Oklahoma City is heading into Friday, September 18, with a forecast high near 98 degrees.
Heat Holds Through Saturday
Friday's outlook mentions prevailing south winds and an overnight low near 75. Saturday's forecast calls for a high near 98 degrees.
That means outdoor plans will come with plenty of sunshine but little relief from the heat. Drink water, take breaks from direct sun and save strenuous activity for the cooler parts of the day when possible.
Storms Arrive Sunday
The pattern shifts Sunday, September 20, with thunderstorms and rain chances mentioned for the day.
After the front, conditions are expected to be cooler and more seasonable.
Cooler Weather Follows
Monday's precipitation chances are expected to be closest to the cold front, with conditions becoming more seasonable afterward.
Dry Fuels Keep Fire Risk Elevated
Elevated fire danger is expected to continue through Saturday because drought-dried vegetation remains easy to ignite. Winds and humidity are not currently expected to meet traditional Red Flag criteria, and no watches or warnings are listed for Oklahoma City.
How unusual is the heat?
According to the National Weather Service Norman climate report, Oklahoma City reached 99 degrees Thursday, tying the daily record set in 1896. The agency lists the normal high for September 18 as 83 degrees and the daily record as 98, set in 1952, 1972 and 1997. Cooler, more seasonable conditions are expected after the front. Separately, Oklahoma Forestry Services says vegetation growth and accumulated fuels can increase wildfire risk when landscapes go without fire management, adding context to the elevated fire danger expected before the rain arrives.
