Statewide Discussion:

Fire danger will be increasing this afternoon and then climbing again Saturday as warm, dry and gusty winds ahead of a cold front ramp up fire weather concerns on top of very dry fuels. Strong potential for Red Flag Warning criteria to be met Saturday afternoon in parts of western and Panhandle counties.

Cooler temperatures this morning have prompted respectable overnight moisture recovery in fine, unsheltered fuels; however residual fuel dryness and falling relative humidity values will highly receptive fine-dead fuels by noon and relative humidity values falling below 30% in all but some locations along the Arkansas border.

Western Oklahoma: Relative humidity values around 17% in the Panhandle to 25% along the Hwy. 183 area will encourage fine fuel moisture values of 6% with 5% probable further west as temperatures increase into the 50°’s. Southwest winds this afternoon 10-15 mph with some higher gusts will deliver moderate rates of fire spread.

Central Oklahoma: Temperatures in the low to mid-50°’s, clear skies and lowering dew point temperatures will deliver relative humidity values in the 24-29% range and fine-dead fuels of 6-7% this afternoon. Rates of fire spread will be largely limited by wind speeds 5-10 mph.

Eastern Oklahoma: Timber fuels in the area have been increasingly exhibiting fuels-driven fire behavior indicative of drought influenced large fuel moisture with the most notable observations in southeast Oklahoma. Relative humidity values will settle in around 30% this afternoon with some locations dropping below that value during the peak of the burning period. Temperatures in the low to mid-50°’s and relative humidity around 30% will hold fine fuel moisture above critical values; however larger fuels are expected to burn with intensity posing increased mop-up demands.

Shifting attention to Saturday, an approaching cold front will spike fire danger ahead of some potential for precipitation concentrated in eastern Oklahoma. Critical fire danger indices are likely to be in place across western Oklahoma with high and very high fire danger conditions across the state. Warm temperatures, gusty south-southwest winds and very dry fuels will encourage the potential for rapid fire growth further enhanced with strong ventilation rates. Established fires will have the potential to develop into large/significant incidents with focus on far western, northwestern and Panhandle counties.

Rates of fire spread in western Oklahoma could at times eclipse 200 ft./min with 12-16 ft. average flame lengths. In central Oklahoma, rapid rates of fire spread should be expected on any fire escaping initial attack along with problematic fire behavior where brush and Eastern redcedar are present. Pine dominated fuels in the east will have a tendency to transition into canopy fuels anomalous to seasonal expectations.
