INDIANAPOLIS, Ind. – Gray skies, wet streets, and a stiff east wind set the tone across Central Indiana early Wednesday as a blustery fall system drifts east. The damp start marks a brief midweek slowdown before a sharp cool-down arrives just in time for Halloween night.
According to the National Weather Service in Indianapolis, scattered light rain will persist through early Thursday before skies begin to clear. Highs today hover in the low 50s, but cooler air slides in behind the departing low-pressure system. Winds will shift north at 10–15 mph, gusting to 25 mph by Thursday afternoon — enough to drop wind chills into the 40s across Marion, Hamilton, and Boone Counties.
Friday brings calmer weather but a noticeable chill. Highs near 57°F will fall quickly after sunset, with trick-or-treat temperatures dipping into the low 40s. Costumes will need layers, and parents should plan for brisk air and dry but cool streets. The National Weather Service expects mostly clear skies Friday night, ideal for outdoor events but chilly enough to signal fall’s final turn toward early winter.
By Saturday, another high-pressure ridge takes over, keeping skies bright but temperatures steady in the mid-50s. Sunday remains mild and breezy, though a few showers could return by late evening ahead of a warmer Monday push. Longer-range outlooks hint at a colder start to November — the kind that could bring Indiana’s first flurries before mid-month.
After all, the chill of winter isn’t far behind.
