Saturday should be an overall nice day with warm temperatures, as highs are expected to reach the low to mid 80s. Skies will be mostly sunny with a slight chance of a shower or thunderstorm. Chance of rain is 20%. Winds will be out of the SW at 5-10 MPH.
Sunday will once again feature warm temperatures with partly cloudy skies. A chance for showers and thunderstorms are in the forecast. As of timing and placement of these, its too early in the game to exactly say when and where they will develop. Highs are expected to reach the mid 80s. Winds will be out of the west-southwest at 5-15 MPH. Chance of rain is 40%.
Hopefully within the next couple of days, I should be able to get a better idea on the rain chances for Sunday. Radar will be up and running for the Milwaukee Mile before the event weekend.
