This is day two in a row of highs in the 90s for central Indiana, but the difference-maker is a much higher muggy meter, with dewpoints well in the 70s. That's highly uncomfortable and combined with temperatures in the 90s makes it "feel" like 100 degrees-plus for most during midday/afternoon.
Why that's important to you, especially if you're outside for extended periods of time, is that it makes it more difficult for your body to cool itself and requires you to focus on hydration and limiting outdoor time if possible. Dehydration, heat cramps and fatigue are likely in these conditions with properly drinking enough water and taking breaks. Heat exhaustion is possible, especially for younger and/or older groups or those with preexisting conditions.
You'll need to plan on another six days of similar - if not hotter/more humid - conditions going into this weekend. Long-range signals suggest there may be a couple of less humid days early next week, but that break appears to be brief with another hot dome building into July.
Each day also brings a chance of isolated but heavy thunderstorms developing, mainly during the peak-heating hours between midday and sunset. At times, some storms could be severe with 60-plus mph wind gusts.
But rainfall is expected to be highly localized the remainder of the next 7-10 days and conditions are likely for a flash drought to emerge over Indiana, Ohio and parts of Kentucky.
