Indianapolis is trading its recent breather for a hot, humid Tuesday, with sunshine pushing the thermometer to about 93 degrees and heat-index values near 100. Skies were clear early Tuesday morning, but the quiet start will not last all day: a chance of showers and thunderstorms develops Tuesday evening. The bigger story is a sticky stretch that keeps storm chances around through the workweek before a cooler turn arrives Sunday and Monday.
Tuesday Brings Sunshine First, Storms Later
South winds around 9 mph will accompany the afternoon heat. Tuesday carries a 30% chance of showers and thunderstorms after 2 p.m., with locally heavy rain possible, according to the National Weather Service Indianapolis. Forecasters also say an isolated storm could produce damaging winds, while locally heavy rain remains a concern.
Wednesday Keeps The Heat On
Wednesday will bring another high near 91 degrees, with warm conditions continuing. Storm chances continue from the morning into the afternoon and evening, with a 50% precipitation chance. Overnight temperatures will stay unusually mild, hovering near 72 degrees.
Storm Chances Linger Before A Weekend Cooldown
Thursday brings likely rain showers and thunderstorms with a high near 88 degrees, followed by Friday temperatures within the broader Thursday-through-Saturday range and Saturday with storm chances. The forecast keeps at least a slight chance of storms around Thursday and Friday, while storm chances continue Saturday night. Sunday turns cooler near 88 degrees and mostly sunny, and Monday finally looks more fall-like, with a high in the 70s and a low in the 50s.
Plan For Heat And Sudden Downpours
Outdoor plans Tuesday and Wednesday should include shade, water and regular breaks, particularly during the hottest afternoon hours. Evening events may also need a backup plan as storms could develop quickly and bring brief heavy rain. The latest outlook represents a substantive update to an earlier Hoodline forecast, with the heat and storm timeline now more clearly defined.
