Oklahoma City is starting Sunday, August 16, under clear skies and a Heat Advisory, with temperatures expected to surge to 104 degrees and the heat index reaching 109. A few storms may pop late in the afternoon, but the bigger story is a dangerous stretch of heat that will continue through the week.
Heat Peaks Sunday Afternoon
The Heat Advisory remains in effect until 7 p.m. Sunday, August 16. According to the National Weather Service Norman, a slight chance of showers and thunderstorms arrives after 4 p.m., with a 20% chance of rain.
Most of the day will stay sunny, with southwest winds around 12 mph. Storms that develop near a nearby front could produce isolated damaging winds, so anyone with late-day outdoor plans should have a quick route to shelter.
Monday Offers Little Relief
Temperatures dip slightly Monday, August 17, with a high near 99 and a heat index as high as 104. A slight chance of showers and thunderstorms returns after 1 p.m., with another 20% chance of rain before storms taper off early Tuesday.
Monday night will be mostly clear with a low around 76. The brief break will be modest, however, as the forecast calls for triple-digit heat to return quickly.
Triple-Digit Heat Runs Through Saturday
Tuesday, August 18, is forecast to reach 104 degrees, followed by a high near 105 Wednesday, August 19. Highs should remain near 100 Thursday, Friday and Saturday, while overnight lows mostly stay in the mid- to upper 70s, limiting relief after sunset.
Rain chances fall to nearly zero by Tuesday and remain low through the weekend. In other words, Oklahoma City is looking at more sun than storms and several days when the pavement, car interiors and exposed skin will all feel the difference.
Plan Around The Hottest Hours
Residents should drink plenty of fluids, take breaks in air conditioning and avoid extended time in direct sun during the afternoon. The City of Oklahoma City maintains extreme-heat resources and cooling-center information, including guidance for checking on vulnerable relatives and neighbors.
