Tulsa begins Monday with a warmer but more hazardous weather setup, as breezy southerly winds, dry air, and mid-40s temperatures combine to increase fire weather concerns across northeast Oklahoma and parts of northwest Arkansas. While conditions do not rise to extreme levels, the National Weather Service urges residents to use caution throughout the afternoon.
Temperatures across the Tulsa metro are expected to climb into the mid-40s, providing a noticeable warm-up compared to recent cold mornings. However, relative humidity values falling between 25 and 35 percent, paired with south to southwest winds of 20 to 25 mph, will create an environment favorable for grassfires—especially in open and rural areas.
According to fire weather guidance, grassland fire spread rates could reach 80 to 110 feet per minute in the most vulnerable locations. These conditions are most likely to peak during the Monday afternoon hours, when winds are strongest and humidity is lowest. The areas of greatest concern include northeast Oklahoma and far northwest Arkansas, where cured grasses can ignite and spread quickly.
Officials emphasize that this is a limited fire spread potential, not a high-end outbreak, but even small sparks could cause problems under these conditions. Residents are advised to properly extinguish cigarettes, avoid burning debris, and use caution with welding or equipment that could produce sparks. Driving or parking vehicles on dry grass should also be avoided.
Winds are expected to gradually ease later Monday evening, reducing the fire threat overnight. Still, Monday afternoon remains the critical window for heightened awareness.
In summary, Tulsa’s Monday weather brings mild temperatures but elevated fire danger, making it important for residents to stay alert and practice fire-safe behaviors as warmer, drier conditions briefly take hold.
