DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1056 AM CDT FRI OCT 24 2014

VALID 251200Z - 261200Z

ADDED AN ELEVATED RISK AREA THIS UPDATE ACROSS PARTS OF NWRN NV AND
FAR E-CNTRL CA.

...NWRN NV...FAR E-CNTRL CA...
A STRONG MIDLEVEL SPEED MAX ACCOMPANYING AN APPROACHING PACIFIC
UPPER TROUGH WILL OVERSPREAD THE WRN GREAT BASIN DURING PEAK
HEATING. THE COMBINATION OF AMPLE BOUNDARY-LAYER MIXING AND A
TIGHTENING SFC PRESSURE GRADIENT IN RESPONSE TO PRESSURE FALLS OVER
THE INTER-MOUNTAIN WEST AND AHEAD OF A PACIFIC COLD FRONT WILL
SUPPORT SUSTAINED WIND SPEEDS OF 20-30 MPH AND GUSTS OF 40-50 MPH.
PRIMARY FACTOR LIMITING A CRITICAL RISK AREA WILL BE MARGINALLY LOW
RH VALUES...WHICH ARE GENERALLY FORECAST TO RANGE BETWEEN 15-20
PERCENT DURING THE AFTERNOON. LONG-TERM DROUGHT ACROSS THE AREA IN
COMBINATION WITH THE STRONG WINDS WILL BE SUPPORTIVE FOR AN ELEVATED
RISK AREA...WITH PERHAPS SPOTTY/BRIEF CRITICAL CONDITIONS OCCURRING
IN LOCATIONS WITH SUFFICIENTLY LOW RH.

...SYNOPSIS...
AN UPPER-LEVEL RIDGE WILL WEAKEN AS IT MOVES EWD ACROSS THE CENTRAL
CONUS ON SATURDAY WHILE A TROUGH MOVES ONTO THE WEST COAST.  AT THE
SURFACE...A LOW-PRESSURE SYSTEM WILL MOVE INTO THE PACIFIC NORTHWEST
AND DEVELOP EWD TOWARD THE NRN ROCKIES WHILE A SOUTHWARD-EXTENDING
COLD FRONT ADVANCES EWD ACROSS THE GREAT BASIN.  WINDY CONDITIONS
/SUSTAINED SURFACE WINDS AOA 20 MPH/ WILL PRECEDE AND FOLLOW FRONTAL
PASSAGE ACROSS MOST OF THE CENTRAL GREAT BASIN...HOWEVER...THE
LATEST MODEL SOLUTIONS ARE TOO MARGINAL/MOIST ACROSS THIS REGION TO
WARRANT HIGHLIGHTING FIRE-WEATHER CONCERNS AT THIS TIME.
