Low pressure over the Texas panhandle will move east and spread rain across central Indiana Thursday afternoon. The rain will keep us cool Thursday with highs in the 60s. Embedded thunderstorms are going to be possible on Friday as warmer air mixes in with this system.
The heaviest rain is expected to move out in the pre-dawn hours on Saturday. However, there is still going to be a chance for light rain for the Mini Marathon with temperatures in the mid-50s at the start of the race.
