...A PARTICULARLY DANGEROUS SITUATION FOR THE FOOTHILLS OF AND IMMEDIATELY ADJACENT OF THE SOUTHERN LARAMIE RANGE THROUGH LARAMIE COUNTY IS EXPECTED ON FRIDAY... A strong wind event is ongoing and expected to continue to strengthen through much of today alongside rising temperatures and dry conditions including humidity values into the teens. With sustained winds of 40 to 55 mph and gusts of 60 to 75+ mph expected alongside these dry conditions, an extreme environment conducive of significant and rapid wildfire spread will be present. The most likely time for stronger winds and lowered relative humidity values will lie just after sunrise through the late afternoon and early evening hours, with the potential for lowered relative humidity values lingering beyond sunset due to the expected dry flow across the region. This environment will be most likely for elevations below 8000 feet along the southern Laramie Range and eastwards through most of Laramie County. * AFFECTED AREA...Fire weather zones 417, 418, 432, 433, 434, 435, 436, and 437. * WIND...Sustained winds 30 to 50 mph. Gusts in excess of 55 to 70 mph. * HUMIDITY...RH values 15 to 30%. * IMPACTS...Any fires that develop will likely spread rapidly. Outdoor burning is not recommended. Although conditions will be borderline in some zones, a lack of significant precipitation combined with the very high winds in the region will create a critical fire weather environment.
