The 110th Running of the Indianapolis 500 is Sunday, and drivers and fans are keeping a close eye on the sky ahead of the green flag.
The race will air on FOX and stream on FOX One with the green flag scheduled for 12:45 p.m. ET. Weather conditions could play a major role, with shifting track temperatures and the chance of precipitation directly affecting tire grip and overall car handling throughout the event.
Teams will need to stay sharp and highly adaptable on the pit box, as sudden changes in cloud cover can quickly alter a car’s balance. Spotters and strategists will be glued to radar screens to make sure they are not caught off guard by any fast-moving systems.
According to FOX Weather, last year’s forecast showed a 15% chance of rain on race day at the start of the event. Temperatures climbed into the low 70s with a mix of clouds and sunshine throughout the day, and similar conditions are expected for this year’s race.
Historical averages only provide a baseline, and Midwestern spring weather is notoriously unpredictable. A slightly warmer day could quickly raise track temperatures, forcing engineers to increase downforce to compensate for a slicker racing surface.
