Statewide Discussion:

Forecast guidance through the week has strengthened pointing toward the development of strong fire weather indices coupled with very dry fuels across much of the state setting the stage for a fire environment that is receptive and supportive of rapid fire growth. Near critical indices today will progress to anticipated critical fire danger indices on Sunday ahead of a cold front. A Fire Weather Watch is in place for the western Panhandle for Saturday with a much broader Fire Weather Watch effective for Sunday along and west of US 177.

Today, rapidly rising temperatures combined with only moderate overnight moisture recovery will facilitate dry, receptive fuels and a somewhat extended burning period today.

Panhandle/Northwest: 67°-75° with relative humidity values dropping into the 9-17% range will result in very receptive fine fuels of 4-5% encouraging probability of ignition nearing 70%. Southerly winds 10-15 mph gusting to 20 mph translate into rates of fire spread near 200 ft./min. in fuels typical of the area. More rapid rates are probable where winds are aligned with topography.

Western Oklahoma (west of I35): 59°-69° with relative humidity values 13-26% driving fine-dead fuel moisture into the 5-6% range. Grass fuels will support rates of fire spread near 200 ft./min with south winds 15-20 mph and gusts in excess of 25 mph. Timber fuels will be less of a barrier to fire spread given the preceding drying conditions, and support rates of fire spread in the nearer to 20 ft./min. with flame lengths 5-6ft. at the head fire.

Eastern Oklahoma: Temperatures in the mid-50°’s and relative humidity values 28-37% will lead to some improvement of fine fuel moisture compared to yesterday afternoon, but still fall widely into the 7% range supporting moderate fire behavior. South winds this afternoon 5-15 mph with some gusts near 20 mph will deliver moderate rates of fire spread.

Elevating fire danger through the weekend is a concern especially across western and parts of central Oklahoma. Given the current forecast, Sunday is poised to present the most significant fire danger of the season so far. With many sites in western Oklahoma 100 days or greater separated from wetting rains and negligible amounts in the last month composite fuel moisture is lagging. Fire weather, in initially forecast with temperatures in the upper 60°’s with relative humidity values in the teens and twenties across western Oklahoma will promote readily receptive fuels. Stout southwest winds with expectation of gusts in excess of 40 mph will result in rapid rates of fire spread ahead of the wind shift associated with the approaching cold front.

Special Note to Fire Fighters: County Wildland Task Force Resources should assess their readiness anticipating the need for mutual-aid requests.
