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.

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.

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…
