Turning hot and humid through midweek | June 27, 2026

TONIGHT

A few showers and thunderstorms may linger through the evening before coverage gradually fades later tonight. Patchy fog may develop after about 2 a.m., and lows settle in the upper 60s with a light east breeze. It will not rain all night everywhere, but the evening still carries enough of a storm threat to keep a weather eye nearby.   

TOMORROW

Patchy fog early gives way to a partly sunny, warmer, and much less active day. Highs climb into the mid 80s, with a light east wind around 5 mph. After the unsettled Saturday, this looks like a far more usable day for outdoor plans, and most of central Indiana should stay dry from start to finish.

TOMORROW NIGHT

Clear early, then becoming partly cloudy toward daybreak, with lows in the low 70s. A light south southeast breeze around 5 mph keeps the air moving just enough, and the humidity stays elevated overnight. Quiet weather continues.  

MONDAY

Mostly sunny and hot with highs pushing into the low 90s. A south southwest breeze around 5 to 10 mph keeps the air moving, but the bigger story is the heat and humidity building in. Heat index values over 100 are possible during the afternoon, so outdoor plans will need extra water and more breaks.

MONDAY NIGHT

Mostly clear and warm, with lows around the mid 70s. A light south southwest breeze continues overnight, and there will be very little cooling after sunset. It stays dry, but the muggy feel hangs on.

TUESDAY

Sunny and even hotter, with highs in the low to mid 90s and a light southwest breeze around 5 mph. This is another day where the heat becomes the main impact, and it will not take long to feel it during the afternoon. Outdoor work and summer activities will need to be paced carefully.

TUESDAY NIGHT

Clear and warm again, with lows in the mid 70s and a light southwest wind. The air remains sticky overnight, and there is still no meaningful rain signal for Indianapolis.

WEDNESDAY

Mostly sunny and hot, with highs in the low to mid 90s. Wind stays light, becoming south southwest around 5 mph in the afternoon. Heat remains the main concern, and another uncomfortable summer afternoon is expected across central Indiana.

7 DAY FORECAST

After today’s storm chances taper away, the pattern flips quickly toward heat and humidity. Sunday looks quieter and warmer, then Monday through at least Wednesday trend hot with highs in the 90s and heat index values over 100 possible at times. Rain chances stay very low through midweek, with only low-end storm chances returning later Thursday into Friday. Overall, the bigger concern after Saturday becomes summer heat rather than repeated storm chances.
