(00:00:00) Todays weather in Indianapolis - Friday - 15 May 2026 (00:00:37) What To Wear And Carry Today (00:01:17) Weekend Storm Warning (00:02:08) Indy 500 Qualifying Rain Risk (00:02:36) Record Heat Monday May 18 (00:03:38) Your Weekend Prep Summary Today is one of those genuinely nice Indianapolis spring days — and it's worth appreciating before the bottom drops out. Friday, May 16 opens at 66°F with scattered clouds, humidity at 58%, and a northwest breeze around 11 mph with gusts to 16. A 26% rain chance means you'll likely stay dry, roads are clear, and the commute looks smooth in both directions. A light jacket handles the morning chill; shed it by afternoon.But here's the full picture, because this weekend is a completely different story. High pressure slides east Friday night, pulling Gulf moisture deep into Indiana. Saturday and Sunday bring multiple rounds of showers and thunderstorms — with damaging winds as the primary threat. Storm timing is still uncertain, which matters especially if you're heading to Indianapolis Motor Speedway for Indy 500 qualifying on Saturday. Have a contingency plan; delays are possible.Then comes Monday, May 18. Indianapolis could touch 90°F — record territory for the Ohio Valley and a swing of nearly 25 degrees in under 72 hours. Early-season heat at that level is serious. If you or anyone around you is heat-sensitive, plan for shade, hydration, and minimal outdoor exposure during peak afternoon hours. Thunderstorm chances continue nearly every day into early next week as the warm, humid pattern gets established.The short version: enjoy today, prepare for storms this weekend, and get ready for potentially historic heat on Monday. Stay updated as storm timing sharpens — that's the biggest unknown heading into the weekend.This episode includes AI-generated content.
