Statewide Discussion: 

The highest fire danger today will reside in the Panhandle while more moist conditions progressing toward the east through Oklahoma will hold fire danger at bay in large part today. More widespread fire danger is expected on Thursday with gusty northwest winds in the forecast and dry air over dormant fuels.

In the Oklahoma Panhandle, temperatures will warm into the upper 50°’s to low 60°’s following a cool start to the day. Fine-dead fuel moisture values will fall into the 5-6% range with relative humidity values at most sites 20-25%. Lingering sky cover may aid in holding fine fuel moisture from dipping lower although should skies become clear expect some areas to see potential for extremely receptive fuels. West-northwest winds this morning will become northerly this afternoon at 20-25 mph with gusts 30-35 during the peak of the burning period. Of note, Energy Release Component (ERC-G) has eclipsed the 60th percentile (approaching 70th percentile in some locations) translating into increasing resistance to suppression efforts. In grass dominated fuels typical of the area, expect head fire rates of spread of 260-320 ft./min. with 8-12 ft. flame lengths on free burning, established fires. Brush dominated fuels will exhibit comparatively moderated rates of spread although expect increased intensity where fuels are aligned with wind and topography.

On Thursday, fire danger concerns will expand into the western half Oklahoma along with potential for increasing concern in parts of central and eastern Oklahoma. Fire weather is not expected to meet critical criteria although parched, dormant fuels will support rapid rates of fire spread in the western counties. The chance for precipitation in areas of the state today will have to be factored in to demining the eastern extent of the potential for tomorrow.
