Statewide Discussion: 

Wetting rainfall across much of the northern half of Oklahoma and persistent chances across much of the state through the day will facilitate reduced fire danger today. Southwestern and areas of south-central Oklahoma are not expected to receive wetting amounts - if any - rainfall. Increasing separation from wetting rains, continued hot temperatures and persistent dry conditions are prompting the shift to increasing fine-fuel availability as drought indicators emerge in southwestern Oklahoma. No critical fire weather is in the near-term forecast through the weekend, although few pockets of elevated fire danger potential are expected early next week.

 Today: Fire danger today will be limited by rainfall across areas of Oklahoma. The dry southwestern and south-central counties may see a smattering of rain, but rather light winds with improved atmospheric moisture hampering fire behavior.  

Saturday: The highest fire danger indices will be reside in southwestern Oklahoma where temperatures 99⁰-105⁰ and afternoon relative humidity values 22-28% will translate into receptive fin fuels during the afternoon hours. South winds 5-10 mph will serve to limit rates of fire spread should any new fires start. Rates of fire spread in grass-dominated fuels of 25-50 ft./min. with head fire flame lengths averaging 5 ft. should be expected providing good probability of successful initial attack.

Sunday: Again, the highest fire danger indices are expected in southwest Oklahoma. During peak burning conditions in the afternoon hours, temperatures 100⁰-106⁰ combined with relative humidity values 21-27% will yield fine-dead fuel moisture values tapping 4%. Very dry dead fuels and declining live-fuel moisture will translate into increased receptiveness. South-southwest winds 8-12 mph with some gusts near 20 mph will support rates of fire spread in grass dominated fuels 65-100 ft./min with head fire flame lengths averaging 6-10 ft. Firefighters should expect some problematic fire behavior including single-tree torching and potential for spot fires. 

Hot and dry conditions into early next week across southwestern Oklahoma will result in persistent fire danger. Overall, initial attack efforts are expected to be successful in the coming days without alignment of critical fire weather elements. Nonetheless, a slight uptick in initial attack activity is expected. Firefighters are strongly encouraged to maintain adequate hydration well in advance of a fire dispatch.

Burn Ban Status: No Burn Bans presently in effect
