Statewide Discussion: 

A punctuated warming/drying trend will facilitate development of somewhat increased fire danger in Oklahoma today.  While significant wildfire activity is not expected, increasing initial attack activity is.  Predominantly dry conditions persist into Thursday although light wind speeds will serve to limit rates of fire spread. Rain chances on Friday evening may reduce fire danger across much of the state although require intentional monitoring with conditions Saturday afternoon presently pointing to potential enhanced fire danger in southwest Oklahoma with warm and windy conditions.
Today, temperatures will warm into the low- to mid-50°’s with clear skies following a cold start.  Good overnight moisture recovery in the east will delay development of fuels availability; however moderate overnight recovery in the west will facilitate receptive fuels by late morning.  Fine-dead fuel moisture this afternoon will settle at 6% across much of Oklahoma with potential for 5% observations in southwest, south-central and western Panhandle counties with afternoon relative humidity values 25-33%.  Winds will be southerly increasing into the afternoon – strongest in the western counties.  Fuels are not expected to exhibit much resistance to suppression providing very good opportunity for initial attack success.
Western Oklahoma – 51°-63°, 24-30% Rh, South winds 16-23 mph gusting to 30 mph in the late afternoon.  Native, grass dominated fuels will support rates of spread approaching 300 ft./min. with flame lengths 15-18 ft. at the head fire on fully established wildfires.
Eastern Oklahoma – 45°-54°, 27-35% Rh, South winds 5-12 mph limited gusts. Unsheltered timber litter will support active fire behavior although moderate rates of fire spread. Minimal resistance to suppression is expected.  Rates of spread in typical grass fuels 70-150 ft./min. with 8-14 ft. flame lengths.  Hardwood timber fuels will exhibit rates of spread 10-15 ft./min. with flame lengths averaging 3 ft. at the head fire.  Pine dominated timber litter should be expected to produce somewhat increased fire behavior.
Thursday will bring warmer afternoon temperatures for most of Oklahoma although a cold front pushing into parts of northern Oklahoma will support cooler temperatures than today.  Dry conditions will support fire activity although somewhat higher relative humidity values and lower wind speeds will result in less active burning conditions.  The highest fire danger will be present in the southwest quarter of Oklahoma where temperatures 65°-75° and relative humidity values 24-36% will encourage very receptive fuels.  Southerly winds around 10 mph with limited gusts will produce only moderate rates of fire spread facilitating continued probability if initial attack success.
Increased relative humidity values on Friday will retard fire danger from developing concern ahead of precipitation chances into the evening and overnight hours.  Again, there is potential for elevated fire danger concern to develop in southwest Oklahoma on Saturday, although potential for mitigating factors exist.  Therefore, another evaluation will be generated Friday morning following as the forecast gains confidence. 
Burn Ban Status:   No Burn Bans presently in effect.
