Statewide Discussion: 

Portions of northeastern Oklahoma and the Oklahoma Panhandle have received wetting rains within the previous seven days while much of the state is now 13-38 days separated from wetting rains resulting in a gradual shift toward more available fine fuel. In general, wildfires are exhibiting little resistance to control with successful initial attack efforts expected. However, some potential for lightning ignitions will be present this afternoon and evening in western Panhandle focused in Cimarron County.

Cimarron County – Thunderstorm chances increase today into the overnight hours with Lightning Activity Level pointing to the potential for widely scattered storms, light to moderate rainfall, and infrequent lightning (6-10 cloud to ground strikes in a 5 min. period). Forecast rainfall amounts less than 0.05” outside of the widely scattered storms are expected indicating some potential for lightning ignition and holdover. With no critical fuels or general fire weather in the forecast, anticipated fire behavior is not expected to be overly impressive. Although, attention does need to be given to outflow winds from passing storms. Should lightning ignitions occur, firefighters should expect fire behavior in grass dominated fuels to exhibit head fire rates of spread 35-100 ft./min. with flame lengths 6-11 ft. in grass dominated fuels.

Statewide – A good portion of Oklahoma is now 13-38 days separated from wetting rains with gradual increasing fuel receptiveness. Fuels and weather elements in the near-term do not support any significant fire activity although a slight increase in initial attack activity is anticipated. Again, resistance to control is minimal supporting very good probability of initial attack success. Other than an opportunity for widely scattered showers/storms Sunday into Monday, dry conditions are expected in the current forecast period. During peak burning conditions on a daily basis, fire behavior in grass dominated fuels will generally be less than 50 ft./min. with flame lengths 3-8 ft. In those driest areas of the state where continuous, available fuels are present some increased fire behavior should be expected.

The Oklahoma Wildfire Situation Report will be updated Monday, July 29 unless fire occurrence or conditions deviate from forecast.

Special Note to Firefighters:

Thunderstorms that pass in the vicinity of an active fire have the potential produce strong, gusty outflow winds that often result in erratic fire behavior. Firefighters should monitor fire environment conditions for the build-up of cumulus clouds, changes in wind speed and direction, and changes in fire behavior.

 Thunderstorms will produce outflow winds that generally intensify as a storm matures and will change the direction of fire movement as they pass. A storm passing directly over a fire may very likely prompt in increase in flame length and rate of spread in all directions.

Communicate changes in fire weather and behavior.

Insure that Escape Routes and Safety Zones are

Clearly identified.

Reinforce the anchor point and established control lines ahead of the storm arrival to diminish the potential of a blow-up

Burn Ban Status: No Burn Bans presently in effect
