Indianapolis is waking Tuesday to clear skies and temperatures near 57 degrees, with a sunny afternoon headed toward 79. Winds will stay light from the south-southeast, and the morning’s patchy fog risk should fade after sunrise. The quiet start is a brief pause before a warm midweek push and a much wetter turn late Thursday.

Sunny Tuesday, Warmer Wednesday

Tuesday night will be partly cloudy and cool, with a low around 57. Wednesday turns mostly sunny and warmer, topping out near 85 with southwesterly winds. The National Weather Service outlook remains dry through midweek.

Thursday Brings Summerlike Heat

Thursday looks partly sunny, with a high near 85. South-southwest winds of 6 to 13 mph could gust to 22 mph, so loose outdoor setups may need a little attention. The rain chance is 30% during the day, and rain chances continue after dark.

Storms Arrive Late Thursday Into Friday

A slight chance of showers begins Thursday evening, with showers and thunderstorms possible after 2 a.m. Friday. Friday brings a chance of showers and a high near 70. Hoodline’s Monday forecast already flagged late-week storms, but the newest outlook sharpens the timing and adds a bigger warm-up first.

Cooler, Showery Weekend

Rain may linger Friday night before Saturday brings a 40% chance of showers, with partial sunshine possible and a high near 68. Sunday rain chances linger, with partial sunshine possible. No watches, warnings or advisories are currently in effect for the Indianapolis area.

Falllike Air Arrives Monday

After the unsettled weekend, Monday should turn sunny as cooler, dry weather arrives.
