Statewide Discussion: High to Extreme fire danger will develop today across Oklahoma ahead of an approaching cold front.  Critical to near critical fire weather will be present early in the day as overnight moisture recovery was rather poor prompting issuance of a Red Flag Warning for all of central and western Oklahoma spanning forty-eight counties.  The cold front is expected to pass in the overnight hours with a pronounced and rapid shift of winds from the southwest clockwise to the north.

 

Western Oklahoma – Temperatures near 55°-60° under mostly clear skies.  Relative humidity values are expected to drop into the 15-25% range.  Fine dead fuel moisture of 5% is expected early in the burning period coupled with winds south to southwest 20-30 mph with gusts around 40 mph.  Rates of fire spread will have potential to be extreme at 320-375 ft./min in typical grass fuels and around 200-225 ft./min. in grass/shrub fuels.  Note**  A surge of atmospheric moisture ahead of the front may prompt somewhat higher relative humidity values this afternoon; however winds will likely increase along with this. The cold front is expected to enter western Oklahoma a little before midnight prompting a rapid clockwise wind shift from southwest to northerly winds.

 

Central Oklahoma – Temperature 55°-60° under clear skies.  Relative humidity values mainly 15-20% this afternoon with some locations likely falling to near 10% promoting fine dead fuel moisture of widespread 5% and as low 4% locally.  Winds will be somewhat lighter than in western Oklahoma, but 10-20 mph winds with gusts expected in excess of 20 mph will translate into rapid rates of fire spread.  Grass fuels will exhibit 250-300 ft./min. with timber fuels moving around 30-70 ft./min. along with flamelengths in excess of 6 ft. on the head fire. Cold front passage will occur in the overnight with the wind shift from southerly to northerly occurring in a rapid manner.

 

Eastern Oklahoma – Temperatures near 60° with relative humidity values 15-25%.  Winds 10-15 mph with gusts as high as 25 mph.  Again, rapid rates of fire spread are expected along with potential for short-range spotting up to 200 yds.. Timber fuels will likely exhibit rates of spread of around 20-60 ft./min. with flamelngths around 4-8 ft.  Expect fire behavior to exceed predictions when wind and topography are aligned.  Cold front passage is expected in the early morning hours.

 

Special Note to Firefighters:

• Expect fires to be resistant to control efforts given the low relative humidity and drought intensification driving large fuel moistures very low.

• County Wildland Task Force Resources should be prepared for mobilization today.

• Helicopter requests can be made through the Resource Hotline (800) 800-2481.
