We'll reach 88 this afternoon with high humidity which will make it FEEL LIKE 102. This is just shy of Heat Advisory criteria. However, you will want to make sure you stay hydrated and wear light-colored and loose-fitting clothing.
There will be the chance for a few storms today, especially north of Indy. The SLIGHT risk was expanded to include the northern half of Indiana. We could see a few severe T-storm warnings into the afternoon.
Today through Saturday our heat index will be between 100 and 105 each afternoon. Our transition day is Sunday with highs in the 80s, however, it will still be HUMID. We'll have spotty T-storms around on Sunday which will keep the temperatures in the 80s BUT we'll finally get rid of the humidity by Monday!
For the Brickyard 400 on Sunday a few spotty T-storms will be possible. It will be hot and humid at the track!
Early next week, it will FEEL so much better! Highs will be in the low 80s by Monday with LOW humidity.
