Statewide Discussion: 

No significant fire danger anticipated today with light precipitation this morning in many areas and increasing potential as the day wears on.  Saturday does pose to present a brief period of notable fire danger potential with the most concerning indices in southwest Oklahoma.  In short, there are several limiting factors affecting fuel receptiveness; however any wildfire that does become established will very likely present significant suppression challenges during the afternoon and early evening hours.  Rain chances do increase through the day today and into the evening although amounts of less than 0.10” inch are expected in southwest Oklahoma where the driest fuels are present.   Wind and drier air will facilitate rapid drying of fine-dead fuels especially in areas where amounts less than 0.2” are received.  Likewise, any location where precipitation amounts are heavier will experience much less opportunity for fire danger development.
Saturday will likely see fire danger develop south and west of a line from Roger Mills to Jefferson Counties (Roger Mills, Beckham, Greer, Kiowa, Harmon, Jackson, Comanche, Tillman, Cotton and Jefferson Counties).  Areas to the north and west of this line will experieince limited fire danger potential.  In the area described above, temperatures are expected to approach 60° with relative humidity values falling into the 28-35% range.  Fine-dead fuel moisture values may dip to 6% although the potential for blowing dust poses opportunity for fuel shading limiting overall fuel dryness.  Expect erratic, scudding fire behavior as winds transition from the south to west sustained around 35 mph with gusts in excess of 50 mph.  Worst case scenario fire behavior below:
Grazed/hayed grasses have potential to hit the wind limit exhibiting 297 ft./min. with 7-8 flame lengths.
Uniform, native grasses, 405-520 ft./min (4.5-5.9mph) with flame lengths around 20 ft. at the head fire.
Sunday will bring drier air across Oklahoma with relative humidity values ranging from the low-20%’s in southwest Oklahoma to 40% northeast and temperatures generally in the 50°’s.  Fuels will become increasingly receptive during the afternoon hours although winds will be much less of a factor providing for very good initial attack success probability.
Special Note to Firefighters:  Fire behavior potential on Saturday afternoon will present challenges should any fire become established. Firefighters are encouraged to “Take a minute to make a plan, rather than making a plan a minute”.
Anchor the fire at an advantageous barrier to fire spread (road, wheat field, creek, etc.) and flank the fire from the black progressing toward the head utilizing direct, attack-from-the-black methods incorporating barriers to fire spread when possible including wheat fields, barren land or man-made features.  Indirect tactics where unburned fuel is present between you and the fire are likely to be unsuccessful posing high risk to firefighters.  If engaged in structure protection tactics, insure that your apparatus is backed in, escape routes to safety zones are identified, and trigger points for utilizing escape routes are in place.
Burn Ban Status:   No Burn Bans presently in effect.
