Carb Day looks to be a fantastic and warm day at IMS as skies will start off mostly cloudy, but those clouds will be on the decrease throughout the day. Winds will be out of the west to start but will shift out of the south at 5-10 MPH by the afternoon hours. The afternoon high should top out around 84 degrees. There may be a shower that passes over the track well before the activity starts for the day, but the chances of that happening is really small at this point.
On Saturday, the morning hours should be just fine for the autograph session and the public drivers meeting for Firestone Legends Day. Temperatures will start off in the mid-70s for the beginning of the activities and quickly warm up to the lower 80s by the end of the drivers meeting. It will be breezy at times with winds averaging 10-15 MPH out of the southwest with gusts up to 25 MPH possible at times. After that, clouds increase during the afternoon hours and there will be a small chance of a scattered afternoon to early evening shower or thunderstorm. The afternoon high will top out around 86 degrees. Chance of rain is only 30%.
Sunday will be a day that will feature mostly cloudy skies throughout the day with a very small chance of a shower during the morning hours and into the early afternoon hours, but with the heating of the day, those rain chances will ramp up to around 50% after 2:00 pm. Thunderstorms should be scattered in nature, but there could be just enough organization that there may be a ragged line of storms that move through. It is still just too far out for the higher resolution models to give us a solution. Winds will be out of the southwest and will shift out of the west averaging 5-10 MPH but gusts up to 20 MPH are possible at times. The afternoon high should top out around 80 degrees.
