Indianapolis rolled into Sunday, May 24, 2026, under a blanket of patchy fog and sticky air, with temperatures hanging in the low 60s near the airport. Clouds will hang tough through the morning before scattered showers start to pop by mid-morning, with scattered thunderstorms building over the metro later this afternoon. Highs should top out near 75°F, and a narrow line of storms is expected to approach the city in roughly the 3 to 5 p.m. window, bringing brief but heavy downpours.
What To Expect Today
Scattered rain showers could start as early as about 9 a.m., with the most widespread activity likely from late morning into early evening. Most spots will pick up around a tenth to a quarter of an inch of rain, though localized heavier bursts may cause quick ponding on urban streets. For the latest timing tweaks and county-level details, check the National Weather Service.
Fog And The Morning Commute
Patchy, locally dense fog will knock down visibility during the predawn and morning drive, so plan a little extra time and ease off the gas, especially on bridges and overpasses. As the day warms, low clouds should lift, but any passing showers will leave behind wet pavement that slows traffic and stretches out braking distances.
Indy 500 And Weekend Plans
With a full slate of race-day events on tap at the Indianapolis Motor Speedway, those afternoon storms could factor into late-race conditions and make post-race traffic a soggy crawl for fans heading home. We broke down the broader wet pattern in our May 20 forecast; see our broader soggy pattern for background on the setup.
Memorial Day Outlook
Surface high pressure should build in for Monday, Memorial Day, bringing partly sunny skies and a warmer feel, with highs near 81°F for most neighborhoods. A stray, isolated shower could sneak into far southern areas, but most outdoor plans look dry for the holiday.
Bottom line: toss a compact umbrella in the car and expect wet roads during the afternoon commute. If your plans land in that 3 to 5 p.m. window, keep an eye on updated forecasts and be ready for brief, heavy downpours.
