Indianapolis woke up today to muggy, partly cloudy skies and temperatures already in the mid 70s, with a high near 94°F expected this afternoon. Forecasters say heat index readings will push into the triple digits this afternoon and through midweek, making prolonged time outside a risky proposition. An Extreme Heat Warning is in effect through Thursday, July 2, at 8 p.m., and overnight lows in the mid 70s will offer almost no break from the heat. Southwest winds around 5 to 9 mph are expected and will not do much to take the edge off.
How Hot And When
Expect a high near 94°F today with heat index values around 100 to 103°F this afternoon, with similar or even hotter readings on Wednesday and Thursday. Midweek, some spots could see heat indices climb above 105°F. Forecasters at the local office are calling for several straight days in the low to mid 90s with oppressive humidity, prompting what they describe as a recent upgrade in headlines for central Indiana, according to NWS Indianapolis. If you have to be outside, try to schedule work or exercise for early morning or evening and keep an eye out for signs of heat illness.
Cooling Centers And Safety
Indy Parks and other city services are opening family centers and pools as cooling options around town. If you do not have air conditioning, officials suggest heading to one of these sites or calling 2-1-1 to learn about local options. The city lists multiple family centers operating during daytime hours where residents can cool off, per Indy Parks. Bring water, avoid strenuous activity in the middle of the afternoon, and check in on older neighbors and anyone with health concerns.
Looking Ahead
The ridge of high pressure driving the heat is expected to start easing late in the week, with shower and thunderstorm chances increasing Friday and into the Fourth of July weekend. The forecast calls for scattered storms Friday with about a 30 to 40 percent chance and higher coverage into Saturday and Sunday. These storms could be locally heavy, but the exact timing is still uncertain, according to the local forecast office. Anyone with outdoor holiday plans should stay tuned for updates.
Practical Tips
Officials are urging residents to stay hydrated, use air conditioning when possible, and never leave children or pets in parked cars, even for a short time. Employers and event organizers are encouraged to shift physically demanding activities to the cooler parts of the day and to provide shade and plenty of water for workers.
