Overview
- The Storm Prediction Center, which issued Friday risk levels, said 38 million people from North Texas to Michigan face severe storms with the greatest tornado threat in Iowa, Wisconsin and northern Illinois.
- The National Weather Service flagged flash flood danger from slow-moving storms over northern Michigan, Wisconsin, western Missouri and eastern Kansas as downpours ramp up through the evening.
- Forecasters said temperatures will drop quickly as the front moves east, with some locations falling more than 30 degrees and a chance of late-season snow in the Upper Midwest and Upper Great Lakes.
- Local forecasts show a wet Sunday and a cooler start to next week in New England and parts of the Mid-Atlantic, with periods of rain and a few mountain snow showers possible as colder air arrives.
- Wisconsin communities that saw record flooding on Wednesday began cleanup in what officials on Friday called a risky window for workers, who were urged to watch for debris, high water and new storms.
