   ...CRITICAL FIRE WEATHER AREA FOR PARTS OF SOUTHERN
   NEVADA...SOUTHWESTERN UTAH...AND FAR NORTHWESTERN ARIZONA...

   ...Southern Nevada, Southwestern Utah and far Northwestern
   Arizona...
   Modest mid-level flow associated with a progressive upper-level
   trough will move into the Great Basin and Southwest Monday. A very
   dry, well-mixed boundary layer will support low teens to single
   digit relative humidity values across the region. A corridor of
   20-30 mph winds are most likely from southern Nevada into
   south-central Utah where very low daytime humidity will support
   Critical fire weather conditions amid dry fuels.

   ...Columbia Basin...
   The upper-level short wave translating through the Pacific Northwest
   Monday will contribute to enhanced downslope winds particularly
   across the western portions of the Columbia Basin. West winds of
   around 15 mph combined with relative humidity in the 15-25 percent
   range will result in elevated fire weather concerns for central
   Washington state and Columbia River Gorge where ongoing fire
   activity remains.

   .PREV DISCUSSION... /ISSUED 0156 AM CDT Sun Jun 15 2025/

   ...Synopsis...
   During the day on Monday, a mid-level shortwave trough is expected
   to traverse California and into the Great Basin, and the surface
   mass response to this feature will tighten the sea-level pressure
   gradient across the area, resulting in strong surface winds. With
   seasonably strong vertical mixing, RH in the Great Basin and Four
   Corners region is expected to be around 5-15%. The best overlap of
   windy conditions and dry fuels is expected to be across parts of
   southeast Nevada, southwest Utah, and far northwest Arizona, where
   Critical highlights have been added. In this area, winds are
   expected to be near 20-30 mph with gusts as high as 35-40 mph
   underneath the core of the mid-level jet associated with the
   shortwave trough. Surrounding that Critical area, winds may be
   weaker and fuels less receptive to fire spread. However, this still
   warrants an Elevated area across parts of the Great Basin and Four
   Corners region.

   Valid 171200Z - 231200Z

   ...Day 3-4/Tuesday-Wednesday...
   An eastward propagating upper-level short wave trough and associated
   increased mid-level flow will overspread the Southwest on Day
   3/Tuesday. Critical probabilities were maintained as prolonged burn
   periods with poor to moderate RH recoveries and single digit daytime
   RH values combine with southwest winds of 15-25 mph across eastern
   Arizona and western New Mexico. A 40 percent probability area was
   added for the Columbia Basin for Day 4/Tuesday as another Pacific
   Northwest short wave trough moves into the region supporting
   downslope/leeward drying and breezy west winds across the area amid
   dry fuels.

   ...Day 5-8/Thursday-Sunday...
   A deepening upper-level trough begins to impact the western U.S. on
   Day 5/Thursday, promoting a multi-day fire weather threat across the
   Great Basin with fire weather concerns shifting east into the
   Southwest and Intermountain West into the weekend. Fuels will
   continue to dry across the region under an above normal temperature
   regime with dry, breezy southwest winds setting the stage for
   increased fire spread potential. Dry and breezy conditions could
   also impact ongoing active fires across the region.
