INDIANAPOLIS, IN – A calm, partly cloudy sky greets the city this early Monday, but change is already stirring over the Plains. Warm fall air will hold just long enough for one more mild day before a wet, unsettled pattern sweeps across central Indiana starting late Tuesday — the kind that soaks fields, slows traffic, and reminds Hoosiers that November is just around the corner.
According to the National Weather Service in Indianapolis, high pressure keeps today dry with highs near 64°F. But by Tuesday afternoon, clouds thicken and light rain begins spreading in from the west, marking the start of several damp, cooler days. Widespread showers are likely Tuesday night through Wednesday, with gusts up to 25 mph along I-70 and I-65. Rainfall totals could reach a half inch in some neighborhoods, though heavier pockets are possible.
Commuters should plan for slick roads Tuesday evening and early Wednesday, particularly around rush hour. Cooler air filters in midweek, pulling Wednesday highs down to the low 50s with brisk northeast winds.
By Thursday, conditions begin to clear, setting up a drier and sunnier stretch to end the week. Friday looks crisp and comfortable — perfect for Halloween decorating or trick-or-treat planning — with afternoon highs in the upper 50s.
Looking into the weekend, sunshine dominates but cooler nights dip near 40°F. Longer-range models hint at another push of colder air by early November — a subtle sign that a chilly November lies ahead.
