...CRITICAL FIRE WEATHER AREA FOR SOUTHWEST INTO CENTRAL NEVADA...

...Synopsis...
A mid-level impulse embedded in the broader cyclonic flow aloft will
traverse the West Coast and impinge on the Pacific Northwest while
an upper ridge persists across the central U.S. today. The departure
of upper support will result in somewhat weaker isallobaric flow
from the lee of the Cascades into the Great Basin co*pared to
yesterday. Nonetheless, some residual gradient flow, co*bined with
robust boundary layer mixing, will support dry and windy conditions
during the afternoon to the lee of the Sierra into the western Great
Basin, where Elevated highlights have been maintained. Critical
highlights remain where guidance consensus shows the greatest chance
of 20+ mph sustained southwesterly surface winds overlapping with 15
percent RH and fuels receptive to wildfire spread.
