Heat indices above 100°F will grip Norman through Labor Day weekend. Fans heading to OU's Friday night season opener face dangerous conditions on top of the scorching forecast.
The National Weather Service office in Norman said Sept. 2 that the heat wave blanketing Oklahoma will continue through the week and into the holiday weekend. Temperatures will stay well above normal for early September.
The NWS seven-day forecast showed a high near 98°F for Wednesday afternoon with a heat index as high as 101°F. Thursday's forecast called for a high near 97°F and a heat index up to 103°F. The agency warned that dangerous heat would persist across central and eastern states through Friday night.
That Friday night is game night.
The University of Oklahoma opens its 2026 football season against UTEP (University of Texas at El Paso) at 7 p.m. Sept. 4 at Gaylord Family–Oklahoma Memorial Stadium. KFOR reported Wednesday that the university is preparing for a heat-filled opener. Specific stadium heat-safety measures, such as misting stations or expanded medical staffing, had not been confirmed by OU Athletics as of Wednesday.
The 7 p.m. kickoff should spare fans from peak afternoon heat, but the NWS warned dangerous conditions would persist through Friday night. OU Athletics also released new game-day driving maps ahead of the opener, encouraging fans to use the routing maps instead of GPS, which does not account for game-day road closures, OKC Fox reported.
Weeks of above-average temperatures
The heat wave is not new. A heat dome stretching from the Rockies to the East Coast pushed temperatures above 100°F across Oklahoma, Texas, Kansas, Louisiana and Arkansas over the past week, CNN reported Aug. 30. Overnight lows have been running 10 to 15 degrees above average, limiting the body's ability to cool down between daytime peaks.
Oklahoma State Climatologist Gary McManus told KGOU in mid-August that the number of triple-digit days across the state was already well above average. "It's a little bit of a summer on steroids," McManus said.
The Weather Channel reported Wednesday that the southern Plains will see triple-digit temperatures throughout the holiday weekend, with heat indices also reaching triple digits.
Local strain
The Oklahoma Department of Environmental Quality issued an air quality alert for the greater Oklahoma City metro area on Aug. 28. Norman officials have been monitoring water demand throughout the summer. The city's supply was stable as of Aug. 21, but continued high demand could prompt restrictions, according to the Norman Transcript.
NWS forecasts showed no clear break in the heat through the end of the holiday weekend. Residents and game-day visitors can check the latest conditions and heat-safety guidance at weather.gov/norman or call 911 for heat-related emergencies.
