   NWS STORM PREDICTION CENTER NORMAN OK
   1229 AM CDT SUN JUL 06 2008
   
   VALID 061200Z - 071200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER TROUGH AXIS WILL EXTEND FROM THE GREAT LAKES REGION SWD
   THROUGH THE APPALACHIANS WITH WIDESPREAD THUNDERSTORMS ACROSS MUCH 
   OF THE EAST AND THE SOUTHEAST ONCE AGAIN.  
   
   TO THE WEST...AN UPPER TROUGH OVER THE INTERMOUNTAIN WEST WILL
   GRADUALLY WEAKEN AND SHIFT EWD. HIGH PRESSURE WILL THEN DOMINATE
   WITH HOT AND DRY CONDITIONS PERSISTING...ALTHOUGH WINDS ARE EXPECTED
   TO REMAIN BELOW CRITICAL THRESHOLDS. DRY THUNDERSTORMS MAY STILL BE 
   POSSIBLE ACROSS PORTIONS OF ERN NV/UT/NRN AZ/WRN NM/CO.
   
   ...PORTIONS OF THE GREAT BASIN...
   WV IMAGERY EARLY THIS MORNING SHOWS A SHORT WAVE UPPER TROUGH SLOWLY
   PROGRESSING EWD INTO NV. TEMPERATURES ARE EXPECTED TO WARM INTO THE
   UPPER 80S TO LOWER 90S WITH RELATIVE HUMIDITIES IN THE TEENS ACROSS
   PORTIONS OF NV/UT. THIS SHORT WAVE WILL INDUCE THUNDERSTORM
   DEVELOPMENT BY LATE AFTERNOON...MAINLY OVER ERN NV AND UT...HOWEVER
   COVERAGE IS EXPECTED TO BE ISOLATED DUE TO LIMITED INSTABILITY. 
   
   ...FARTHER EAST IN NRN AZ/SERN UT/WRN NM/CO...
   MORE WIDESPREAD THUNDERSTORM COVERAGE IS EXPECTED IN THE AFTERNOON
   RELATIVE TO AREAS TO THE W...ALTHOUGH RELATIVE HUMIDITIES AT THE
   SURFACE WILL BE ABOVE CRITICAL THRESHOLDS. FURTHERMORE...MOISTURE
   TRANSPORT FROM THE S AND EXISTING MOISTURE HAVE CONTINUED TO KEEP
   ABOVE NORMAL PWATS OVER THE AREA...REFLECTED IN LATEST 00Z SOUNDING
   DATA WITH VALUES NEAR .75 INCH TO AN INCH. GIVEN A FAIRLY MOIST
   AIRMASS...THUNDERSTORMS THAT DO DEVELOP SHOULD BE OF MORE WET NATURE
   VS DRY...ALTHOUGH LIGHTNING STRIKES WILL INCREASE THE RISK OF FIRE
   STARTS.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0141 AM CDT SUN JUL 06 2008
   
   VALID 071200Z - 081200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   IN UPPER LEVELS...THE OVERALL PATTERN WILL CONTINUE TO
   DEAMPLIFY...ALTHOUGH WEAK EMBEDDED LOWS WILL TRIGGER SHOWERS AND
   THUNDERSTORMS IN THE EAST AND SOUTHEAST...AND THROUGH PORTIONS OF
   THE NRN AND HIGH PLAINS.
   
   MEANWHILE IN THE WEST...RIDGING ALOFT WILL GRADUALLY BUILD...WITH
   HOT AND DRY CONDITIONS AT THE SURFACE PERSISTING. WINDS ARE EXPECTED
   TO REMAIN BELOW CRITICAL THRESHOLDS. ACROSS PORTIONS OF SRN
   NV/CA...AZ/NM/UT/CO THUNDERSTORMS WILL DEVELOP ONCE AGAIN ALTHOUGH
   THESE WILL MAINLY BE WET RATHER THAN DRY.
   
   ...SERN UT/WRN CO/NWRN NM/NRN AZ...
   THUNDERSTORMS WILL DEVELOP ONCE AGAIN BY AFTERNOON AS A MOIST
   AIRMASS LINGERS OVER THE AREA. FORECAST PWATS SUGGEST THAT
   THUNDERSTORMS WILL GENERALLY BE WET. SURFACE RH WILL REMAIN ABOVE
   CRITICAL THRESHOLDS WHILE WINDS ARE FORECAST TO REMAIN BELOW.
   
   ...SRN NV/CA/WRN AZ...
   PREEXISTING MOISTURE AND WEAK MOISTURE ADVECTION MAY ALLOW FOR
   SUFFICIENT MID LEVEL MOISTURE FOR THUNDERSTORM FORMATION IN A WEAKLY
   UNSTABLE ATMOSPHERE AS SURFACE TEMPERATURES CLIMB INTO THE LOWER
   100S TO NEAR 110 DEGREES. SURFACE RH WILL REMAIN IN THE
   TEENS...WHILE DEEP MIXING WILL PROMOTE GUSTY WINDS AT THE SURFACE.
   THERE IS CONSIDERABLE UNCERTAINTY IN REGARDS TO THE COVERAGE OF
   THUNDERSTORMS AND ATTM EXPECT ISOLATED DRY THUNDERSTORMS AT BEST.
