Statewide Discussion:

Red Flag Warnings in effect today across Oklahoma with very low relative humidity and strong/gusty northwest winds. Fires that start will likely grow quickly and fires that become established will exhibit very rapid to extreme rates of fire spread. Poor overnight moisture recovery in northwestern, northern and areas of central Oklahoma will facilitate early development of critically low fine fuel moisture that will sustain through the day. The remainder of the week is forecast to be dry with persistent fire danger in place.

Statewide, northwest to west-northwest winds 20-30 mph with gusts near 50 mph in much of western Oklahoma and areas along and north of I-40 in the eastern half of the state. Temperatures will max out this afternoon on the upper 50°’s to mid-60°’s with relative humidity values 8-13% in the Panhandle, 13-18% in the western half of the state and 15-21% in the eastern half of the state. With little to no sky cover, fine fuel moisture values will range from 3-5% in Oklahoma. Given the poor to marginal overnight moisture recovery values in western and portions of central Oklahoma, anticipate rapid development of fine fuel receptiveness coupled with aggressive burning conditions persisting into the evening.

Fire behavior today on any established fire will exhibit extreme rates of fire spread in fine, flashy fuels and problematic fire behavior in grass/brush fuels including juniper, sagebrush and mesquite. Single and group tree torching should be expected especially where rank grass fuels transition with juniper (redcedar).

Special Note to Firefighters: Frontal assault on any going fire is strongly discouraged with expected fire behavior that includes very rapid to extreme rates of fire spread and excessive flame length. Wet soils in central and eastern Oklahoma continue to pose a tactical risk to firefighters. Scout access prior to committing engines and equipment. Attack from the black and avoid committing engines where they may become stuck in unburned fuels risking burnover.
