Indianapolis woke up in a steam bath this morning, with 75°F at the airport, dew points in the mid-70s, and patchy fog making the air feel more like a sauna than a city. That soupy start is only the opening act for a brutal afternoon, as highs climb toward 95°F and the heat index spikes into the 105–110°F range. An Extreme Heat Warning is in effect from early Wednesday through Thursday evening, and residents are urged to limit outdoor time and keep a close eye on neighbors who might struggle in the heat.
Afternoon Heat And Weekend Outlook
That early fog should lift by mid-morning, giving way to mostly sunny skies and light southwest winds around 3–8 mph, which will not do much to cool anyone off. Highs of 95–96°F are expected today and again Thursday, with the heat index making it feel solidly in the low-to-mid 100s. By Friday, the upper-level ridge starts to flatten and the pattern turns more unsettled, with shower and thunderstorm chances rising to about 40% on Friday, around 50% on Independence Day, and the best odds for storms arriving on Sunday. According to the National Weather Service, the Extreme Heat Warning will remain in place as long as the dangerous mix of humidity and high temperatures sticks around.
How To Stay Safe
Health officials and forecasters are keeping the advice simple: drink plenty of water, avoid strenuous activity during the hottest afternoon hours, and stay in air-conditioned spaces as much as possible. Never leave children or pets in vehicles, even for a short time. For those who need short-term relief, cooling centers and public locations are available, and residents can call 2-1-1 or follow local guidance via WRTV to find a nearby spot. Check in on elderly neighbors, people without reliable cooling, and anyone who works outdoors, and employers are encouraged to shift heavy tasks to the cooler morning or evening hours.
Foggy Morning Commute
Drivers could run into stretches of reduced visibility, at times dropping to around a half-mile in spots this morning. Commuters should give themselves extra time, slow down on surface streets, and use low beams in thicker fog. Conditions are expected to improve after mid-morning as the fog burns off and the sun takes over, setting the stage for another scorching afternoon.
