Indianapolis woke up in a steam bath Sunday, with thick, muggy air, temperatures hovering near 70°F, and fog cutting visibility in spots. Drivers heading out early should plan for pockets of dense fog through mid-morning that could briefly knock visibility below a mile in some neighborhoods.
Heat Advisory And What To Expect
If the morning haze feels rough, it is just the warmup. The National Weather Service has slapped a Heat Advisory on Marion County and much of central Indiana from noon Monday, June 29, through 8 p.m. Thursday, July 2. Daytime highs are expected to climb into the low-to-mid 90s, with overnight lows stuck in the mid-70s. Heat index values could reach 105-108°F. The most punishing stretch looks to be Monday afternoon through Thursday, with little relief after sunset, so stay alert to outdoor heat risks, according to NWS Indianapolis.
Where To Cool Off
Local TV station WRTV has rounded up Indy Parks family centers, Indianapolis Public Library branches, pools, and splash pads that residents can use to beat the heat. You can call 2-1-1 to find the nearest options and check their hours. Anyone who relies on outdoor work should build in frequent breaks, seek shade, and hydrate heavily during the midafternoon peak, when the heat index will be at its worst.
Foggy Morning, Sunny Afternoons
Low clouds and patchy fog are expected to lift by late morning as light mixing kicks in, giving way to partly sunny skies and a high near 87°F on Sunday. Winds should stay light and rain chances remain low, although a stray shower cannot be ruled out far to the southwest.
Plan Ahead
From Monday through Thursday, it is not the week to play tough with the sun. Reschedule strenuous outdoor activities for early morning or evening and drink plenty of water, as prolonged exposure could lead to heat illness. Check on elderly neighbors and anyone without air conditioning, and never leave children or pets unattended in parked cars during hot weather.
