Indianapolis is waking up Monday under mostly cloudy skies, muggy air and temperatures in the mid-70s, but the day is headed toward a high near 91 degrees. Scattered showers and thunderstorms are possible, and the heat index could reach 101 as southwest winds push warmer air across the city.
The National Weather Service Indianapolis expects southwest winds of 7 to 12 mph, with gusts up to about 21 mph. Storm chances are limited during parts of the late morning and afternoon, but isolated cells could still bring lightning, brief heavy rain and stronger wind gusts before another round develops Monday night.
Storm Risk Builds Tuesday Into Wednesday
Tuesday looks wetter, with a high near 89 and a 70% chance of showers and thunderstorms. Storms could linger from the morning into the afternoon, while Tuesday night brings another 70% chance of rain and possible totals between three-quarters of an inch and 1 inch.
The forecast discussion says organized severe storms are most likely from Tuesday afternoon into Tuesday night and again late Wednesday. Damaging winds, heavy rainfall and localized flash flooding are the primary concerns, with the greatest storm focus generally expected along the I-74 corridor and across northeastern parts of central Indiana.
Hot Monday Gives Way To A Wetter, Cooler Finish
Wednesday should reach about 87 degrees with a 60% chance of showers and thunderstorms, followed by a high near 84 Thursday and 81 Friday. Rain chances remain elevated through Friday morning as a front moves through the region, keeping skies frequently cloudy and outdoor plans vulnerable to sudden downpours.
The weekend looks somewhat calmer, with highs near 83 Saturday and 84 Sunday and storm chances easing to roughly 20% to 30%. No watches or warnings are listed in the current forecast, but residents should keep a way to receive weather alerts, move indoors when thunder is heard and avoid driving through water-covered roads.
