Looking at the latest high-resolution models and radar trends this morning, I do believe that we stay mainly dry through the morning hours at Road America, but those thunderstorm chances really begin to ramp up around 12:00 pm. I wouldn't be surprised if there is a passing light shower during the morning hours, but chances will be rather small. If there is a delay today due to storms, it may only be for a couple of hours as we may have a mainly dry slot around 3:00 PM-4:00 PM. A passing shower or two is possible but they should be light in nature. Afternoon high tops out around 70 degrees. Winds will be out of the southeast at 8-16 MPH. Rain chances during morning: 20%-30%. Rain Chances from 12:00 PM-3:00 PM: 80%. Rain chances after 4:00 PM: 30%-40%.
