INDIANAPOLIS, Indiana – A damp, gray start to the week will give way to drier skies and crisp fall air by Halloween. Wet leaves and slick pavement could slow commutes across Marion, Hamilton, and Hendricks counties Wednesday before a calmer pattern sets in late Thursday.
According to the National Weather Service in Indianapolis, showers are expected to increase through Wednesday afternoon as a broad disturbance tracks across the Ohio Valley. Winds will shift to the north-northwest by Thursday, bringing cooler and drier air. Rainfall totals should stay under a half inch, but brief heavier bursts may reduce visibility on I-70, I-65, and surrounding routes. Drivers should watch for wet leaves that can act like ice on curves and intersections.
The payoff comes just in time for Halloween on Friday—mostly sunny skies, light winds, and highs in the upper 50s. Evening temperatures near 50 will make for comfortable trick-or-treating and outdoor community events across central Indiana. To be fair, the region’s luck with mild Halloween weather doesn’t always hold this late in October, so residents may want to take advantage before the next chill.
Looking ahead, Saturday and Sunday bring partly sunny conditions with highs in the low 50s—ideal for raking leaves or setting up early winter decorations. However, long-range models hint at a colder push by early November, suggesting the first frosty mornings could return soon. After all, it’s late fall in Indiana, and the crisp turn toward winter isn’t far behind.
