We’ve finally seen a break from showers and thunderstorms in central Indiana for Sunday’s forecast. It was a nice change compared to Saturday’s stormy evening. But without storms around, there’s nothing to cool us down! Feels-like temperatures were in the mid to low 90s throughout Sunday afternoon. The rest of the evening will be partly cloudy and dry. An isolated shower is possible but it will not be a large threat or a widespread event.

With high pressure finally taking hold of our forecast, the overnight hours will be dry and mostly clear. But with the abundance of moisture in the atmosphere and lack of cloud cover, it’s a quick recipe for patchy fog going into Monday morning. Temperatures will only fall to 72°F overnight.

Get ready for plenty of sunshine on Monday, not to mention some incredible heat and humidity. Temperatures will climb into the upper 80s on Monday and dew points will also remain in the 70s. This is a recipe for an oppressively humid day with feels-like temperatures in the mid to upper 90s. We could even see some feels-like temperatures approaching 100°F on Monday afternoon.

High pressure will lose out to an approaching cold front starting Tuesday evening. While much of Tuesday forecast will be hot, humid and dry in central Indiana, isolated showers and storms cannot be ruled out later in the day as the ridge of high pressure weakens across our state. Temperatures on Tuesday should reach the low 90s with feels-like temperatures in the upper 90s again. But the cold front coming in from the northwest will definitely increase clouds on Wednesday and bring in storm chances. Scattered showers and thunderstorms are expected as this boundary moves ever so slowly through the state. These storms chances should help to drop temperatures a few degrees and we’ll settle into the mid 80s for the rest of the work week. While dew points won’t be as high after the rain arrives, it’s still going to be muggy outside.
