   DAY 1 FIRE WEATHER OUTLOOK...REF AWIPS GRAPHIC PMWE98 KWNS
   VALID 071200-081200
     
   ...NO LARGE-SCALE SIGNIFICANT FIRE WEATHER CONDITIONS EXPECTED...
     
   ...SYNOPSIS... 
   NWRN U.S. TROUGH WILL SLOWLY MOVE EWD THROUGH THE DAY...CAUSING
   MORE THUNDERSTORMS OVER MT.  WARM AND DRY AIR WILL REMAIN OVER THE
   GREAT BASIN AND SRN CAN AND WILL INFILTRATE NRN CA.  A LARGE AREA
   OF HIGH PRESSURE WILL DOMINATE THE WEATHER FROM THE GREAT LAKES SWD
   THROUGH THE APPALACHIANS...WHERE IT HAS BECOME DRY.    
     
   ...SRN VA / CENTRAL AND WRN CAROLINAS...
   HIGH PRESSURE WILL MAKE FOR CONTINUED LOW RH...WITH THE LOWEST
   LEVELS BEING REACHED THIS AFTERNOON.  MIN RH VALUES OF 20-30
   PERCENT ARE EXPECTED INTO SRN VA AND THE CENTRAL AND WRN CAROLINAS
   WHERE SEVERE DROUGHT CONDITIONS EXIST.  NLY WINDS OF 10-15 MPH WILL
   COMBINE WITH THE LOW RH TO PRODUCE MARGINALLY CRITICAL FIRE WEATHER
   CONDITIONS...ESPECIALLY IN AREAS THAT HAVE RECEIVED LITTLE
   PRECIPITATION DURING THE LAST TWO WEEKS.
   
   ...GREAT BASIN AREA AND POINTS WEST...
   LARGE SCALE SUSTAINED WINDS NEAR 15 MPH WILL BE COMMON OVER MOST OF
   THE GREAT BASIN DURING THE DAYTIME.  WARM TEMPERATURES AND A VERY
   DRY AIRMASS WILL MAKE FOR MODERATELY UNSTABLE CONDITIONS DURING THE
   AFTERNOONS.  FURTHER NW...AS HIGH PRESSURE BUILDS INTO
   WA/OR/ID...AN OFFSHORE COMPONENT TO THE WIND WILL DEVELOP OVER
   TIME.  THIS WILL HELP TO BRING VERY DRY AIR FROM ABOVE DOWN TO THE
   SURFACE AND MAKE FOR POOR OVERNIGHT RH RECOVERIES.  OFFSHORE FLOW
   WILL BECOME MORE PRONOUNCED OVER WRN OREGON AND NRN CA ON DAY TWO.

   DAY 2 FIRE WEATHER OUTLOOK...REF AWIPS GRAPHIC PMWI98 KWNS
   VALID 081200-091200
     
   ...NO LARGE-SCALE SIGNIFICANT FIRE WEATHER CONDITIONS EXPECTED...
     
   ...SYNOPSIS... 
   UPPER TROUGH WHICH HAS BEEN OVER THE PACIFIC NW WILL MOVE QUICKLY
   EWD INTO ERN MT BY FRIDAY MORNING.  ALONG WITH IT...RAIN AND
   THUNDERSTORMS.  BEHIND THIS TROUGH...HIGH PRESSURE WILL BUILD IN. 
   THE LEADING EDGE OF THIS HIGH WILL BE A COLD FRONT...WHICH WILL
   MOVE INTO THE WRN DAKOTAS AND ERN WY / WRN NEBRASKA BY THURSDAY
   AFTERNOON.  OFFSHORE WINDS WILL BE ENHANCED ALONG THE OREGON AND
   NRN CA COAST DUE TO THE PRESSURE GRADIENTS.  WINDY AND DRY
   CONDITIONS WILL OCCUR INTO WY.
     
   ...WYOMING...
   STRONG PRESSURE GRADIENTS ASSOCIATED WITH SURFACE HIGH WILL CAUSE
   WLY WINDS OF 20-30 MPH INTO WY.  RH LEVELS WILL BE
   MARGINAL...MOSTLY BETWEEN 20 AND 30 PERCENT...ALTHOUGH LOWER VALUES
   OF 15-20 PERCENT WILL OCCUR INTO SWRN WY.  CLOUDS AND PRECIPITATION
   CHANCES WILL BE MOST PREVALENT OVER NRN WYOMING...SO RH VALUES WILL
   REMAIN WELL ABOVE CRITICAL LEVELS IN THOSE AREAS.
   
   ...NRN CA / WRN OREGON...
   AS HIGH PRESSURE MOVES INTO ID AND WRN MT...GRADIENTS WILL BE SUCH
   THAT OFFSHORE FLOW WILL DEVELOP OVER WRN OREGON AND NRN CA.  THIS
   WILL HELP TO BRING VERY DRY AIR TO THE SURFACE...AND MAKE FOR MIN
   AFTERNOON RH VALUES NEAR 10 PERCENT.  WINDS ARE NOT FORECAST TO BE
   STRONG...BUT WILL BE LOCALLY GUSTY THROUGH PASSES.  OVERNIGHT
   RECOVERY WILL BE POOR AS ELY WINDS KEEP IT DRY.
