Indianapolis started Saturday under clear skies and a brisk 43°F at Indianapolis International Airport, but the chill is not sticking around for long. Sunshine is set to lift afternoon temperatures into the upper 60s, with a much warmer air mass moving in for Sunday, April 12, 2026.
Sunny Saturday, Warm Sunday
On Saturday, April 11, 2026, look for plenty of sun and a high near 68°F. A few far northern spots could slip into the mid-30s before sunrise, which may be just cold enough for some patchy frost. By Sunday, April 12, 2026, the pattern flips to early-summer mode, with highs in the lower 80s and south winds of 8 to 18 mph, plus gusts that could reach 30 to 35 mph across the northern half of the metro. No watches or warnings are in effect this morning, according to the NWS Indianapolis.
Plan For The Afternoon
Winds stay on the lighter side early in the day, which makes it a convenient window to haul potted plants indoors and secure any patio furniture before the breeze picks up later. Temperatures will climb steadily through the afternoon, setting up an easy day for outdoor errands, a walk around the neighborhood, or a quick park run.
Storm Chances Return Next Week
Rain makes a comeback Sunday night into Monday, April 13, 2026, when showers and a few thunderstorms are possible. The main trouble spots, though, look to be Tuesday and Wednesday, April 14 to 15, 2026, when forecasters say strong storms are possible, with gusty winds and pockets of locally heavy rainfall. If you have outdoor plans in the middle of the week, keep a weather app handy and be ready to duck inside if storms roll through, per the NWS Indianapolis.
