Statewide Discussion: 

Rainfall associated with storms on the leading edge of the cold front passing yesterday evening and overnight will quell fire danger concerns today across most of the eastern half of Oklahoma today. Areas generally west of I-35 remained dry with fire danger remaining elevated. The post-frontal fire environment in western Oklahoma will hold increased fire danger concerns in place through mid-week ahead of the next weather system bringing much cooler temperatures and precipitation chances.

Western OK / OK Panhandle: Cooler temperatures today – mid-60’s in the Panhandle to 65-73⁰ in western counties following a much cooler start. Low dewpoint temperature will yield afternoon relative humidity values 12-18% in the western 1/3rd of Oklahoma and 18-27% nearing I-35. Fine-dead fuel moisture values of 4-5% are expected during peak burning conditions with clear skies. West-northwest winds this morning are expected to be northwest this afternoon increasing to 12-20 mph with some gusts in excess of 20 mph. Rates of spread in rangeland fuels will have potential to produce head fire rates of spread 155-215 ft./min. with flame lengths 11-13 ft.. Poor overnight moisture recovery will promote early development of the burning period. While initial attack efforts are expected to be successful, it is worth noting that Energy Release Component (ERC-G) values are increasing with several western Oklahoma locations eclipsing 75th percentile rankings. Firefighters should be mindful of increasing resistance to perimeter control efforts as fuel dryness and availability both increase.

I-35 to Hwy. 183: Afternoon relative humidity values 16-25% will support increased fine fuel availability with afternoon fine-dead fuel moisture values 5-6% as temperatures warm into the upper-60’s. Northwest winds 10-18 mph with gusts in the northern counties near 25 mph will facilitate rates of fire spread in rangeland fuels 135-185 ft./min with flame lengths around 11 ft. Grass/Brush fuels will support rates of spread 45-70 ft./min. with flame lengths averaging 8-12 ft. Expect single and group tree torching in juniper pockets although spotting potential in moderate and should be very short-range.

Dry conditions west of I-35 will hold moderate to very-high fire danger indices in place through at least the middle of the week. Reduced wind speeds will lessen the potential rate of fire spread Tuesday although fuels across the western half of the state will remain quite receptive. Increased fire danger indices are expected again on Wednesday ahead of another cold front passing bringing an opportunity for rainfall.
