   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0354 AM CDT FRI AUG 15 2008
   
   VALID 151200Z - 161200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER TROUGH OVER THE ROCKIES WILL SLOWLY MOVE SWD THROUGH THE
   PERIOD...WHILE STRONG UPPER RIDGING REMAINS OVER THE PAC NW. AS A
   RESULT...BELOW NORMAL TEMPERATURES WILL BE FOUND OVER THE
   CENTRAL/SRN ROCKIES AND THE PLAINS STATES. WELL ABOVE NORMAL
   TEMPERATURES WILL OCCUR FROM MUCH OF THE GREAT BASIN INTO THE PAC
   NW. LOW RH READINGS WILL COMBINE WITH THESE TEMPERATURES AND WEAK
   MID LEVEL WINDS TO PRODUCE HIGH HAINES INDICES OVER THIS REGION. A 
   A SLIGHT INCREASE IN MID LEVEL MOISTURE /ROTATING AROUND THE WRN
   PORTIONS OF THE UPPER RIDGE/ MAY SUPPORT ISOLATED DRY TSTMS OVER NRN
   CA/SRN ORE THIS AFTERNOON/OVERNIGHT. HOWEVER LIMITED COVERAGE WILL
   PRECLUDE ANY CRITICAL DRY TSTM THREAT. ELSEWHERE ACROSS THE
   NATION...NO OTHER AREAS OF FIRE WEATHER CONCERN WILL EXIST.
   
   ...INTERIOR PAC NW/NRN CA...
   VERY HOT TEMPERATURES /FROM 10-20 DEG ABOVE NORMAL/ WILL OCCUR TODAY
   AS A RESULT OF A STRONG UPPER RIDGE RESIDING OVER THE REGION.
   SEASONABLY LOW DWPTS WILL RESULT IN MIN RH READINGS FROM 10-15
   PERCENT OVER INTERIOR WA AND ORE. RELATIVELY LIGHT WINDS WILL
   PRECLUDE ANY CRITICAL FIRE WEATHER THREAT. MID LEVEL MOISTURE MOVING
   NWD THROUGH CENTRAL CA THIS MORNING WILL MOVE AROUND THE PERIPHERY
   OF THE UPPER RIDGE AND INTO NRN CA AND SRN ORE THIS AFTERNOON. AS A
   RESULT...ISOLATED DRY TSTMS ARE POSSIBLE OVER THE HIGHER TERRAIN OF
   THIS REGION. LACK OF AN ORGANIZED FORCING MECHANISM WILL PRECLUDE A
   CRITICAL FIRE WEATHER THREAT.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0356 AM CDT FRI AUG 15 2008
   
   VALID 161200Z - 171200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   THE UPPER AIR PATTERN WILL CHANGE LITTLE THROUGH TOMORROW ACROSS THE
   NATION. AN UPPER RIDGE WILL RESIDE OVER THE PAC NW AGAIN...LEADING
   TO ANOTHER DAY OF HOT TEMPERATURES IN THIS REGION. AHEAD OF A
   DEEPENING UPPER TROUGH OVER THE GULF OF ALASKA....A SHORTWAVE TROUGH
   OFF THE NRN CA COAST AT THE START OF THE PERIOD WILL MOVE INTO THE
   PAC NW DURING THE AFTERNOON HOURS. AHEAD OF THIS FEATURE...ISOLATED
   TO SCT DRY TSTMS ARE POSSIBLE OVER MUCH OF THE ORE/WA CASCADES AND
   PORTIONS OF ERN ORE AND WA...LEADING TO NEAR CRITICAL FIRE WEATHER
   CONDITIONS. ELSEWHERE ACROSS THE REMAINDER OF THE WEST...AN UPPER
   LOW WILL REMAIN NEARLY STATIONARY OVER THE CENTRAL ROCKIES
   ...PROVIDING FOR SCT PRECIPITATION OVER MUCH OF CENTRAL/SRN ROCKIES
   AND SRN PLAINS.
   
   ...NRN CA AND CENTRAL/ERN ORE AND WA...
   A SUBTLE SHORTWAVE OVER SRN CA THIS MORNING WILL MOVE NWD ALONG THE
   PERIPHERY OF THE UPPER RIDGE THROUGH TOMORROW. AS A RESULT...MID
   LEVEL MOISTURE WILL DEVELOP INTO A REGION OF A HOT BOUNDARY
   LAYER...LEADING TO THE DEVELOPMENT OF MODERATE INSTABILITY.
   RELATIVELY HIGH PWAT VALUES /AOA 1 INCH/ WILL LIMIT THE THREAT FOR
   DRY TSTMS OVER NRN CA. HOWEVER FURTHER NORTH...LOWER PWAT VALUES
   /LESS THAN 0.75 INCH/ WILL LEAD TO A MORE FAVORABLE ENVIRONMENT FOR
   DRY TSTMS OVER PORTIONS OF CENTRAL/ERN ORE AND WA. SUFFICIENT
   UNCERTAINTY EXISTS REGARDING THE COVERAGE OF TSTMS SUCH THAT A
   CRITICAL AREA WILL NOT BE DRAWN AT THIS TIME.
