STATEWIDE--The heat index for cities and towns in Indiana will be over 100 degrees Thursday. Severe storms are also possible throughout Thursday.

“Areas generally near and west of I-65 could see the heat index reach 105-110 degrees after 2 pm,” said Mike Koch, meteorologist with the National Weather Service in Indianapolis. “It looks like we’ll get enough sun and heat to get these storms popping this afternoon.”

Koch believes storms are likely to affect much of Indiana after 4 pm.

“They look like they’re going to develop near or slightly north of the I-70 corridor. With time, they’ll settle to the south and end this evening,” said Koch. “The main threat looks like it’s going to be damaging winds, but we can’t rule out hail or maybe even an isolated tornado. That small tornado threat is for areas east of Indianapolis.”

After the storms move out tonight, temperatures are expected to cool down.

“It’s going to be really refreshing for anyone who’s getting tired of the heat. On Friday, some places in Indiana will have highs only in the 70s,” said Koch. “It’s not until next Thursday that we’re looking at highs in the mid-80s again.”

With the heat on Thursday, however, Koch advises you to drink plenty of water, stay inside when you can, and wear light-colored clothing when you’re outside.
