Statewide Discussion:

Increased fire danger today with above normal temperatures serving to drive relative humidity values into the teens and 20’s this afternoon and fine-dead fuel moisture into critical values. Winds will switch from southwest to northerly as a boundary transitions across Oklahoma today and with the switch will come an increase in intensity and gusts facilitating rapid rates of fire spread. Similar to yesterday, the highest fire danger indices will be present in both southeast and northwest and far western Oklahoma along with high fire danger indices statewide.

Southeast Oklahoma: Temperatures nearing 70°, relative humidity values dropping into the 20-24% range, southwest to west winds 10-15 mph gusting near 20 mph and strong ventilation rates will promote aggressive fire behavior today. Large fuels are critically dry and will burn intensely. Anticipate surface fire transitioning into canopy fuels in pine dominated fuel types with group torching, short crown runs and short-range spotting.

Panhandle/Northwest/Western Oklahoma: Given the poor overnight moisture recovery, expect the burning period to develop quickly today and vigorously as winds increase. Relative humidity values this afternoon in the 16-20% range translate into fine-dead fuel moisture values of 5% widespread across the area as temperatures warm in to the low to mid-60°’s. Winds shifting from the west to north by afternoon will intensify to 17-22 mph gusting near 30 mph at times. Rates of fire spread of 150–225 ft./min. and problematic fire behavior on the east flanks in grass fuels prominent in the region.

Despite the shorter days and lower sun angle of the season, expect a longer than normal burning period today with fine fuel moisture prompting very receptive fuels before noon through the evening hours. Fine dead fuel moisture values will settle into the 5-6% range statewide today with clear skies and above normal temperatures. The wind shift from west to north will impact counties along the I-35 corridor midday and eastern Oklahoma early evening. Rapid rates of fire spread are likely today; however initial attack is expected to be successful in central and much of eastern Oklahoma.

Dry conditions will be persistent; however fire danger on Thursday and Friday will be lower grade with somewhat cooler temperatures and lighter winds. Another approaching cold front will spike fire danger on Saturday ahead of some unimpressive rain chances.
