Indianapolis, IN
Unsettled Friday and Saturday, then summer heat returns early next week | July 10, 2026
TODAY
Partly sunny and warm with scattered showers and thunderstorms likely through much of the bookends of the day. Highs reach the mid 80s, with a west southwest breeze around 5 mph. It does not look like nonstop rain from start to finish, but this is the least reliable daytime period in the forecast, and any stronger storm could drop a quick heavy downpour with a gusty burst of wind.
TONIGHT
Scattered showers and thunderstorms remain possible through the evening, then another lower-end storm chance lingers late overnight. Lows settle near the upper 60s, with light wind. The severe risk looks lower than it is Thursday night, but a few pockets of heavier rain are still possible if a boundary stalls close enough to central Indiana.
TOMORROW
Mostly cloudy and not quite as hot, with another chance for showers and thunderstorms developing mainly after mid afternoon. Highs reach the low to mid 80s, with a light northeast breeze around 5 mph. Much of the first half of the day should be usable, but later afternoon and evening plans will still need a weather eye.
TOMORROW NIGHT
A few showers and thunderstorms may linger early, then the trend turns quieter with mostly cloudy skies overnight. Lows fall to the upper 60s, with an east northeast breeze around 5 mph. It is a calmer setup than Friday night overall, even if an early interruption is still possible.
SUNDAY
Mostly sunny and warmer with highs in the mid 80s. An east breeze around 5 to 10 mph keeps the day from feeling too stagnant, and this looks like one of the cleaner forecast days of the stretch. Most of central Indiana should stay dry from start to finish.
SUNDAY NIGHT
Mostly clear and seasonably mild, with lows around the mid 60s and a light east northeast breeze. Quiet weather continues overnight with no meaningful travel concerns.
MONDAY
Sunny and hotter, with highs climbing into the upper 80s. A light east wind around 5 mph holds through the day. After the unsettled end of the workweek, this looks like a very usable summer day with heat becoming the main story instead of storms.
MONDAY NIGHT
Mostly clear and warm, with lows near 70 and only a light breeze. There will be little trouble overnight, and the warmer pattern settles in more firmly.
TUESDAY
Sunny and hot again, with highs near 90. Wind stays light, becoming east southeast around 5 mph in the afternoon. This is another day where the weather looks broadly quiet, with heat the main thing to plan around.
7 DAY FORECAST
The main concern in the near term is the unsettled Friday into Saturday period, when repeated rounds of showers and thunderstorms could bring quick heavy rain, especially Friday afternoon and evening. After that, the pattern trends warmer and drier from Sunday into at least Tuesday, with highs returning to the upper 80s and lower 90s while heat index values stay more manageable than the late-June heat. By Wednesday and Thursday, isolated afternoon and evening storms begin to creep back into the forecast, with a more noticeable thunderstorm threat showing up later next week into next weekend.
