Tulsa, OK – Oklahomans should brace for a late-summer heat surge as temperatures climb into the mid-90s Friday, September 12, with heat index values near 100 degrees. Commuters along I-44, U.S. 75, and major Tulsa roadways should take extra care, as the combination of sun, heat, and lingering moisture can increase fatigue and heat-related stress.
According to the National Weather Service in Tulsa, a ridge of high pressure will keep skies mostly clear while locking in above-average warmth through at least Tuesday. No severe storms or flooding are expected, but the extended stretch of dry, hot weather raises health and safety concerns. Residents are urged to limit strenuous outdoor activity during peak afternoon hours, stay hydrated, and check on vulnerable neighbors and pets.
Friday will bring plenty of sunshine and a high near 94 degrees. The weekend continues hot, with Saturday and Sunday both pushing into the mid-90s under mostly sunny skies. Overnight lows in the lower 70s will provide only slight relief.
Travelers heading through eastern Oklahoma into northwest Arkansas should also plan for the heat. Emergency crews warn that car breakdowns and heat illness are more common in prolonged hot, dry stretches like this one.
The heat holds into early next week, with Monday and Tuesday both reaching the lower 90s before a slight cooldown midweek. Officials advise monitoring local updates for any air quality alerts or extended advisories.
