Tulsa, Oklahoma – Warm temperatures and strengthening southerly winds are raising grassfire concerns across eastern Oklahoma and northwest Arkansas as the region heads into the early part of the week, with conditions becoming especially risky during the afternoon hours.
According to the National Weather Service in Tulsa, temperatures will climb into the mid to upper 50s with relative humidity dropping into the 30 to 45 percent range. South winds of 10 to 15 mph, with gusts up to 25 mph, will create an environment favorable for rapid grassland fire spread, particularly Sunday and Monday afternoons. Fire spread rates could reach up to 120 feet per minute in the most vulnerable areas.
The highest concern Sunday afternoon is across northeast Oklahoma, expanding Monday to include much of eastern Oklahoma and far northwest Arkansas. Officials urge residents to properly dispose of cigarettes, avoid parking vehicles on dry grass, and use caution with any equipment that could spark a fire. Even small ignition sources could lead to fast-moving grassfires under these conditions.
Looking ahead, near-record warmth is expected to persist through midweek before rain chances increase late Wednesday night into Thursday. A slight chance of thunderstorms is also possible, depending on how much instability develops. Current rainfall projections suggest beneficial moisture, especially from southeast Oklahoma into northwest Arkansas, though timing and totals may still change.
Fire weather concerns remain elevated until meaningful rain arrives, and additional updates are expected as conditions evolve.
