Tulsa, Oklahoma – Fire weather concerns are increasing across northeast Oklahoma as dry air and gusty winds create near critical conditions, especially west of Highway 75 through Wednesday and Thursday.
The National Weather Service in Tulsa reports that relative humidity values will drop as low as 15 to 25 percent during the afternoon hours, while west to southwest winds increase to 15 to 25 mph with gusts between 30 and 35 mph. These conditions significantly enhance the potential for rapid grassland fire spread, particularly along and west of US-75, including areas near Bartlesville, Pawhuska, and Okmulgee.
On Wednesday, the highest fire danger is expected west of Highway 75, where dry fuels remain in place due to limited recent rainfall. South to southwest winds of 10 to 15 mph, gusting to 25 mph, combined with humidity between 15 and 20 percent, will support elevated fire behavior.
Conditions worsen Thursday afternoon as winds strengthen and shift gradually from west to northwest after sunset. The combination of continued dry vegetation, low humidity, and stronger gusts may lead to near critical fire weather conditions across a broader portion of northeast Oklahoma, including areas near Tulsa, Muskogee, and Miami along I-44 and US-69.
Any fires that develop could spread quickly and become difficult to control. Outdoor burning is strongly discouraged, and residents should avoid activities that could produce sparks, such as welding or dragging chains along roadways.
Officials urge residents and travelers along Highway 75, I-44, and surrounding rural routes to remain vigilant. Fire crews may face rapidly changing conditions through Thursday evening as wind directions shift and gusts remain strong.
