Oklahoma City gets a brief break from the worst of the week’s furnace Monday, but “break” is doing some work: afternoon temperatures still climb to 96°F, with heat-index values reaching as high as 103. Skies stay mostly sunny, and a few storms may pop late in the day before Tuesday and Wednesday push back into the 104-to-106-degree range.

Storms Possible Before Evening

A slight chance of showers and thunderstorms lingers before 7 a.m. Monday, followed by a 30% chance this afternoon and evening. The better window in Oklahoma City appears to be from roughly 4 p.m. through 10 p.m., although rainfall should be spotty and totals are expected to stay below a tenth of an inch. Any storm that develops could produce a sudden, strong downburst, giving outdoor plans one more reason to keep an indoor backup handy.

Heat Builds Back Tuesday

Monday night falls only to around 76°F, with a chance of storms before 10 p.m. before skies clear. Tuesday turns sunny and hotter at 104°F, with heat-index values near 107, while Wednesday could reach 106°F under sunny skies. The National Weather Service says heat advisories will likely be needed again Tuesday and Wednesday.

Weekend Relief Looks Brief

Thursday and Friday offer a modest dip to around 99°F, but the relief is temporary. Saturday is expected to hit 100°F and Sunday 102°F, extending the same stubborn heat pattern Hoodline previously tracked in late July.

Plan Around the Hottest Hours

Move strenuous outdoor work to the morning or evening, drink water regularly and check on people and pets vulnerable to heat. Even if a storm briefly cools one neighborhood, overnight lows in the mid-70s to low 80s will offer limited recovery from the week’s heat.
