Sunday is expected to be mostly sunny in Oklahoma City, with temperatures climbing to around 99 degrees. A Heat Advisory was in effect from 1 p.m. to 7 p.m. Friday as dangerous heat spread across the region.

Near-100-Degree Heat Arrives Sunday

The forecast calls for mostly sunny skies and light south winds Sunday, with a high near 99 degrees. A slight chance of showers is possible Sunday afternoon, but no specific probability is provided here.

The Friday advisory covered portions of central Oklahoma, where the heat index reached as high as 109 degrees. This follows the earlier Labor Day outlook from Hoodline.

Monday Brings More Heat, Little Relief

Labor Day will look much like Sunday, with sunny skies and a high near 100. Rain chances rise slightly over the weekend and early next week, but no specific Monday timing is provided. The overnight low will be in the upper 70s, continuing a stretch of unusually warm nights that can make it harder for the body to recover from daytime heat.

Tuesday is expected to reach near 99 degrees, while rain chances remain close to zero through Friday.

Rain Chances Remain Low Through Friday

The forecast keeps rain chances close to zero through Friday; details for Thursday through Saturday are not specified here.

Heat Safety Remains Important

According to Oklahoma State Department of Health data, 141 heat-related deaths were recorded in Oklahoma from 2013 to 2022.

Residents should drink plenty of fluids, limit strenuous outdoor activity during the hottest part of the day and check on older adults, children, neighbors and pets. For local information, visit the City of Oklahoma City.
