Statewide Discussion: 

Cooler temperatures are in store through mid-week on the heels of a cold front until a climb back into more seasonal heat develops later this week. Precipitation chances will linger today in portions of eastern Oklahoma as well as the Oklahoma Panhandle although dry conditions will prevail into the workweek until slight chances of storms late in the week across portions of western Oklahoma enter the forecast. Hot and dry conditions last week spurred increased rates of evapotranspiration, decreasing both live fuel moisture values and upper-level soil moisture especially in portions of southwestern Oklahoma and areas along and just west of I-35. 

While no significant fire weather or fire danger is expected this week, grass dominated fuels will be more receptive especially where cool-season species have been pushed into dormancy. In the forecast period, fire weather is rather unimpressive with moderate afternoon relative humidity values, respectable overnight moisture recovery and the lack of excessive winds expected. Rates of fire spread in grass dominated fuels during peak burning in those driest areas will generally be less than 75 ft./min with flame lengths averaging less than 10 ft. at the head fire providing for very good probability of initial attack success. Obviously, expect potential increased fire behavior where the combination of extended separation from wetting rains and wind/topography alignment is present. Timber-litter fuel types are expected to exhibit minimal to moderate fire behavior given the current live fuel moisture profile along with canopy shading/sheltering.

The slight chance of storms in western Oklahoma contained in the current forecast late in the week does merit consideration for the potential for lightning ignited fires – especially in areas with elevated topography across southwestern Oklahoma. Should the forecast merit, an updated situation report will be issued later in the week to address the potential as forecast confidence improves with regard to storm chances, precipitation amount and lightning activity level.

Burn Ban Status: No Burn Bans presently in effect.
