...CRITICAL FIRE WEATHER AREA FOR PARTS OF SOUTHERN IDAHO...FAR
NORTHEAST NEVADA...AND FAR SOUTHEAST OREGON...

The previous forecast (see below) remains on track, and only minor
changes were made based on the latest observations and
high-resolution guidance. In particular, the Critical area was
expanded slightly southward and westward into far northeastern NV
and southeastern OR. Here, around 20 mph sustained
west-northwesterly surface winds and 5-10 percent RH will support
locally critical conditions, given increasingly dry fuels over the
area.

...Synopsis...
A broad mid-level trough is expected to be situated over the central
CONUS, with a shortwave trough and associated speed max traversing
the northwestern CONUS through the day today. The surface response
to this shortwave trough should produce breezy conditions across
parts of the Pacific Northwest and Great Basin (wind gusts generally
30-35 mph) overlapping strong mixing and low RH values (generally
5-15% RH). Fuels in the region are somewhat receptive, particularly
in the Snake River valley in Idaho, where a Critical area has been
maintained. Some Critical conditions are possible across parts of
southeast Oregon and southwest Wyoming. However fuels in this region
are less receptive, and therefore have not expanded the Critical are
to these regions.

In addition, some transient Elevated to Critical conditions are
possible in the southern California coastal range and Transverse
Ranges. However, despite low RH and generally receptive fuels, any
gusty winds will be localized and transient. Therefore, no Elevated
highlights have been included in this region.
