...SYNOPSIS...
A MID-LEVEL TROUGH WILL APPROACH THE PACIFIC NORTHWEST
COAST...RESULTING IN STRENGTHENING SOUTHWESTERLY FLOW ACROSS MUCH OF
THE REGION. DOWNSTREAM...THE SYNOPTIC PATTERN ALOFT WILL FEATURE
LITTLE CHANGE...AS AN EXPANSIVE CYCLONE REMAINS CENTERED OVER
KY...AND RIDGING PERSISTS OVER THE PLAINS STATES.

...PORTIONS OF THE FAR NORTHWEST GREAT BASIN...
DUE TO THE AFOREMENTIONED STRENGTHENING FLOW ALOFT...BREEZY
CONDITIONS WILL BE EXPERIENCED IN THE LEE OF THE NORTHERN
SIERRA/SOUTHERN CASCADES TODAY. SUSTAINED WINDS AROUND 15-20 MPH
SHOULD MATERIALIZE BY MID-DAY. MOREOVER...THE COMBINATION OF
DOWNSLOPE FLOW AND AN ANTECEDENT DRY AIR MASS WILL ENCOURAGE MIN RH
VALUES AROUND 15-20 PERCENT. WITH AREAS OF DRY FUELS PRESENT...THESE
METEOROLOGICAL CONDITIONS WILL SUPPORT ELEVATED FIRE-WEATHER
CONCERNS.
