Statewide Discussion: 

Dry conditions yesterday facilitated substantial drying of fine-dead fuels following rains Friday evening into Saturday. Cool morning temperatures, some morning sprinkles west and sky cover clearing from west to east through the day will stall development of concerning fire danger today confining active burning conditions to a few hours this afternoon. Dry conditions anticipated on Tuesday with increasing fire danger into the afternoon hours although no significant fire occurrence expected. Attention turns to Wednesday when a dry line forecasted to push to the OK/TX state line merits watching with reference to both increased fire danger and severe storm potential.

Today: Cool morning temperatures, morning sky cover and light precipitation overnight in the Panhandle and some sprinkles west will stall development of fire danger today. Skies will likely clear from west to east through the day with temperatures across the state this afternoon 53°-61° and afternoon relative humidity values 25-35%. Dormant, fine fuels will be receptive, but rates of spread are expected to be moderated with southerly winds generally less than 10 mph.

Warmer temperatures on Tuesday combined with receptive dormant, fine fuels and slightly increased south winds will produce moderate rates of fire spread. Temperatures in the upper-60°’s to low-70°’s and relative humidity values again 25-35% across most of the state will yield fine-dead fuel moisture values of 5-6% during the peak of the burning period. Homogenous, tall grass fuels will support rates of spread in the 150-190 ft./min. range with flame lengths 10-14 ft. given sustained south winds 10-15 mph. Afternoon winds in southwest Oklahoma are expected to be somewhat stronger yielding increased rates of fire spread where wind and fuels are aligned with topography. Presently, fuels are not exhibiting much in the way of resistance to suppression facilitating continued expectation of successful initial attack activity.

Wednesday merits some mindfulness regarding fire danger for two reasons: 1) A dry line is expected to establish in the vicinity of the OK/TX border. Should the dry line shift east, elevated fire danger concerns will be present along the western tier of counties where the driest conditions overall are present. And, 2) Pre-frontal dryness combined with stronger/more gusty winds will drive potential for very rapid rates of fire spread in parts of central, north-central and northeastern Oklahoma.

Special Note to Firefighters:

A recurrent theme in 2019!… Saturated soils will render numerous challenges and safety concerns when firefighters are engaged in mobile engine attack. Firefighters are encouraged to scout access prior to committing engines on the fireline, attack from the black to insure that vehicles do not become stuck in unburned fuels and anchor fires at the heel progressing on the flanks toward the head. If values at risk are threatened, consider establishing point protection tactics insuring egress and escape routes to safety zones are established.

To facilitate a quick and meaningful training discussion, firefighters can refer to the Oklahoma Wildland Tailgate series, Engine Tactics or Urban Interface editions at http://www.forestry.ok.gov/tailgate

Burn Ban Status: No Burn Bans presently in effect.
