Indianapolis is starting Tuesday with clear skies and temperatures around 79°F, but the calm setup is expected to give way to a much rougher afternoon. Scattered showers and thunderstorms are forecast to build through the day, with some storms capable of becoming severe. The high should reach about 88°F before temperatures ease slightly late in the day.
The biggest storm window currently looks to be from afternoon into evening, when repeated rounds could bring damaging wind gusts, downpours and sharply reduced visibility. The National Weather Service Indianapolis puts the daytime rain chance at 80%, with gusts up to 20 mph and heavier bursts possible near storms. New rainfall totals are generally expected at a quarter to half inch, but localized amounts could be much higher.
Flood Watch Runs Through Tuesday Night
Central Indiana is under a Flood Watch from noon Tuesday through midnight, as storms may track over the same neighborhoods more than once. Isolated rainfall totals of 2 to 4 inches are possible, raising the risk of flooding along creeks, streams, low-lying roads and other flood-prone spots. Residents should monitor later alerts and avoid driving through flooded roadways.
Storm chances continue Tuesday night, with a 70% chance of showers and thunderstorms and a low near 70°F. Some storms could remain severe, while rainfall totals overnight may reach three-quarters to 1 inch in spots. The overnight temperature may rise slightly, reaching around 72°F before dawn.
Storms Linger Into Wednesday
Wednesday stays warm at around 88°F with scattered showers and thunderstorms, followed by another stormy night and a 70% rain chance. Forecasters expect the main hazards Wednesday to remain heavy rain and damaging winds, especially before a front pushes south late Wednesday into early Thursday. That front should bring some relief from the heat and humidity.
Thursday brings a high near 85°F and a 70% chance of rain, with showers possible before thunderstorms become more likely later in the day. Friday looks cooler, topping out around 82°F, though showers and storms may still linger before the pattern begins to calm. Nighttime lows fall from about 69°F Thursday night to 66°F Friday night.
Weekend Forecast Trends Drier
Saturday is forecast to be mostly sunny with a high near 84°F, though a 30% chance of showers and thunderstorms could still disrupt morning plans. Sunday turns warmer again, reaching about 88°F with only a slight storm chance. Monday should be mostly sunny and cooler near 82°F, with just a small chance of an afternoon shower or thunderstorm.
For anyone heading out Tuesday, the safest bet is to keep outdoor plans flexible and have a way to receive weather warnings. The heaviest rain may be brief in one neighborhood and much more persistent a few miles away, so conditions can change quickly across the metro. The forecast is less about one all-day washout than a series of storm rounds that could pile up rain.
