...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SOUTHERN OREGON INTO
EXTREME NORTHERN CALIFORNIA...

...Synopsis...
Upper ridging will remain in place across the western U.S. today
while a mid-level trough ejects into the Plains states during the
afternoon. Downslope flow along the higher terrain in western
Montana and modest surface lee troughing across the northern Plains
may support at least locally dry and windy conditions for a few
hours.

The bigger concern for wildfire-spread potential today exists across
the Pacific Northwest. Modest deep-layer ascent with passing subtle
mid-level impulses will work in tandem with afternoon peak heating
to support the initiation of scattered high-based thunderstorms
across portions of the Pacific Northwest, where fuels have recently
beco*e highly receptive to fire spread (based on the latest
observations). The previous day's storms may have slightly dampened
fuels locally. However, the relatively higher number of thunderstorm
expected today, co*bined with the critically dry fuels (especially
in lower-terrain areas) necessitates the addition of scattered dry
thunderstorm highlights.
