Oklahoma City starts Thursday clear and near 75 degrees, but the morning calm will give way to a high around 95. It is the last relatively manageable afternoon before triple-digit heat returns Sunday and hangs around through the middle of next week.

Thursday Offers One More Manageable Afternoon

Temperatures will climb through the 80s late this morning and reach the low 90s during the afternoon. Skies should stay partly sunny, with a north-northeast breeze of 3 to 7 mph and just a 4% chance of rain, according to the National Weather Service.

A few showers or thunderstorms could develop farther west and southwest in Oklahoma, but the Oklahoma City metro is expected to remain mostly dry. Tonight will be mostly clear, with temperatures falling to around 73 and heat-index values possibly reaching 97.

Heat Builds Again Before The Weekend

Friday turns sunny and slightly hotter, with a high near 96 and an overnight low around 74. Saturday reaches about 99 under sunny skies, while south winds of 8 to 13 mph could gust to 22 mph.

Sunday brings the first 101-degree high in the latest outlook, followed by another 101 on Monday. Overnight lows will only drop to the upper 70s, offering limited relief after sunset.

Triple-Digit Heat Continues Into September

The updated forecast keeps Oklahoma City near 101 degrees Tuesday and Wednesday, with mostly sunny or clear skies and little chance for rain. That extends the hot, dry run beyond Hoodline’s previous forecast update, which had Tuesday closer to 100 and did not yet carry the 101-degree stretch through Wednesday.

Plan Outdoor Time Around The Heat

No active watches, warnings or advisories are listed for the Oklahoma City area in the current forecast, but triple-digit afternoons can still bring heat illness risks. Schedule strenuous work and exercise for the morning or evening, drink water regularly, take breaks in air conditioning or shade, and check on older adults, children, neighbors and pets.
