STATEWIDE–Portions of Indiana are under a heat advisory until 9 pm Wednesday with many places in Indiana expected to get heat indices between 100 and 110. Severe storms are also possible.

“The heat advisory area is essentially from Rockville to Greencastle over towards Shelbyville and Greensburg and points south. But the big story is that it’s going to be hot everywhere, so you’ll want to take precautions,” said Jason Puma, meteorologist with the National Weather Service in Indianapolis.

He advises you to drink plenty of water, stay inside if you can, and wear light-colored clothing.

“Light-colored clothing will reflect more light and heat. Darker colors absorb more heat. Think of a blacktop vs the grass. If you were walking on the blacktop in this heat, it would be much hotter than the grass, which is green,” said Puma.

The areas at greatest risk of severe weather Wednesday are along I-70 and points south.

“It does include places like Hamilton County, Lebanon, New Castle, and are other places south of there,” said Puma.

Those areas are under a “slight risk” of severe weather. That means that scattered severe storms are possible but typically are short-lived and not widespread.

“The main threats would be damaging winds, large hail, and lightning. The big window for severe storms would be in the afternoon hours and in the overnight hours,” said Puma.

Puma says a tornado can’t be ruled out. He expects things to start cooling down more by Friday with highs in the low 80s in many places across Indiana.
