...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SOUTHERN
UTAH...NORTHERN ARIZONA...WESTERN NEW MEXICO...AND FAR SOUTHWEST
COLORADO...

...Update...
The previous forecast remains valid. Very minor adjustments were
made to the Critical area near the CO/UT border, with a slight
extension northeastward into CO. Sustained wind speeds near 25-35
mph will be possible there, with RH dropping into the single digits
later this afternoon. In addition, the Elevated area was extended
across southern CO to include the Sun Luis Valley, and eastward into
the far western OK and TX Panhandles. The Guadalupe Mountains were
also included in the Elevated area. All of the aforementioned
regions should experience elevated to critical meteorological fire
spread conditions for at least a couple of hours today. Please see
the discussion below for more details.

.PREV DISCUSSION... /ISSUED 0157 AM CDT Mon Jun 17 2024/

...Synopsis...
A shortwave will rotate through the western US trough today,
bringing strong southwesterly flow across much of the desert
southwest into the southern High Plains. Across northern Arizona,
southeastern Utah, and portions of western New Mexico, Critical fire
weather is expected where afternoon relative humidity reductions to
10-15 percent will overlap sustained winds around 20 mph and
critically dry fuels. Broader Elevated fire weather concerns are
expected across much of Arizona into southern/central Utah, eastern
Nevada, and into western New Mexico and southern Colorado.

Elevated fire weather concerns are also expected within the
Sacramento Valley, San Joaquin Valley, the western Transverse
Ranges, and the southern Sierra Nevada in northern/central
California where strong northwesterly flow at 10-15 mph (locally
stronger in foothills and mountain passes) will overlap relative
humidity reductions to 15-20 percent (locally around 10 percent)
Fuels within much of this region are sufficiently dry to support
Elevated fire weather concerns and recent fire activity suggest that
fuels are drying quickly and supportive of fire spread.
