   VALID 021200Z - 031200Z

   ...CRITICAL FIRE WEATHER AREA FOR NERN ORE / W-CNTRL ID...

   ...SYNOPSIS...
   A LARGE-SCALE UPPER TROUGH WILL CONTINUE TO RESIDE OVER THE ERN HALF
   OF THE CONUS AND BE REINFORCED BY SEVERAL DISTURBANCES MOVING
   CYCLONICALLY THROUGH THE BASE OF THE TROUGH.  FARTHER WEST...AN
   UPPER RIDGE OVER THE INTERIOR WEST IS FIXED WHILE AN UPPER TROUGH
   MOVES THROUGH THE PACIFIC NW STATES TODAY AND TONIGHT.  ISOLATED TO
   SCATTERED DRY THUNDERSTORMS ARE FORECAST TODAY FROM PARTS OF THE
   NWRN GREAT BASIN TO THE ID/WA/BC BORDER REGION AND ISOLATED STORMS
   WILL LIKELY LINGER INTO THE NIGHT ACROSS A PORTION OF THIS REGION.

   ...NRN NV AND FAR NRN CA / E SLOPES OF THE CASCADES AND ADJACENT
   BASINS / LARGE PART OF ID...
   EARLY MORNING SATELLITE AND LIGHTNING DATA SHOW AN UPPER TROUGH NEAR
   THE ORE/WA COAST WITH SEVERAL SMALLER-SCALE DISTURBANCES MOVING
   ACROSS ERN ORE/NRN NV EARLY THIS MORNING /ASSOCIATED WITH LIGHTNING
   ACTIVITY/ AND ANOTHER UPSTREAM DISTURBANCE MOVING NEWD INTO NRN CA
   FROM THE ERN PACIFIC.  THE MID-LEVEL FEATURE OVER NRN CA IS FORECAST
   TO TRACK NEWD AND BISECT THE NWRN AND SERN PART OF ORE DURING PEAK
   HEATING.  LINEAR EXTRAPOLATION INDICATES THIS SPEED MAX AND
   ACCOMPANYING ASCENT WILL REACH THE NERN CA/ORE BORDER AT 15Z AND
   E-CNTRL ORE IN THE 21-23Z /AFTERNOON/ TIMEFRAME.  THE FAVORABLE
   TIMING OF THIS DISTURBANCE AND ADEQUATE MOISTURE OVER THE REGION
   WILL FAVOR ISOLATED TO SCATTERED THUNDERSTORMS DEVELOPING OVER MUCH
   OF THE DISCUSSION AREA DURING THE DAY.  A CONCENTRATED AREA OF
   SCATTERED DRY THUNDERSTORMS WILL LIKELY DEVELOP DURING THE AFTERNOON
   AND MOVE NEWD IN TANDEM WITH THE AFOREMENTIONED DISTURBANCE. 
   FORECAST SOUNDINGS SHOW STEEP LAPSE RATES WITH DEEP/WELL-MIXED
   BOUNDARY-LAYER PROFILES.  STORM MOTIONS FROM THE SOUTHWEST TO
   NORTHEAST OF 20-30 MPH ARE FORECAST AND WILL TEND TO LIMIT
   RAINFALL...DESPITE PW VALUES 0.6-1.0 INCH ACROSS THE REGION.
