Total liquid with this storm will be 2-3 inches from Thursday night through Sunday morning. Some of that will be freezing rain which will accumulate ice on power lines and tree branches.

Impacts

Flooding will impact the most people in southeast Michigan. Expect everything from closed roads, flooded underpasses, moderate river and stream flooding to flooded basements and even east side lake shore flooding. Fewer people will see impacts from ice, but the effects will be dramatic. Any time we receive more than 0.25" of ice, power outages are usually a given. But with the potential to see 0.50" or more of ice, expect widespread power outages across a large chunk of our region.
