High Heat, Humidity, And Severe Storm Risk Wednesday

Another hot day in Central Indiana with highs near 90 and plenty of haze in the sky. Quiet for most of the night but spotty downpours are possible west of Indy early Wednesday morning... mainly between 3 AM - 8 AM.

These likely weaken before reaching the Indy metro area and most of Wednesday will be hot and very humid... as the Muggy Meter gets in the oppressive range.

Highs near 90, combined with dewpoints in the 70s, leads to heat indices peaking-out near/above 100 between 2 PM - 7 PM Wednesday afternoon.

We'll definitely be on radar watch with locally heavy storms possible in the high heat and humidity. The coverage of storms should be maxed-out Wednesday night along a cool front moving across the state.

Central and northwestern Indiana are under Level 1 and 2 risks of severe storms respectively... mainly for locally severe wind. But the overnight timing of the front is thankfully not ideal for widespread severe weather.

This front brings slightly cooler air Thursday/Friday with highs in the mid-80s and tolerable humidity.

Temperatures quickly return to 90+ this weekend and heat indices 100+ into early next week.

We're expecting a disturbance near the Gulf of Mexico to become "Barry" over the next 48 hours. There's varying potential solutions on how strong this system could become... even some solutions brining remnant moisture into Central Indiana later next week. But there's little confidence on any given set up at this point. We'll monitor and update going forward - Sean Ash
