Oklahoma City is waking up clear and already warm Thursday, but the real story arrives this afternoon: temperatures are expected to reach 101 degrees, with the heat index climbing as high as 107. A Heat Advisory will run from noon through 9 p.m. as the city faces another dangerous stretch of summer heat.
Heat Peaks Thursday Afternoon
A slight chance of rain showers is possible between 7 and 10 a.m., but skies should turn mostly sunny afterward. The National Weather Service in Norman says heat-index values could reach 109 degrees in parts of the advisory area, with south winds around 7 to 10 mph.
That makes Thursday a poor day for long periods of strenuous outdoor work, especially during the afternoon peak. Drink plenty of water, take frequent breaks in air conditioning or shade, and check on older neighbors, relatives and anyone who spends much of the day outside.
Friday Stays Hot Before A Front Arrives
Friday will bring little immediate relief, with another high near 101 degrees and heat-index values up to 108. There is a 30% chance of showers and thunderstorms from about 7 a.m. to 4 p.m., followed by a smaller storm chance later in the day.
A front should push south through the region Friday, shifting winds toward the north and opening the door to cooler weather. Any storms that develop could produce strong wind gusts, so outdoor plans may need a backup option.
The change is more substantial than the earlier heat updates covered by Hoodline, with a noticeable weekend cooldown now in the forecast.
Weekend Brings A Welcome Cooldown
Saturday should be sunny with a high near 90, followed by a mostly clear night near 70. Sunday will stay sunny and reach about 91, giving Oklahoma City its best outdoor window of the weekend.
The cooler pattern will not last forever: highs are forecast to rise to 93 Monday, 96 Tuesday and 98 Wednesday. For the next several days, the safest bet is to finish outdoor chores early, avoid the afternoon heat Thursday and Friday, and save bigger plans for Saturday or Sunday.
