A heat advisory is in effect for Indianapolis until 8 p.m. on July 29. Heat indices will spike as high as 107 degrees on Monday and Tuesday afternoons. Overnight temperatures will provide little relief from the sweltering daytime heat, dipping only into the mid-70s.
“That’s even almost just as dangerous as the hot temperatures, especially for those vulnerable populations without adequate AC,” said National Weather Service meteorologist Cody Moore.
Moore suggested limiting time outside, wearing light-colored clothing and using a cooling center during the day if needed.
“This is above average for this time of year, but we expect this. It’s July, this is not anything out of the ordinary,” Moore said. Humidity increases in part at this time of year because of the phenomenon of “corn sweat,” he added.
Isolated thunderstorms will provide some temporary relief amidst the sweltering weather on July 28 and July 29. But as the sun comes back out in the afternoons, the residual moisture from those storms will make the air feel very humid.
A flood warning is in effect for Marion County until 11:15 a.m. on July 28.
The heat wave should break on July 30, when a storm system will move into the area and knock temperatures down to more tolerable levels for at least a few days.
On July 31, the high temperature will be a modest 78 degrees.

How to stay cool during extreme heat
The city encourages Hoosiers to keep the following safety tips in mind over the next few days.
Stay hydrated. Drink plenty of water.
Check on relatives and neighbors, especially the elderly and those without access to air conditioning.
Avoid strenuous outdoor activities. If possible, delay outdoor chores until the evening hours.
When working outside, wear light, loose-fitting clothing. Take frequent breaks in the shade or an air-conditioned room.
Know the signs and symptoms of heat exhaustion or heat stroke. If you or someone you know experiences signs of heat stroke, call 911 and take immediate action to cool off the person until help arrives.
Never leave children or pets unattended in a vehicle.
Bring pets indoors and ensure they have plenty of water to drink. The city said pets are not to be outside unsupervised when the temperature is higher than 90 degrees or a heat advisory is in effect.
Consider carrying an umbrella for immediate shade while outside.
Dial 211 or 866-211-9966 to reach Indiana 211 for non-emergency resources.
