Today at Road America, temperatures will be rather hot, with an afternoon high expected to reach near 90 degrees. It will fell humid as well, which will put the heat index around 95.
My confidence is increasing that rain will occur on Sunday, but the impacts on the racing will depend on the timing, which is less certain. I expect two main rounds of showers - one will move through this evening, between 8 pm and midnight, then another round on Sunday morning. This will likely impact the Porsche Carrera Cup and the WeatherTech Championship warm-up sessions. If the showers persist long enough, it could affect the start of the WeatherTech race, which begins at 10:40 AM local time. This round of rain is expected to produce about a quarter of an inch of rain, and it may come down heavy enough to cause some delays or stoppages.
Additional showers will continue to be a threat through the rest of the day. But these showers may be more on/off and scattered in coverage, so I expect the potential impacts during the second half of the WeatherTech Championship race and the Lamborghini Super Trofeo race will be lower than in the morning.
