Indianapolis is waking to a muggy 73 degrees Saturday morning, but the bigger concern is water: showers and thunderstorms are expected to move through the city and central Indiana, with a flood watch in effect through Sunday morning. The forecast calls for a high near 83, and forecasters warn that repeated downpours could quickly overwhelm already saturated ground.
Storms Build Through Saturday
Storm chances rise through late morning, with showers and thunderstorms likely into the afternoon as temperatures climb through the upper 70s and low 80s. According to National Weather Service Indianapolis, heavy rain and gusty winds will be the main concerns, although an isolated tornado cannot be ruled out.
Flood Watch Covers Central Indiana
The National Weather Service flood watch remains in effect through 8 a.m. Sunday for much of central Indiana. Excessive runoff could flood rivers, creeks, streams and low-lying or flood-prone locations, with additional rainfall expected Saturday morning through Saturday night. Residents should monitor warnings and never drive through a flooded roadway.
Sunday Stays Hot And Stormy
Sunday brings a high near 87, with a chance of showers and thunderstorms before 5 p.m. and storms likely later in the day. West winds of 3 to 10 mph could gust up to 20 mph, while heat index values above 100 are possible farther south in central Indiana, where a heat advisory is in effect through Sunday evening.
Brief Break Arrives Monday
Monday should turn mostly sunny after a slight early shower chance, with a high around 83 and an overnight low near 63. Tuesday looks like the week's cleanest outdoor window, with sunny skies and a high near 83, before storm chances return Wednesday with a high around 85.
By Thursday and Friday, highs ease to roughly 79 and 78 under partly to mostly sunny skies, with cooler overnight lows in the low 60s. For Saturday plans, keep weather alerts on and have a backup for outdoor events because the main risk is not just rain, but rapidly rising water in vulnerable spots.
