Indianapolis started Sunday on the chilly side, with clear skies, temperatures hovering around 38°F, and pockets of frost settling into low-lying spots. A Frost Advisory is posted through 9 a.m., so anyone tending gardens, potted plants, or other tender greenery is urged to shield them from the cold this morning. Skies are expected to turn mostly sunny and breezy with a high near 63°F, but by Monday and Tuesday the pattern flips to something much warmer and wetter.
Frost Advisory This Morning
The Frost Advisory covering much of central Marion County and nearby areas remains in effect until 9 a.m. Sunday. With temperatures dipping into the mid 30s, visible frost is possible. The National Weather Service recommends covering or moving tender plants and holding off on new plantings for now, according to NWS Indianapolis.
Sunny, Breezy Today
For the rest of Sunday, expect mostly sunny skies and a high near 63°F, with southwest winds around 5 to 15 mph and gusts that could push into the mid 20s this afternoon. There is only a slight chance of a brief shower late in the day. Earlier reporting flagged the early morning frost concern and the fast shift to milder conditions later today, which you can revisit in frosty wake-up coverage.
Storm Risk Monday And Tuesday
By Monday, May 4, 2026, temperatures jump, with highs near 76°F and south-southwest winds picking up. Scattered thunderstorms may develop by afternoon and into the evening. The rain chance ramps up further Tuesday, May 5, with a higher likelihood of showers and thunderstorms and some spots potentially picking up around 0.5 to 0.75 inch of rain along with gusty winds, according to NWS Indianapolis.
Quick Planning Tips
Keep tender plants covered or moved inside until the Frost Advisory expires this morning, and bring potted plants indoors where you can. Looking ahead to Monday night and Tuesday, plan for rain by having a jacket or umbrella handy, secure any lightweight patio furniture or yard items, and check for updated forecasts before hitting the road.
