Statewide Discussion:

Fire weather elements will likely remain below warning criteria today; however fire danger should not be discounted given elevated weather elements and the current composite fuel moistures. Warm, dry and gusty conditions through the day will result in the potential for any established fire to grow rapidly presenting suppression challenges. Fire danger will decline this evening as with rain chances increasing in eastern and central Oklahoma, looking best in the southeast, and respectable moisture recovery in to the night. Additionally, sky cover pushing up from the south through the afternoon will reduce fire behavior in the southern counties.

The highest fire danger today will reside in the west-central, northwest and Panhandle counties where relative humidity values will settle in near 20% (the Panhandle counties may hit 16%) as temperatures warm into the upper 50°’s and lower 60°’s. Fine dead fuel moisture during the peak of the burning period will largely be 6% and south winds generally 15-20 mph gusting to 25 mph will generate rates of fire spread near 150 ft./min. with flame lengths 8-12 ft. on average in grass fuels typical of the area. Expect somewhat more impressive fire behavior on established fires where wind an topography are aligned.

In central Oklahoma, we expect to see temperatures near 60° with relative humidity values ranging from 26-33%. While fine-dead fuel moisture is not expected to fall below 7% in the broad area, persistent drying encourages the potential for increased fire behavior especially in woodland fuels where heavy fuel loading from past storms has accumulated. Grass dominated fuel of the area are expected to deliver rates of spread in the 100-135 ft./min range with flame lengths near 10 ft. (14-18ft. in rank, tall grasses) with south winds 12-18 mph and gusts nearing 25 mph. Timber fuels will deliver fire behavior with rates of spread of around 20 ft./min. but flame lengths nearing 8 ft.

Eastern Oklahoma will see temperature rise to above 60° with relative humidity values dropping below 30% ahead of sky cover pushing in that will buffer fine-fuel moisture. South winds 10-15 mph with gusts 15-25 mph will produce moderate rates of fire spread in fine fuels. Very low moisture values in the larger diameter fuels will likely result in fire behavior that is excessive for the season and require longer periods of mop-up.

Rain chances for this evening have improved in both probability and coverage; however forecast amounts are unimpressive. Opportunity in present for a wetting rain east of Highway 69 this evening. Lackluster amounts in central Oklahoma and western Oklahoma continuing to build dryness will hold the fire danger concern front and center. However, fire danger on Sunday is expected to be moderated with slightly cooler temperatures, improved atmospheric moisture and sky cover limiting relative humidity from driving fine fuels into values of concern.
