Today started thick and sticky in Indianapolis, with patchy fog and muggy, still air hanging over the airport and temperatures already around 75°F at about 5:35 a.m. There is not much relief coming today. Humidity and sunshine are expected to push highs near 95°F, with real‑feel values well over 100°F this afternoon. Overnight lows will stay in the mid‑70s across much of the city, so residents without air conditioning are being urged to plan ahead.
Foggy Mornings, Dangerous Afternoons
The patchy fog should burn off by mid‑morning, and then the sun takes over. Temperatures are expected to climb into the mid‑90s, while the humidity makes it feel significantly hotter. Southwest winds will be light, around 2 to 7 mph, which means very little breeze to cut the heat. An Extreme Heat Warning remains in effect through 8 p.m. Friday, July 3, and the combination of high heat and humidity raises the risk of heat‑related illness, according to NWS Indianapolis.
Cooling Options And Safety
For residents without reliable air conditioning, public cooling spots are key. Indiana 2‑1‑1 lists hundreds of options statewide, and local centers are being activated as the heat hangs on. The Marion County Health Department and local partners are urging people to check on older neighbors and those with medical needs. For help finding a site, you can call 2‑1‑1 or look up local guidance from WRTV. Officials are also stressing the basics: avoid strenuous outdoor work during the mid‑afternoon, and never leave children or pets unattended in parked vehicles, even for a short errand.
Storm Chances And The Holiday Weekend
The upper‑level ridge that has been baking the region is expected to start loosening its grip late in the week, which opens the door to scattered storms on Friday and through the holiday weekend. Saturday, July 4, is forecast to start mostly sunny, with a growing chance of showers and thunderstorms by midday and afternoon, around a 70% chance, and a high near 92°F. Anyone planning outdoor gatherings should keep an eye on the forecast, since storms could be locally heavy, according to NWS Indianapolis.
Practical tips remain straightforward: drink plenty of water, wear lightweight clothing, and schedule heavy yardwork or runs for the morning or evening instead of the peak heat. If you or someone you know has unreliable cooling at home, make a plan for where to go or call 2‑1‑1 for local options. If someone shows signs of heat stroke, call 911 immediately. Stay mindful of pets and outdoor workers, and check cooling center hours before heading out.
