Sunday morning in Indianapolis is starting cool and partly cloudy, about 55°F at Indianapolis International, and should brighten to mostly sunny by late morning. The high will top out near 68°F with a light north breeze, so it is a solid day for errands, a ballgame, or an afternoon walk. Evenings will be noticeably cooler, falling into the mid-40s, so a jacket is still a smart move for any late-night plans. A warmer push arrives Tuesday, bringing a better shot at showers and a few thunderstorms late that night.
Morning Through Sunday Afternoon
The National Weather Service notes only a slight chance of brief pre-dawn showers, but skies should clear quickly and remain mostly sunny through the afternoon. Expect north winds around 3 to 7 mph and low humidity, with temperatures slipping a few degrees after a midday peak near 68°F. Overall, conditions should be dry and calm for the commute and any outdoor events on the calendar. For the official forecast, see NWS Indianapolis.
Earlier Coverage
We flagged the late-week storm potential earlier in the week, and a May 6 update tracked the same warming trend and timing for Tuesday into Wednesday. That coverage noted growing southerly flow and higher dew points that will help fuel showers and isolated storms late Tuesday. For background, see our earlier warm-up alert.
Tuesday Night And Beyond
Temperatures climb into the mid-70s on Tuesday with south-southeast winds that could gust up to around 22 mph, and the National Weather Service says showers and a few thunderstorms are most likely after 8 p.m. Tuesday. Overnight lows around 57°F and southwest winds near 12 mph will line up with the wettest window. Any storms should be mainly organized north of Indianapolis and are expected to bring brief heavy rain and gusty winds rather than widespread severe weather. Wednesday looks drier by late morning with highs near 70, though it will stay breezy, and the weekend trends warmer. Saturday could top out in the mid-80s with scattered afternoon storms possible. These timing and intensity details come from the latest NWS Indianapolis.
