Clouds are hanging over Indianapolis International Airport this morning with temperatures near 39°F, but skies are expected to clear and the day should turn mostly sunny with a high near 61°F. Monday will run noticeably warmer, climbing toward 70°F, before a wetter pattern muscles in later in the week. A stronger storm system is set to move in Tuesday night into Wednesday, bringing periods of heavy rain and embedded thunderstorms. Areas south of I‑70 that are already seeing rivers and creeks on the rise will want to keep a close eye on the forecast.
Today And Monday: A Quiet, Warm Stretch
Sunday, March 8, 2026, is on track to turn mostly sunny this afternoon with west‑southwest winds around 5 to 10 mph and gusts to about 20 mph. Lows tonight will slide into the mid 40s. Next Monday should push into the upper 60s to near 70°F as a southerly flow strengthens and taps into warmer air. Those timing and temperature details line up with the latest local forecast from the NWS Indianapolis.
Midweek: Heavy Rain And Storms Possible
Another round of rain is expected Tuesday, March 10, 2026, with showers possible in the afternoon and a stronger period of rain and thunderstorms arriving Tuesday night into Wednesday, March 11, 2026. Tuesday’s high is forecast near 75°F with shower chances increasing in the afternoon. The most widespread rain and a good chance of thunderstorms are expected Tuesday night into Wednesday, and winds could turn gusty with this system. Local coverage has already highlighted the potential for locally heavy totals and disruptive downpours during this window, which could complicate travel and outdoor plans.
Flooding Risk And Local Impacts
Forecasters note that rivers and creeks south of I‑70 are running high after recent rains, and additional rainfall late Tuesday into Wednesday, including pockets of heavier downpours, could prolong or worsen minor to moderate flooding in low‑lying and poor‑drainage areas. Models and official guidance suggest an extra inch or two is possible in some spots during the midweek event, with localized higher amounts where thunderstorms train. Given saturated soils, drivers should avoid going through standing water and be ready for localized road closures near creeks and the White River. For official watches and statements, see the NWS Indianapolis.
Plan Ahead
If you have outdoor plans Tuesday night or Wednesday, it may be wise to move them or line up an indoor backup, and to secure loose outdoor items ahead of the changing weather. Drivers should give themselves extra time, stay away from flooded streets, and be ready for gusty winds on Wednesday that could bring down a few limbs. Keep an eye on updates from local authorities and the National Weather Service, since the exact timing and placement of the heaviest rain can still shift over the next 48 hours.
