Skies will be mostly sunny today and tomorrow, with daytime highs in the mid 80s. Skies will be partly to mostly cloudy on Saturday as the surface front will be over the area, and highs will drop into the mid 70s. High pressure will start to build into the area for Sunday and push the clouds out. Skies will be mostly clear and highs will be in the mid to upper 70s.
So it looks like all you will need is a good supply of sunscreen, a hat, and shades to enjoy the exciting racing that will take place at Mid-Ohio. As of now, I will not have radar up unless a threat of rain develops for the on-track action.
