Rain will be out of the area by sunset, and clouds will be decreasing through the night as drier air builds in from the west. Friday will be a beautiful day, with plenty of sunshine, low humidity, and temperatures reaching the upper 60s.
A second cold front will bring showers and a few thunderstorms again on Friday night. Fortunately, I don't expect this rain to have any impact on the racing, as it will be long gone by the time the Indy Lights cars start their warm up at 9:45 am. Any moisture on the track should dry quickly as winds will be blowing from the northwest at 10 to 20 mph. The main weather story for race day will be the cool temperatures, which will be in the 50s. The breezy northwest winds will make it feel even colder, so be sure to bring a jacket if you're going to the race.
