Indianapolis rolled into Saturday, June 20, under a blanket of partial cloud cover, with morning temperatures in the mid‑60s and an afternoon high near 80°F on tap. A few isolated showers could sneak through by midday, but the main show is set for Sunday, when a stronger system moves in with widespread rain and the threat of heavier downpours. Light west‑to‑northwest breezes this afternoon are expected to swing around from the southeast ahead of that Sunday system.
What To Expect
A Flood Watch is in effect from Sunday afternoon, June 21, through Monday morning, June 22, for much of central Indiana as a slow‑moving low pressure system spins in rounds of showers and thunderstorms. The National Weather Service is calling for 1–3 inches of rain, with higher local amounts where storms repeatedly track over the same spots, which could trigger flash and urban flooding.
Plan on a soggy Sunday. Showers are likely on and off for much of the day, with heavier, steadier rain possible Sunday night, especially across south and central Marion County and neighboring counties, according to forecasters. If your weekend plans depend on dry skies, you might want to have a backup ready.
