Indianapolis woke up under gray skies and thick, muggy air Wednesday, with temperatures near 63°F at Indianapolis International Airport and light showers already creeping across the metro. A Flood Watch is posted for parts of south-central Indiana through 2 p.m. Wednesday, May 20, 2026, and the steadiest rain is expected to hang around through the mid-afternoon commute.
Morning Commute And Flood Watch
According to the National Weather Service in Indianapolis, a Flood Watch remains in effect through 2 p.m. Wednesday for south-central counties, where soils are already saturated and pockets of urban flooding are possible. Off-and-on showers will feature occasional downpours, with most spots still likely to see less than a quarter inch of rain today, though localized heavier bursts could leave water pooled at low-lying intersections. Drivers are urged to allow extra time, slow down, and skip any shortcut that involves plowing into a flooded lane.
Afternoon And Late-Week Outlook
Wednesday stays on the cool side, with a high near 66°F and north to northeast winds around 8 to 10 mph before conditions dry out briefly tonight. That lull does not last long. A wetter pattern returns late in the week, with forecasters calling for widespread showers and thunderstorms on Friday, May 22, 2026. Many neighborhoods could pick up a quarter to a half inch of rain, with heavier pockets in stronger storms. Temperatures then rebound into the upper 70s and low 80s for the holiday weekend, but scattered storms linger in the forecast and could interrupt outdoor plans through Memorial Day, Monday, May 25, 2026.
Flights, Transit And Safety Tips
Low clouds and occasional reduced visibility could spell delays for flights at Indianapolis International (IND) and nearby regional fields, with the smallest airports most likely to struggle with the lowest ceilings. On the roads, commuters should slow for standing water, give themselves extra travel time, and remember that turning around at a flooded roadway is not just a slogan but a solid life choice. If you are planning outdoor events, it is wise to lock in an indoor backup plan for Friday and the holiday weekend.
