...CRITICAL FIRE WEATHER AREA FOR PARTS OF SOUTHERN NEVADA INTO
SOUTHWESTERN UTAH...
Critical fire weather conditions appear more likely just ahead of a
southeastward moving surface boundary. Parts of southern Nevada and
southwestern Utah have greater potential for a few hours of
sustained 20+ mph winds. Elsewhere, elevated to locally critical
conditions are still expected across a broad area of the Great Basin
and Southwest. See the previous discussion for details.

...Synopsis...
Increasing west to southwest winds across parts of the southern
Great Basin, Southwest, and Four Corners will lead to a broad swath
of fire weather concerns Friday afternoon. The upper-level wave
currently approaching the Pacific Northwest is forecast to translate
into the northern Rockies by late Friday. Falling heights aloft will
support modest surface pressure falls over the inter-mountain West,
resulting in a broad low-level mass response from the southern Great
Basin into the Four Corners and Southwest. Ensemble guidance and
deterministic solutions generally suggest that 15-20 mph winds will
be co*mon across this region. Drier/windier solutions indicate that
areas of 20-25 mph winds are possible, but considerable spread in
deterministic solutions introduces uncertainty regarding the exact
placement and coverage of the strongest winds. Strong mid and
upper-level winds will largely be displaced to the north of the
region, which further limits confidence on where the windiest
corridors will be established within the risk area.
Nonetheless, dry conditions will prevail with 10-15% RH values
expected by late afternoon. Widespread elevated conditions are
likely, and a few corridors of critical conditions are possible.
Similar wind/RH conditions are possible across much of the southern
High Plains as well, but widespread rainfall over the past few days
has mitigated fuel status for the time being. Fuel trends will be
monitored for a possible expansion, but Friday's warm/dry conditions
will likely begin the drying process for most locations as
temperatures rebound into the 90s.
