Statewide Discussion: 

Elevated fire danger concern will be present today across much of Oklahoma with potential for an increase in initial attack activity with warm temperatures and gusty south winds.  Dormant fuels statewide will support active fire behavior today although minimal resistance to fire suppression efforts is anticipated.  The driest fuels remain centered in southwest Oklahoma expanding up the western tier of counties as well areas generally south of I-40 and west of I-35.  Recent precipitation in the eastern two-thirds of the Oklahoma Panhandle and far northwest counties has alleviated the build-up of concern that was developing, although Energy Release Component values in Cimarron County continue to gradually increase.
Today, cool temperatures this morning will warm into the 60°’s this afternoon with afternoon relative humidity values supporting receptive fuels.  Burning conditions should be expected to develop mid-day with only moderate overnight moisture recovery.  Gusty south winds will prompt moderate rates of fire spread in most locations.  The highest fire danger indices today will reside west of a line from Woods County to Cotton County although unsheltered, fine fuels will be receptive statewide.
Western Oklahoma - 59°-66° this afternoon with relative humidity values 24-30% (18% in the western Panhandle) under clear skies facilitating fine-dead fuel moisture values 5-6% with a few sites in Cimarron County tapping 4% during the peak of the burning period.  Southerly winds 16-23 mph gusting 25-30 mph will drive rates of fire spread in uniform, native grasses of 210-300 ft./min. and 15 ft. flame lengths at the head fire.  
Central/Eastern Oklahoma - 57°-64° during the peak of the burning period with relative humidity values 29-39% and fine-dead fuel moisture values 6-7% with some 5% observations likely at a few locations.  Southerly winds 10-18 mph gusts 15-25 mph will drive rates of fire spread in grass dominated fuels 115-200 ft./min. with 8-12 ft. flame lengths.  Timber fuels in most locations will deliver greatly reduced fire behavior and in many locations serve as a barrier to fire spread unless pine dominated.
Dry conditions remain in place Tuesday although reduced fire danger is expected in advance of an arctic air mass shifting south bringing much cooler and cloudy conditions as well as some precipitation chances Tuesday night and Wednesday.  The opportunity for elevated fire danger may develop in western Oklahoma on Friday ahead of another frontal boundary.
Burn Ban Status:   No Burn Bans presently in effect.
