   DAY 1 FIRE WEATHER OUTLOOK...REF AWIPS GRAPHIC PMWE98 KWNS
   VALID 251200-261200
   
   ...NO LARGE-SCALE SIGNIFICANT FIRE WEATHER CONDITIONS EXPECTED...
     
   ...SYNOPSIS... 
   ANOTHER SHORTWAVE TROUGH WILL MOVE INTO THE SWRN STATES THROUGH THE
   PERIOD. MUCH OF THE NRN/ERN HALF OF THE NATION WILL REMAIN UNDER
   BELOW NORMAL TEMPERATURES THROUGH THE PERIOD. 
   
   ...SRN GREAT BASIN/WRN AZ AND SERN CA...
   AFTERNOON SSWLY BREEZES FROM 15 TO 20 MPH WILL BE POSSIBLE ALONG
   WITH MINIMUM RH VALUES FROM 20 TO 30 PERCENT AS A SURFACE PRESSURE
   TROUGH DEEPENS OVER THE LOWER CO RIVER VALLEY. ADDITIONALLY...
   ISOLATED TO WIDELY SCATTERED THUNDERSTORMS WILL LIKELY DEVELOP
   AHEAD OF THE SYSTEM WHERE STRONG FORCING WILL INTERACT WITH MID
   LEVEL MOISTURE/INSTABILITY. CLOUD BASES AROUND 10 KFT ALONG WITH
   MEAN SUB-CLOUD RH READINGS AROUND 30 PERCENT WILL FAVOR THE
   POTENTIAL FOR A FEW DRY THUNDERSTORMS.

   DAY 2 FIRE WEATHER OUTLOOK...REF AWIPS GRAPHIC PMWI98 KWNS
   VALID 261200-271200
     
   ...NO LARGE-SCALE SIGNIFICANT FIRE WEATHER CONDITIONS EXPECTED...
     
   ...SYNOPSIS... 
   MID/UPPER SYSTEM WILL ONLY MOVE SLOWLY EWD ACROSS THE SOUTHWEST
   THROUGH THE PERIOD. BUILDING LOW TO MID LEVEL RIDGING BEHIND THIS
   SYSTEM WILL PROVIDE FOR WEAK OFFSHORE EVENT OVER NRN CA. AREAS OF
   PRECIPITATION CAN BE EXPECTED OVER MUCH OF THE SRN PLAINS. BELOW
   NORMAL TEMPERATURES WILL CONTINUE OVER MUCH OF THE NRN HALF OF THE
   COUNTRY. 
   
   ...SRN AZ...
   AHEAD OF SLOW MOVING MID LEVEL TROUGH DEEP LOW LEVEL MIXING WILL
   AID IN MINIMUM RH READINGS AROUND 20 PERCENT. SUSTAINED SWLY WINDS
   FROM 15 TO 20 MPH WILL PROVIDE FOR NEAR CRITICAL FIRE WEATHER
   CONDITIONS. HOWEVER...LOW TO MODERATE FIRE DANGER RATINGS SUGGEST
   THAT OVERALL CRITICAL FIRE THREAT SHOULD BE MINIMAL.
   
   ...NRN CA...
   A DEEP LAYER OF NELY GRADIENT WINDS WILL DEVELOP OVER THE AREA
   DURING THE LATER HALF OF THE PERIOD...AS THE MID/UPPER LOW
   PROGRESSES INTO AZ/SRN GREAT BASIN. DESPITE EXPECTED INCREASE IN
   LOW LEVEL WINDS AND POOR RH RECOVERY OVER THE HIGHER TERRAIN ABOVE
   THE NOCTURNAL INVERSION...LOW TO MODERATE FIRE DANGERS WILL
   PRECLUDE A CRITICAL FIRE WEATHER THREAT.
