...NO CRITICAL AREAS...
...SYNOPSIS...
AN UPPER TROUGH WILL MOVE SEWD ACROSS THE NRN AND CNTRL ROCKIES WITH
A SURFACE COLD FRONT DRAPED SW ACROSS THE GREAT BASIN. COOLER AIR
WILL EXIST BEHIND THIS FRONT BUT GUSTY WINDS AND LOW RH WILL CREATE
A MARGINAL FIRE WEATHER THREAT FROM NRN CA INTO SRN ID. AN OFFSHORE
PRESSURE GRADIENT WILL ALSO CREATE GUSTY WINDS FOR WRN OREGON.
TO THE E...AN AREA OF LOW PRESSURE WILL DEEPEN FROM SD INTO ERN CO
AHEAD OF THE APPROACHING UPPER TROUGH. STRONG WINDS WILL DEVELOP OUT
OF THE SOUTH OVER THE PLAINS STATES AS A RESULT...BUT RH WILL REMAIN
HIGH. FARTHER E...AN EXPANSIVE SURFACE HIGH WILL EXTEND FROM THE MS
VALLEY INTO NEW ENGLAND...WITH COOLER AND DRY WEATHER.
...SRN ID...NRN NV...NERN CA...
NWLY WINDS OF 15-20 MPH ARE LIKELY IN A POST FRONTAL REGIME THIS
AFTERNOON. DESPITE COOLER TEMPERATURES...MIN RH WILL STILL DROP INTO
THE 10-15 PERCENT RANGE. THE STRONGEST WIND GUSTS WILL BE OVER SRN
ID WITH SPEEDS OF 20-30 MPH POSSIBLE.
GUSTY N WINDS ARE ALSO LIKELY ACROSS NRN CA...DUE TO DOWNSLOPE WINDS
FROM HIGH PRESSURE TO THE N. RH RECOVERY WILL BE MINIMAL WHERE WINDS
PERSIST.
...WRN OREGON...
GUSTY NLY WINDS OF 10-20 MPH WILL OCCUR DURING THE DAYTIME WITH MIN
RH DROPPING INTO THE 20 PERCENT RANGE. GUSTY WINDS AND POOR RH
RECOVERY WILL RESULT OVERNIGHT DUE TO A LOW PRESSURE TROUGH THAT
WILL LIE ALONG THE COAST...AND AS AIR FLOWS DOWNSLOPE OUT OF HIGH
PRESSURE TO THE E.
