Indianapolis started today on a deceptively calm note, with clear skies, a crisp 56°F and high pressure in control. The city can count on sunshine and a high near 80°F through the day, but the quiet stretch will not last long. Showers and thunderstorms are expected to creep back in tonight and ramp up into a more organized, soaking event by late Thursday into Friday.
Tonight and Thursday
Through this afternoon, skies stay mostly sunny as mid- and high-level clouds gradually increase. Late tonight (Wednesday night, June 24) there is a slight chance for a few isolated showers, with lows in the mid-60s and light south-southwest winds keeping things mild.
Thursday turns warmer and a bit more unsettled. Expect partly sunny skies, a high near 83°F and scattered storms possible in the afternoon as the atmosphere starts gearing up for the main event.
Late Thursday Night Into Friday: Flood Risk
The primary concern arrives late Thursday night (June 25) into Friday (June 26), when a surface low will pull Gulf moisture north and wring out efficient downpours over central Indiana. According to the National Weather Service, many locations could see 1–3 inches of rain, with localized flash flooding the main hazard.
Slow, soggy commutes are on the table, along with ponding on low-lying streets and temporary road closures where storms repeatedly track over the same neighborhoods. If your usual route floods quickly, have a backup plan ready.
Weekend and Next Week
The front is likely to hang around into Saturday, keeping scattered showers and thunderstorms in play, then lift north on Sunday. That shift will open the door for hotter, more humid air to surge in early next week. Highs are forecast to climb into the low 90s Monday and Tuesday (June 29–30), with afternoon heat indices pushing into the low 100s.
Outdoor plans early next week will feel more like midsummer survival training. Plan for heat, strong afternoon sun and limited relief unless you can find shade or air conditioning.
Local Context
Recent heavy weekend rain already put some stress on the city’s low spots. We flagged that round in an earlier Hoodline piece; see our soaking Sunday downpours coverage for how low-lying streets handled it. City crews and utilities will likely be busy again if several more inches fall, so it is worth checking local alerts and road conditions before heading out.
What You Can Do
If you live in a flood-prone area, move valuables out of basements ahead of the heaviest rain. Avoid driving through standing water, since depth and current can be deceiving, and give yourself extra time for late Thursday night through Friday commutes.
Keep your phone charged, follow local emergency messages and check updated forecasts, especially if your plans depend on dry weather. This is a good stretch to keep the umbrella by the door and the weather app close at hand.
