Thursday will be a bright and sunny day with very comfortable temperatures and lower humidity levels. We'll start off near 60 degrees when the gates open at 7:00 am and warm into the upper 70s for the afternoon high. Winds will be out of the southeast for the most part at 5-10 MPH.
Nearly the same story for Friday as high pressure builds in bringing even more quiet weather with slightly warmer temperatures to the track. Plenty of sunshine once again with highs reaching the lower 80s. Winds will be out of the southeast at 5-10 MPH.
The latest GFS model run is showing a little tongue of moisture that will be moving southward through Wisconsin on Saturday that may be just enough to fire off a passing shower or two during the main heating of the day, but odds of that happening is really small, lower than 20% at this point. Skies will be mostly sunny with just a couple of clouds with highs reaching the lower 80s once again. Winds will start off out of the west at 5-10 MPH but will shift out of the south by the start of the afternoon.
Sunday will be another brilliant day at Road America as skies will be mainly sunny with warm temperatures. No rain is expected at this time and highs will reach the lower 80s. Winds will start off out of the west at 5-10 MPH but will shift out of the south by late afternoon.
Remember, the weather is always changing, so modifications to the forecast can and will be made on the latest data. Radar will be up and running by Thursday morning. Have a great night.
