Statewide Discussion: 

Red Flag Warning in effect from Noon until 9:00 PM today for Cimarron and Texas Counties.

Wetting rains occurred Friday night through Saturday across a good portion of Oklahoma generally south and east of a line from Harmon County to Nowata County. This will support vigorous green-up in herbaceous fuels and leaf-out in timber fuels providing a reduction in fire behavior potential as well as downgraded resistance to control in those areas where rainfall amounts between 0.3”-2.0”+ were received. On the other hand, the Oklahoma Panhandle, northwest and north-central counties received little to no rainfall where green-up has stalled. Elevated fire weather is expected through mid-week in these areas and will support active fire behavior in rangeland fuels although resistance to control should top out only in the moderate range.

The highest fire danger indices today will span the Panhandle into northwest Oklahoma primarily northwest of a line from Roger Mills County to Alfalfa County. In this area, temperature will push into the mid- to upper-80º’s under clear to partly cloudy skies with afternoon relative humidity values as low as 9% in Cimarron County to 25% on the eastern edge of the dry line. Dormant grasses will be available with fine-dead fuel moisture values 3-4% across this area (a 2% observation is possible late this afternoon in the western Panhandle). Winds will gradually increase through the day with southwest winds 15-20 mph and some gusts near 30 mph supporting rapid rates of fire spread in dormant fuels on the order of 138-249 ft./min. with head fire flame lengths 12-16 ft.

Warm temperatures, relative humidity values 25-40% and southerly winds 15-20 mph with higher gusts will facilitate some potential for initial attack activity elsewhere generally confined to the drier timber sites and areas where decadent warm-season grasses with heavy thatch loading dominate. Given ample barriers to fire spread and improving live fuel moisture values, resistance to control is expected to be minimal.

A series of dry line intrusions ahead of a more significant system on Wednesday will hold fire danger in place each afternoon across portions of western Oklahoma. Focus will primarily be on the northwest and Panhandle counties where fuels are direst and separation from wetting rains is in excess of 20 days. Post-frontal conditions on Thursday have potential to support increased fire danger as well although dependent upon spatial coverage, duration and amount of rainfall.

Burn Ban Status: No Burn Bans presently in effect.
