NWS STORM PREDICTION CENTER NORMAN OK
0115 AM CST FRI JAN 09 2009
VALID 091200Z - 101200Z
...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE SRN CA COASTAL
AREA...
...SYNOPSIS...
A POSITIVELY-TILTED SHORT WAVE TROUGH EXTENDING FROM THE NRN ROCKIES
TO THE GREAT BASIN SHOULD STRETCH FROM THE CNTRL PLAINS TO THE SRN
ROCKIES BY EARLY SAT. A SURFACE COLD FRONT WILL SWEEP SEWD INTO THE
SRN PLAINS THIS AFTERNOON. STOUT SURFACE HIGH PRESSURE WILL BUILD
INTO THE GREAT BASIN WITH A TIGHT PRESSURE GRADIENT LYING ACROSS SRN
CA.
...CRITICAL FIRE WEATHER AREA - PORTIONS OF THE SRN CA COASTAL
AREA...
PRIMARY CONDITIONS: STRONG OFFSHORE WINDS / LOW RH / MODERATE
DROUGHT
OFFSHORE FLOW WILL STRENGTHEN THIS MORNING RESULTING IN PERIODS OF
SUSTAINED WINDS FROM 20 TO 30 MPH WITH GUSTS AOA 50 MPH ALONG THE
COASTAL MTNS AND ADJACENT CANYONS/PASSES. DOWNSLOPE WARMING/DRYING
WILL RESULT IN RAPIDLY LOWERING RH WITH VALUES FALLING TO AOB 15
PERCENT BY MID AFTERNOON...AND LITTLE IF ANY RH RECOVERY OVERNIGHT.
ALTHOUGH THESE CONDITIONS SHOULD EXTEND ALONG MUCH OF THE SRN CA
COASTAL AREA...ANTECEDENT HIGH FUEL MOISTURES SHOULD CURTAIL THE
OVERALL THREAT S OF THE LOS ANGELES BASIN.
...PORTIONS OF WRN TX FROM THE PECOS VALLEY TO THE BIG COUNTRY...
NEAR-RECORD WARM TEMPERATURES /IN THE MIDDLE 70S TO LOWER 80S/ WILL
LEAD TO WIDESPREAD LOW RH FROM 8 TO 15 PERCENT THIS AFTERNOON.
HOWEVER...MODEL FORECASTS REMAIN CONSISTENT WITH DIMINISHING
LOW-LEVEL FLOW DURING THE AFTERNOON AS A COLD FRONT QUICKLY
APPROACHES. SUSTAINED SURFACE WINDS SHOULD REMAIN MODERATE
/AVERAGING 15 TO 20 MPH/...AND WILL MITIGATE A CRITICAL AREA
ISSUANCE.

PERIOD WITH LITTLE OVERALL CHANGE TO THE SYNOPTIC REGIME. DIURNAL
OSCILLATIONS TO THE SURFACE PRESSURE GRADIENT WILL LEAD TO PERIODS
OF SUSTAINED WINDS FROM 20 TO 30 MPH GUSTING AOA 50 MPH. LITTLE IF
ANY RH RECOVERY AT NIGHT WILL RESULT IN LONG DURATIONS OF LOW RH
/AOB 15 PERCENT/...WITH MIN VALUES FROM 6 TO 10 PERCENT DURING THE
