   ...CRITICAL FIRE WEATHER AREA FOR A LARGE PORTION OF THE GREAT BASIN
   AND CENTRAL ROCKIES...
   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE NRN HIGH PLAINS...
   
   ...SYNOPSIS...
   A STRONG UPPER TROUGH WILL DIG SEWD INTO THE PAC NW THROUGH THE
   PERIOD. AHEAD OF THIS UPPER SYSTEM AND ASSOCIATED COLD FRONT A LARGE
   AREA OF MODERATE SWLY WINDS COMBINED WITH LOW RH READINGS WILL
   SUPPORT CRITICAL FIRE WEATHER CONDITIONS FROM PORTIONS OF CA NEWD
   INTO WY. FURTHER EAST...A STRENGTHENING LEE TROUGH OVER THE HIGH
   PLAINS WILL SUPPORT INCREASING SLY WINDS OVER SD/ND. LOW RH READINGS
   ASSOCIATED WITH THESE WINDS WILL SUPPORT AN ADDITIONAL AREA OF
   CRITICAL FIRE WEATHER CONDITIONS. FURTHER SOUTH OVER THE CENTRAL/SRN
   PLAINS...DESPITE INCREASING SLY WINDS...MODERATE LOW LEVEL MOISTURE
   WILL PRECLUDE CRITICAL FIRE WEATHER CONDITIONS. ELSEWHERE ACROSS THE
   NATION...NO OTHER CRITICAL FIRE WEATHER CONDITIONS ARE EXPECTED.
   
   ...CRITICAL FIRE WEATHER AREA - PORTIONS OF CA NEWD INTO WY...
   
   PRIMARY CONDITIONS: SUSTAINED SWLY WINDS FROM 20-30 MPH WITH GUSTS
   OVER 40 MPH...MIN RH READINGS FROM 10-15 PERCENT
   
   AN UPPER TROUGH WILL DEVELOP SEWD THROUGH THE PAC NW TODAY. AHEAD OF
   AN ASSOCIATED COLD FRONT MOVING SEWD THROUGH THE GREAT
   BASIN...STRENGTHENING PRESSURE GRADIENT AND INCREASING MID LEVEL
   WIND FIELDS WILL TRANSLATE TO MODERATE SWLY SFC WINDS FROM PORTIONS
   OF NRN/CENTRAL INTERIOR CA NEWD INTO WY. ANTECEDENT LOW RH READINGS
   WILL COMBINE WITH THE WINDS TO PRODUCE CRITICAL FIRE WEATHER
   CONDITIONS. IN ADDITION...ISOLATED DRY TSTMS ARE EXPECTED OVER
   PORTIONS OF THE ERN GREAT BASIN WHERE MONSOONAL MOISTURE WILL
   DEVELOP AHEAD OF THE UPPER TROUGH/COLD FRONT.
   
   ...CRITICAL FIRE WEATHER AREA - PORTIONS OF WRN AND CENTRAL SD/ND...
   
   PRIMARY CONDITIONS: SUSTAINED SLY WINDS FROM 20-25 MPH WITH GUSTS
   OVER 30 MPH...MIN RH READINGS FROM 15-20 PERCENT
   
   A STRENGTHENING AREA OF LOW PRESSURE OVER CENTRAL MT COMBINED WITH A
   DEEPENING LEE TROUGH WILL SUPPORT MODERATE SUSTAINED SLY WINDS OVER
   20 MPH TODAY ACROSS THE NRN PLAINS. INCREASING MOISTURE WILL KEEP RH
   READINGS ABOVE CRITICAL LEVELS ACROSS ERN ND/SD. HOWEVER FURTHER
   WEST OVER CENTRAL/ERN SD AND ND...RH READINGS ARE EXPECTED TO BE
   LESS THAN 20 PERCENT SUPPORTING A CRITICAL FIRE WEATHER THREAT.

   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE NRN HIGH PLAINS...
   
   ...SYNOPSIS...
   A STRONG UPPER TROUGH WILL DIG SEWD INTO THE GREAT BASIN TOMORROW.
   AHEAD OF AN ASSOCIATED COLD FRONT...SWLY WINDS WILL REMAIN MODERATE
   OVER PORTIONS OF ERN CA...NV AND WRN UT. LOW RH READINGS WILL
   COMBINE WITH THESE WINDS TO SUPPORT A CRITICAL FIRE WEATHER THREAT.
   FURTHER EAST...ANOTHER DAY OF CRITICAL FIRE WEATHER CONDITIONS IS
   EXPECTED OVER THE NRN HIGH PLAINS SOUTH OF A COLD FRONT AND JUST
   EAST OF AN ASSOCIATED LEE TROUGH.
   
   ...CRITICAL FIRE WEATHER AREA - PORTIONS OF ERN CA...SRN/CENTRAL NV
   AND WRN UT...
   
   PRIMARY CONDITIONS: SUSTAINED SWLY WINDS FROM 20-30 MPH WITH GUSTS
   OVER 40 MPH...MIN RH READINGS FROM 10-15 PERCENT
   
   SIMILAR TO DAY 1...A STRONG UPPER TROUGH AND ASSOCIATED COLD FRONT
   WILL DIG SEWD THROUGH THE GREAT BASIN/ROCKIES ON DAY 2. MODERATE MID
   LEVEL SWLY WIND FIELDS AND A TIGHT SFC PRESSURE GRADIENT /ASSOCIATED
   WITH A LOW PRESSURE AREA OVER THE NRN GREAT BASIN/ WILL SUPPORT
   MODEST SWLY WINDS OVER THE ERN/SRN GREAT BASIN. THESE WINDS WILL
   COMBINE WITH LOW RH READINGS TO PRODUCE CRITICAL FIRE WEATHER
   CONDITIONS DURING THE AFTERNOON.
   
   ...CRITICAL FIRE WEATHER AREA - PORTIONS OF WRN SD/ND...
   
   PRIMARY CONDITIONS: SUSTAINED SLY WINDS FROM 20-25 MPH WITH GUSTS
