Indianapolis is starting Thursday with clear skies and temperatures around 66 degrees, a welcome reset after Wednesday’s storms. Mostly sunny conditions will push the temperature near 82 degrees before a cooler, mostly clear night settles in.

Sunny Thursday, Cooler Night

The National Weather Service expects mostly sunny skies Thursday, with light west-northwest winds between 2 and 6 mph. A little patchy fog may linger early in spots, but it should burn off quickly as the morning warms up. Rain chances remain minimal, staying below 10% through the afternoon.

Dry Stretch Through Saturday

Thursday night will be mostly clear, with a low near 62 degrees. Friday brings full sunshine and a high around 81, followed by another mostly clear night near 62. Saturday turns warmer at about 85 degrees under mostly sunny skies, making for a solid outdoor-weather encore.

Heat Builds Sunday And Monday

The bigger shift arrives Sunday, when temperatures climb near 89 degrees and southerly winds could gust to 18 mph. Monday is expected to reach 91 degrees, with southwest gusts up to 20 mph, while Tuesday may peak around 92. The forecast discussion says hotter and more humid air will dominate from Sunday into early next week.

Small Shower Chance Returns Wednesday

A slight chance of rain showers develops late Tuesday night, with a 20% chance of precipitation after 2 a.m. Wednesday. Wednesday could bring a few showers or thunderstorms, but mostly sunny skies and a high near 91 degrees are still expected. No watches, warnings or advisories are listed for Indianapolis in the current forecast.
