INDIANAPOLIS (WISH) — Dangerous heat will persist for the next several days, with some storm chances possible this weekend.

Today:

Today will be the hottest and most humid day of the week, as a ridge of high pressure strengthens through the late morning hours. Highs are expected to reach the mid-90s, with heat indices potentially exceeding 105°F this afternoon.

The entire state is under a heat advisory due to the extreme heat forecasted for today.

Tonight:

The strong upper-level ridge will begin to flatten and weaken, allowing a boundary to slide in from the northwest tonight into the overnight hours. Scattered showers and thunderstorms are possible, with the best chances this evening and early overnight, particularly for northern counties.

Overnight lows will remain uncomfortable, falling to the mid-70s. Dewpoint temperatures in the low to mid-70s will make for an unpleasant night.

Friday:

As the heat shifts west into the central Plains, storm chances will increase across the Midwest. Scattered showers and thunderstorms are expected on and off through Friday.

No widespread severe weather is anticipated, but gusty winds and torrential downpours are possible.

High temperatures will reach the low 90s, with feels-like temperatures around 100°F.

Weekend:

Saturday will be similar to Friday, with partly cloudy, hot, and humid conditions. The unsettled pattern may bring scattered showers and thunderstorms in the afternoon. Gusty winds and torrential downpours are possible to start the weekend.

7 day forecast:

Hot and humid conditions will continue to close out the weekend, with slightly lower but non-zero rain chances on Sunday. Any storm activity on Sunday would likely occur during peak heating in the afternoon and early evening.

The heat will persist for at least the first few days of next week, with highs in the low 90s and spotty afternoon storm chances Monday through Wednesday. A significant pattern shift is expected late next week, as a trough from Canada should bring much cooler temperatures as we begin August.
