   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0110 AM CDT MON JUL 07 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 AZ/NM/UT/CO
   THUNDERSTORMS WILL DEVELOP ONCE AGAIN ALTHOUGH THESE WILL MAINLY BE
   WET RATHER THAN DRY. HOWEVER...IN EXTREME SERN CA/SWRN AZ AND SRN
   NV...ISOLATED DRY THUNDERSTORMS WILL BE POSSIBLE.
   
   ...SERN UT/WRN CO/NWRN NM/AZ...
   THUNDERSTORMS WILL DEVELOP ONCE AGAIN BY AFTERNOON AS A MOIST
   AIRMASS LINGERS OVER THE AREA. FORECAST/CURRENT PWATS SUGGEST THAT
   THUNDERSTORMS WILL GENERALLY BE WET. SURFACE RH WILL REMAIN ABOVE
   CRITICAL THRESHOLDS WHILE WINDS ARE FORECAST TO REMAIN BELOW.
   ADDITIONALLY...RAINFALL RECEIVED OVER THE PAST FEW DAYS SHOULD HELP
   TO MITIGATE THE FIRE THREAT...ALTHOUGH LIGHTNING STARTS MAY STILL BE
   POSSIBLE.
     
   ...SERN CA/SRN NV/EXTREME SWRN 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 TO 105 TO NEAR 115
   DEGREES. SURFACE RH WILL REMAIN IN THE TEENS. IF THUNDERSTORMS ARE
   ABLE TO FORM...THEY WILL PRIMARILY BE OF DRY NATURE. GUSTY AND
   ERRATIC WINDS CAN BE EXPECTED WHILE LIGHTNING STARTS WILL BE
   POSSIBLE.
   
   ...CA/OR/NV...
   VERY DRY AND SUBSIDENT AIRMASS UNDER UPPER RIDGING WILL ALLOW WELL
   ABOVE NORMAL TEMPERATURES TO CONTINUE. DESPITE HOT
   TEMPERATURES...WINDS WILL REMAIN LIGHT.

   DAY 2 FIRE WEATHER OUTLOOK RESENT 1
   NWS STORM PREDICTION CENTER NORMAN OK
   0322 AM CDT MON JUL 07 2008
   
   VALID 081200Z - 091200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   IN THE UPPER LEVELS...THE JET STREAM WILL CONTINUE TO REMAIN CLOSE
   TO THE U.S./CANADIAN BORDER...WITH THE STRONGEST WINDS ACROSS THE
   NRN MOST STATES. EMBEDDED DISTURBANCES WITHIN THE UPPER FLOW WILL
   INDUCE SHOWERS AND THUNDERSTORMS ACROSS MUCH OF THE ERN/SERN U.S.
   AND FROM THE HIGH PLAINS EXTENDING NEWD INTO THE GREAT LAKES REGION.
   
   MEANWHILE IN THE WEST...HIGH PRESSURE ALOFT WILL CONTINUE TO BUILD
   AND SPREAD EWD...WITH WELL ABOVE NORMAL TEMPERATURES AND DRY
   CONDITIONS AT THE SURFACE. STRONGER WINDS MAY BE POSSIBLE NEAR THE
   WA/OR/FAR NRN CA COASTS AS THE LOW LEVEL PRESSURE GRADIENT
   INCREASES.
   
   IN PORTIONS OF THE SWRN STATES...THUNDERSTORMS WILL DEVELOP IN THE
   AFTERNOON AND PERSIST INTO THE EARLY MORNING IN PORTIONS OF
   AZ/NM/UT/CO ONCE AGAIN...ALTHOUGH GIVEN PREEXISTING MOISTURE STORMS
   WILL GENERALLY BE WET. IN EXTREME SWRN AZ/SERN CA ISOLATED DRY
   THUNDERSTORMS MAY DEVELOP.
   
   ...EXTREME SERN CA/SWRN AZ...
   VERY WEAK MOISTURE ADVECTION INTO SERN CA/SWRN AZ WILL CONTINUE
   THROUGH DAY 1 AND INTO DAY 2. SLIGHT INCREASE IN MID LEVEL MOISTURE
   COMBINED WITH WEAK INSTABILITY MAY BE SUFFICIENT TO GENERATE DRY
   THUNDERSTORMS BY LATE AFTERNOON. GIVEN HOT AND DRY CONDITIONS AT THE
   SURFACE WITH TEMPERATURES NEAR 105 TO 115 AND RELATIVE HUMIDITIES IN
   THE TEENS...DRY THUNDERSTORMS WILL CERTAINLY ENHANCE FIRE DANGER
   WITH GUSTY AND ERRATIC WINDS NEAR THE STORMS AND FIRE STARTS
   POSSIBLE. ATTM UNCERTAINTIES ARE TOO GREAT IN REGARDS TO CONVECTIVE
   COVERAGE...AND SEEM ISOLATED AT BEST...THEREFORE LIMITING A DRY
   THUNDER DESIGNATION AT THIS TIME.
   
   ...WRN OR/EXTREME NWRN CA...
   AS HIGH PRESSURE CONTINUES TO BUILD EWD...HOT AND DRY CONDITIONS
   WILL PERSIST AT THE SURFACE IN A DRY AND SUBSIDENT REGIME. THE
   PRESSURE GRADIENT AT THE SURFACE NEAR THE COAST WILL INCREASE...WITH
   WINDS NEAR 20 TO 25 MPH POSSIBLE. BEST JUXTAPOSITION OF STRONG WINDS
   AND LOW RH APPEARS TO BE IN THE COASTAL VALLEYS.
