   VALID 041200Z - 051200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   SRN HALF OF AMPLIFIED POSITIVE TILT UPPER TROUGH OVER THE CNTRL U.S.
   WILL QUICKLY PIVOT EWD ACROSS THE SRN HIGH PLAINS TO THE DEEP SOUTH
   AS A VIGOROUS UPSTREAM SHORTWAVE TROUGH MOVES INTO THE PACIFIC NW
   FROM BRITISH COLUMBIA.  EARLY MORNING SURFACE ANALYSIS PLACES THE
   CENTROID OF HIGH PRESSURE INVOF WRN WY WITH A WEAK INVERTED PRESSURE
   TROUGH NWWD ALONG PORTIONS OF THE CA COAST.  THIS WILL SUPPORT SOME
   GUSTY OFFSHORE WINDS OVER PARTS OF COASTAL SRN CA MAINLY IN THE
   MORNING HOURS BEFORE SUBSIDING THEREAFTER.
   
   ...SRN CA COASTAL RANGES FROM THE SAN BERNARDINO MTNS SWD...
   HIGH MODEL VARIABILITY STILL EXISTS WITH REGARD TO THE STRENGTH OF
   THE OFFSHORE WINDS THIS MORNING OVER THE REGION.  GUSTY ENELY/S WILL
   PROBABLY DEVELOP OR BE ONGOING IN FAVORED TERRAIN AREAS AT THE START
   OF THE D1 PERIOD--WITH 06Z/04 RUC FORECAST SOUNDINGS FAVORING THIS
   SCENARIO.  THIS WILL TEMPORARILY ELEVATE THE FIRE WEATHER THREAT
   ACROSS THE REGION.  WITH THAT SAID...LIMITING FACTORS INCLUDE 1)
   RELATIVELY COOL TEMPS IN THE 40S/50S DURING THE PERIOD OF STRONGEST
   WINDS PRIOR TO 17Z 2) CRITICALLY LOW RH DEVELOPING NEAR THE END OF
   THE STRONGEST WINDS /15Z AND LATER/.  LITTLE OVERLAP OF EXPECTED
   CONDITIONS /LOW RH AND STRONG WINDS/ PRECLUDE A MORE ROBUST FIRE
   WEATHER SCENARIO AND A CRITICAL ISSUANCE.
