Statewide Discussion: 

Another hot day today ahead of a cold front that holds some promise of precipitation this morning in parts of the Oklahoma Panhandle and into northwestern Oklahoma into the evening. The current forecast does hold some opportunity for rainfall in the dry southwestern counties where drought observations have intensified although there is little optimism for wetting amounts. Cooler temperatures are anticipated across much of Oklahoma with the passage of the cold front although the southern counties, especially those along the Red River, will see little relief. Given the current short-term forecast and current fire environment assessment, the probability of significant fire occurrence is low and initial attack activity should continue to prove successful.

Today: Temperatures this afternoon are again expected to top 100⁰ in across most of Oklahoma with persistent fire danger focused in the southwestern counties and along the tier into southeast Oklahoma. 

  • Southwest - Somewhat lower dew point temperatures will facilitate afternoon relative humidity values dropping below 25% in much of the southwestern quarter of Oklahoma facilitating receptive fine-fuels during the afternoon and early evening hours. Southerly winds generally around 10 mph with gusts less than 20 mph will serve to hold potential rates of spread in check with grass-dominated fuels averaging 70-80 ft./min. and head fire flame lengths around 8-9 ft. 
  • Northwest/OK Panhandle – Rainfall this morning across parts of the Panhandle will serve to dampen fire danger today although northwestern counties will see temperature tap 100⁰ in the pre-frontal environment. Afternoon relative humidity values around 30%, seasonal live-fuel moisture and generally light winds will yield only moderate fire behavior expectations. Lightning activity level will increase along with storm chances this evening and should be considered as a source of potential fire starts especially on the periphery of wetting storms. 
  • Southeast – Pine-dominated and pine plantation fuels (especially the higher sites) with drying days. Rates of fire spread 15-25 ft./min. with 4-7 ft. flame lengths should be expected with surface fire although problematic fire behavior including single-tree and group-tree torching should be expected in addition to short crown runs in un-thinned stands.

Tuesday: Temperatures in the upper 90⁰’s to 102⁰ remain in the southern tier of counties while cooler, post-frontal temperatures in the low-90⁰’s are expected in the northern 2/3rd’s of Oklahoma. Higher afternoon relative humidity and light north to northeast winds will serve to moderate fire behavior potential supporting very good probability of successful initial attack efforts.

Rain chances migrate across the state into mid-week with the best opportunity for wetting rains resides in northern Oklahoma. Little mitigation to the building dryness that extend from southwestern Oklahoma into parts of central Oklahoma including much of Cleveland County is expected although the absence of critical fire weather contributors will serve to limit fire behavior on new ignitions.

Burn Ban Status: No Burn Bans presently in effect
