Indy 500 fans and drivers to endure scorching heat Sunday

The Indianapolis 500 could set a new track record for heat during this year’s race.

If the current forecast holds, it could reach 94 degrees or higher during the race with a 100 degree heat index, which factors in humidity. That would shatter the previous race day record of 92 degrees set in 1937, and could also break a 101 year record for the day.
