   VALID 191200Z - 201200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A RELATIVELY BENIGN FIRE WEATHER PATTERN IS EXPECTED TODAY. AN
   UPPER-LEVEL RIDGE WILL REMAIN ANCHORED ACROSS THE LOWER MS RIVER
   VALLEY. AN UPPER-LEVEL LOW CENTERED OVER THE NRN GULF OF CA WILL
   GRADUALLY EJECT N/NEWD AS IT BECOMES ABSORBED BY A TROUGH DEEPENING
   ALONG THE W COAST.
   
   ...PORTIONS OF SERN AZ AND THE MOGOLLON RIM...
   THERE WILL BE POTENTIAL FOR MARGINALLY DRY TSTMS AROUND PEAK DIURNAL
   HEATING ON THE NWRN PERIPHERY OF RICHER MID-LEVEL MOISTURE SLOWLY
   INCREASING NWD. CONVECTIVE COVERAGE SHOULD REMAIN ISOLATED WHERE
   MODERATELY DEEP SUB-CLOUD LAYERS AND SURFACE RH AROUND 15 PERCENT
   EXIST.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0404 AM CDT FRI JUN 19 2009
   
   VALID 201200Z - 211200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER-LEVEL RIDGE WILL PERSIST OVER THE LOWER MS RIVER
   VALLEY...WHILE A LARGE-SCALE TROUGH /CONSISTING OF SEVERAL EMBEDDED
   WAVES/ EVOLVES OVER THE WRN CONUS. MODEL FORECASTS DIFFER
   SUBSTANTIALLY WITH THE HANDLING OF THE INDIVIDUAL EJECTING IMPULSES
   WITHIN THE LARGER-SCALE TROUGH...ESPECIALLY WITH THE SHORT WAVE
   EXPECTED TO HAVE THE GREATEST POTENTIAL IMPACT ON FIRE WEATHER.
   
   ...FAR SRN NV...
   19/00Z MODEL GUIDANCE INCONSISTENCIES ARE QUITE HIGH WITH RESPECT TO
   A SHORT WAVE TROUGH THAT SHOULD BE INVOF CNTRL CA EARLY SAT. THE
   ECMWF WAS MUCH SLOWER COMPARED TO THE GFS AND NAM IN THE RESULTANT
   EJECTION OF THIS TROUGH NEWD...WITH THE NAM DEPICTING THE MOST
   AMPLIFIED LOW/MID-LEVEL FLOW ACROSS THE SRN GREAT BASIN. THE 19/06Z
   NAM HAS NOW BACKED OFF ON EJECTION SPEED AND FLOW AMPLITUDE.
   CONSENSUS WOULD SUGGEST A SHORT-DURATION PERIOD OF SUSTAINED WINDS
   OF 20 TO 25 MPH WITH RH VALUES OF 15 PERCENT MAY DEVELOP IN THE LATE
   AFTERNOON ACROSS FAR SRN NV.
