Statewide Discussion: 

Warmer and windier conditions are in store for today although fuel moisture values across most of Oklahoma are not expected to present much in the way of resistance to suppression. Numerous prescribed fires and controlled burns were conducted yesterday, and practitioners are encouraged to patrol and mop-up their work from yesterday ahead of increasing winds this afternoon. The highest fire danger today will reside in the western half of the Oklahoma Panhandle although storm potential may offset the threat. Increased potential in north-central and parts of northeastern Oklahoma where moderate rates of fire spread are expected as relative humidity values fall this afternoon.

Oklahoma Panhandle: There is a chance of thunderstorms today and some potential for lightning ignitions especially in the western half of the Panhandle. Precipitation may offset the threat, but temperature nearing 80° and afternoon relative humidity values as low as 23% will support receptive fine fuels if no precipitation is realized. Southwest winds sustained 12-18 mph gusting 30 mph will support moderate rates of fire spread in fuels typical of the area at 95-135 ft./min. with flame lengths at the head fire 7-13 ft. Any fire occurring in the vicinity of a thunderstorm will likely exhibit erratic fire behavior and shifting direction of spread based on outflow winds.

North-Central/Northeastern Oklahoma: Respectable overnight moisture recovery will delay development of fuel receptiveness, but temperature this afternoon 70°-75° and relative humidity values 30-38% will facilitate receptive fine-dead fuels ranging from 6% under clear skies to 8% where sky cover persists. South winds sustained 12-20 mph gusting this afternoon to 30 mph will support moderate to rapid rates of fire spread in horizontally continuous, dormant tall grasses. Rates of spread 160-230 ft./min. with flame lengths averaging 13-18 ft. should be anticipated at the head fire. Fuels are not expected to present much resistance to suppression, although soil moisture will likely limit engine and equipment access in many locations.

Elsewhere in Oklahoma, moderate fire danger is expected with relative humidity values above 35% in most locations halting fine-dead fuel moisture from tapping critical values in most locations. Initial attack efforts, in general are expected to be successful with a low probability of large fire occurrence or significant activity.

Very dry air will push into the western Panhandle tomorrow along with temperatures again nearing 80° elevating fire danger although rates of spread will likely be limited by generally light winds. Dry conditions through the day tomorrow are expected in Oklahoma with warm temperatures persisting. Fortunately, fine-dead fuel moisture are expected to remain outside of the critical range in most of the state as south winds wind up to 15-20 mph gusting near 30 mph yielding moderate rates of spread. Some precipitation chances develop tomorrow evening and again Friday when storm chances increase especially east. Dry conditions are expected to continue in the southwest although critical fire danger indices are expected to remain west of the OK/TX state line.

Burn Ban Status: No Burn Bans presently in effect.
