Indianapolis woke up to a muggy, restless start on Wednesday, April 15, 2026, with temperatures stuck near 70°F and southwest winds already on the move. The warm, humid setup is priming the atmosphere for another round of showers and thunderstorms later today, with afternoon highs expected to climb to around 84°F for a brief taste of early summer.
Afternoon Into Tonight
Showers and thunderstorms are expected to fire up after about 10 a.m. and may keep at it through the evening on Wednesday. The high should still reach near 84°F, with southwest winds around 10 to 14 mph and gusts that could spike up to 28 mph. Any storm that rolls through could briefly tap into those stronger gusts. Most spots that see storms can expect around a quarter to a half inch of rain, with the overall chance of precipitation sitting near 70%.

Severe Risk And Overnight Rounds
This evening carries a heightened risk for a few strong to severe thunderstorms, mainly from damaging straight-line winds, and an isolated tornado cannot be ruled out in a couple of locations. Storm coverage is expected to increase overnight, with lows holding in the mid to upper 60s and pockets of heavier rain. Where the more persistent bands set up, totals could reach between a half inch and three quarters of an inch. The setup and the damaging wind threat were outlined in earlier coverage.
Weekend Outlook And What To Expect
Friday is shaping up as the break in this unsettled pattern, with mostly sunny skies, dry conditions, and very warm highs near 83°F. That looks like the quietest day of this stretch. Another system is set to move in on Saturday, bringing renewed chances for thunderstorms. Stronger wind gusts near 35 to 40 mph are possible with any organized line or complex of storms. Once that front clears, Sunday turns noticeably cooler, with highs in the mid 50s and the potential for near-freezing lows in some sheltered spots by early next week.
How To Stay Ready
Make sure your phone is set to receive weather alerts this afternoon and evening, and have a quick backup plan to move outdoor activities inside if storms approach. It is a good idea to secure patio furniture, grills, and tarps so they do not go flying in the gusts. Avoid driving through flooded streets, even if the water looks shallow, and be ready for brief power interruptions where the stronger storms hit. If a severe weather warning is issued for your area, move to a small interior room away from windows and stay there until the storm has passed.
