   VALID 021200Z - 031200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A STRONG SHORTWAVE TROUGH WILL MOVE ONSHORE THE PACIFIC NW WEDNESDAY
   NIGHT AS AN ANTICYCLONE REMAINS OVER THE DESERT SW.  STRENGTHENING
   KINEMATIC FIELDS IN ASSOCIATION WITH APPROACHING SYSTEM FROM THE W
   WILL OVERSPREAD PARTS OF THE PACIFIC NW.  AN ANTECEDENTLY DRY
   AIRMASS OVER THE NWRN GREAT BASIN WILL COMBINE WITH STRONG WINDS
   LEADING TO AN ENHANCED FIRE WEATHER THREAT OVER PORTIONS OF
   CA/NV/ORE.
   
   ...S-CNTRL ORE / NERN CA / EXTREME NWRN NV...
   PLAN VIEW DETERMINISTIC DATA SHOW THE STRONGEST H7 FLOW ALONG AND W
   OF THE ORE CASCADES /UP TO 50 KTS BY 00Z/ WITH WEAKER FLOW E OF THE
   HIGHER TERRAIN.  MODELS CONTINUE TO VARY SOME IN THE STRENGTH OF THE
   SUSTAINED SSWLY SURFACE WINDS.  NONETHELESS STRONG WINDS OF 20-30
   MPH ARE POSSIBLE WITH GUSTS UP TO 40 MPH.  LOW RH /LESS THAN 15
   PERCENT/ APPEARS TO BE UNLIKELY EXCEPT PERHAPS IN LOCALIZED AREAS
   WITH MID-UPPER TEENS TO LOWER 20S PERCENT MORE LIKELY BEFORE DIURNAL
   COOLING OCCURS.  THE COMBINATION OF POTENTIAL FOR STRONG
   WINDS/MARGINALLY LOW RH SUGGEST LOCALIZED CRITICAL CONDITIONS ARE
   POSSIBLE...BUT LIMITED SPATIAL/TEMPORAL NATURE OF THREAT WILL
   PRECLUDE A CRITICAL DESIGNATION.
   
   ...SRN CA...
   IN ADDITION TO THE VERY WARM TEMPS AND LOWER RH FORECAST OVER THE
   REGION...POTENTIAL FOR ISOLD TSTMS SEEMS TO EXIST IN THE LATE
   AFTERNOON AND/OR EARLY EVENING HOURS.  LATEST 4KM RESOLUTION MODEL
   DATA /NSSL WRF/ INDICATES NON-ZERO POTENTIAL FOR A STRAY TSTM AS FAR
   NW AS THE HIGHER TERRAIN E OF THE LOS ANGELES BASIN.  GUSTY/ERRATIC
   WINDS CAN ACCOMPANY ANY TSTM OR SURGING OUTFLOW.
