   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0234 AM CDT SAT MAY 23 2009
   
   VALID 231200Z - 241200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   STRONG UPPER FLOW WILL GENERALLY REMAIN N OF THE U.S.-CANADA BORDER
   AS A WEAK UPPER TROUGH PER EARLY MORNING WATER VAPOR IMAGERY
   CONTINUES TO SLIDE EWD FROM THE ERN PACIFIC INTO THE PACIFIC NW.  A
   WEAK WAVE WILL MOVE ONSHORE THE NRN GULF OF MEXICO WITH HIGH
   PRESSURE SITUATED OVER THE WRN ATLANTIC.  SEVERAL WEAK IMPULSES WILL
   LEAD TO SCATTERED SHOWERS AND THUNDERSTORMS OVER PARTS OF THE
   INTERMOUNTAIN WEST.
   
   ...SERN ORE/NWRN NV/SWRN ID...
   LATEST OBSERVED RAOB DATA/GPS PRECIPITABLE WATER/SATELLITE IMAGERY
   SHOW A MORE MOIST AIRMASS HAS MOVED NW OVER CNTRL NV CHARACTERIZED
   BY PRECIPITABLE WATER AOA 0.60 INCH.  STEEP MID LEVEL LAPSE RATES ON
   PERIPHERY OF MOIST PLUME OVER THE GREAT BASIN WILL BE CONDUCIVE FOR
   WEAK CONVECTIVE INSTABILITY WITH STRONG DAYTIME HEATING.  DESPITE
   ONLY WEAK LARGE SCALE ASCENT ASSOCIATED WITH APPROACHING UPPER
   TROUGH...OROGRAPHIC ENHANCEMENT WILL TEND TO FAVOR STORM INITIATION
   OVER HIGHER TERRAIN.  WHILE POTENTIAL FOR DRY TSTMS MAY EXIST
   INITIALLY...FORECAST SOUNDINGS AND SLUG OF SLIGHTLY HIGHER MOISTURE
   QUALITY SEEM TO SUPPORT A DRY TO WET STORM EVOLUTION.  THIS WILL
   LIKELY RESULT IN A MORE TEMPERED OVERALL THREAT...ESPECIALLY IN
   COMBINATION WITH LIMITED FUEL RECEPTIVENESS.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0304 AM CDT SAT MAY 23 2009
   
   VALID 241200Z - 251200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A RELATIVELY QUIET FIRE WEATHER DAY IS EXPECTED AS A PORTION OF THE
   NRN BRANCH OF THE JET STREAM IS CONFINED TO ONTARIO AND AREAS E. 
   SEVERAL WEAK IMPULSES WILL BE LOCATED OVER NRN CA...NRN HIGH
   PLAINS...AND THE LOWER MS RIVER VALLEY/ARKLATEX REGIONS. 
   ISOLATED/SCATTERED SHOWERS AND THUNDERSTORMS ARE FORECAST TO
   ENCOMPASS A SIZEABLE AREA OF THE CONUS...IN ASSOCIATION WITH THE
   AFOREMENTIONED FEATURES.  A COLD FRONT WILL MOVE THROUGH NEW ENGLAND
   WITH GUSTY WINDS ACCOMPANYING IT...BUT TRAILING PORTION OF THE FRONT
   WILL STALL OVER THE OH VALLEY AND EXTEND WWD INTO THE N-CNTRL HIGH
   PLAINS.  SOME LOW POTENTIAL FOR INITIAL DRY TSTMS MAY EXIST IN AREAS
   OVER THE NWRN GREAT BASIN AND PARTS OF THE W COAST...BUT FUEL
   RECEPTIVENESS CONCERNS OR ISOLATED COVERAGE OF THREAT OR COMBINATION
   THEREOF WILL LIKELY LIMIT FIRE WEATHER CONCERNS.
