There are a few small changes to the forecast for Road America today, but the previous forecast thinking appears on track with slight adjustments to timing of rain chances. My confidence in this forecast in increasing as the models are in better agreement with each other today.
There will be a low pressure system tracking across southern Wisconsin and northern Illinois Wednesday night and Thursday. This is faster than the previous forecast. It appears that the majority of the rain with this system will come before sunrise Thursday morning, but there will still be a chance of light rain through the morning. Any rain is likely to end by noon, although clouds will linger through the day.
Friday and Saturday look absolutely perfect for racing. High pressure will be over the northern Plains, which will provide a dry northerly flow. Temperatures will be pleasant, in the lower to mid 70s both days, with mostly sunny skies.
The high pressure ridge over the Plains moves south and an upper level low pressure trough drops south out of Canada on Sunday. There is not a lot of moisture for this system to work with, and some models hold off rain until Monday. But I will continue to mention just a slight chance of rain Sunday afternoon as I can't rule out the possibility of a light passing shower at this time.
