Vassar, MI, to Steubenville, OH, Weather: 7/21/21

I made a trip to Michigan, and will begin my trip down to Virginia today. I caught the edge of the storms yesterday, but was not on the severe warned cell. I did pass through some heavy rain in Flint, MI.

This morning, the weather in Vassar, MI, is hazy, mild and still.
