist over Minnesota/Wisconsin toward Lake Michigan today, supporting intense severe thunderstorms and possible derecho development later this afternoon/evening," said the Storm Prediction Center.
To be called a derecho, severe storms must have winds in excess of 58 mph and cause damage spanning at least 250 miles. The resulting conditions can be described as a tropical storm over land. National Oceanic and Atmospheric Administration climatologist Adam Smith described a 2020 derecho to CNN Weather as an inland-hurricane, with winds reports in excess of 100 mph and hurricane-force winds lasting for up to 45 minutes.
A moderate risk for severe weather has been issued for the Midwest by the Storm Prediction Center Wednesday
The severe threat will start in eastern Minnesota in the afternoon, pushing through Wisconsin in the evening hours.
