   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0123 AM CDT THU JUN 19 2008
   
   VALID 191200Z - 201200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   THE OVERALL PATTERN WILL REMAIN MOSTLY UNCHANGED. AN UPPER TROUGH
   WILL DOMINATE THE EAST WHILE DRY CONDITIONS WILL PERSIST IN THE SERN
   STATES IN A PREDOMINANT NWLY/WLY FLOW.
     
   A FLATTENED RIDGE WILL REMAIN OVER THE NRN GREAT BASIN...WHILE HOT
   AND DRY CONDITIONS WILL PERSIST OVER MUCH OF CA EWD INTO THE GREAT
   BASIN AND THE FOUR CORNERS STATES. 
   
   MEANWHILE...A LOW SEEN ON SATELLITE OFFSHORE OF BRITISH COLUMBIA
   WILL SLOWLY BEGIN TO DEEPEN AND SAG SOUTHWARD...SETTING UP FOR A
   BREAKDOWN OF THE RIDGE IN THE PACIFIC NW.
   
   ...INLAND NC/SC/SRN GA/AL/INLAND FL PANHANDLE...
   DRIER AIR WILL PERSIST OVER THE AREA IN A PREDOMINANT NWLY/WLY FLOW
   AND FOLLOWING THE PASSAGE OF A COLD FRONT. AFTERNOON TEMPERATURES IN
   THE 80S AND LOWER 90S WILL ALLOW RELATIVE HUMIDITIES TO DROP INTO
   THE UPPER TEENS AND 20S INLAND...AND LOWER 30S IN AREAS CLOSER TO
   THE COAST AWAY FROM SEA BREEZE INFLUENCE. ALTHOUGH WINDS WILL BE
   LIGHT...A LARGE PORTION OF THE SEE TEXT AREA REMAINS DRY WITH RECENT
   LACK OF RAINFALL...WHICH WILL HEIGHTEN THE FIRE WEATHER THREAT.
     
   ...CA/NV/UT/AZ/WRN CO/NM...
   VERY HOT AND DRY WEATHER WILL PERSIST UNDER THE UPPER RIDGE...WITH A
   HIGH HAINES INDEX DURING THE AFTERNOON. MIN RH IN THE SINGLE DIGITS
   TO LOWER TEENS WILL BE COMMON ONCE AGAIN. DUE TO STRONG
   INSTABILITY...LOCALLY GUSTY WINDS WILL BE LIKELY DURING THE
   AFTERNOON...BUT SUSTAINED WINDS WILL REMAIN BELOW CRITICAL
   THRESHOLDS. STILL...THE HOT AND DRY WEATHER WILL FAVOR AFTERNOON
   FIRE GROWTH WITH ANY ONGOING FIRES. RELATIVE HUMIDITIES WILL HAVE
   LITTLE RECOVERY OVERNIGHT ACROSS PORTIONS OF CA/AZ/NM AND SRN NV/UT.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0146 AM CDT THU JUN 19 2008
   
   VALID 201200Z - 211200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   IN THE EAST...THE UPPER TROUGH WILL DOMINATE WHILE THE SERN STATES
   WILL EXPERIENCE ANOTHER DAY OF CRITICALLY LOW RHS IN A PREDOMINANT
   NWLY/WLY FLOW. 
   
   IN THE WEST...THE LOW SITUATED OFFSHORE OF BRITISH COLUMBIA WILL
   BEGIN TO DEEPEN AND MOVE ONSHORE AS A JET AXIS DIGS INTO THE
   BACKSIDE OF THE TROUGH. THIS WILL BEGIN A BREAKDOWN OF THE RIDGE
   OVER THE PACIFIC NORTHWEST...AND ALLOW FOR SWLY WINDS TO OVERSPREAD
   NRN CA/NV AND OR/WA/ID.
   
   ...INLAND NC/SC/GA/AL/NRN FL...
   PREDOMINANT NWLY/WLY FLOW WILL ALLOW FOR THE DRIER AIR MASS TO
   PERSIST FOR ONE MORE DAY. TEMPERATURES IN THE 80S AND LOWER 90S WILL
   ALLOW AFTERNOON RELATIVE HUMIDITIES TO DROP INTO THE MID TO UPPER
   20S...WHILE CLOSER TO THE COAST RELATIVE HUMIDITIES NEAR 30 TO 35
   WILL BE LIKELY. DESPITE LIGHT WINDS...LACK OF RECENT RAINFALL AND
   DROUGHT CONDITIONS ACROSS A LARGE PORTION OF THE SOUTHEAST WILL
   ENHANCE THE FIRE THREAT. 
   
   ...PORTIONS OF THE PACIFIC NORTHWEST...
   THE LOW OFFSHORE OF BRITISH COLUMBIA WILL FINALLY BEGIN TO SHIFT
   ONSHORE...OVERSPREADING SWLY WINDS ACROSS A LARGE AREA. ALTHOUGH
   SUSTAINED WINDS WILL BE SOMEWHAT MARGINAL...STEEP LOW LEVEL LAPSE
   RATES AND DEEP MIXING WILL PROMOTE GUSTY WINDS...ESPECIALLY ON THE
   ERN SLOPES OF THE CASCADES. TEMPERATURES IN THE 80S TO 90S WITH
   RELATIVE HUMIDITIES IN THE TEENS WILL BE COMMON.
   
   ...SWRN STATES...
   HOT AND DRY CONDITIONS WILL CONTINUE UNDER AN UPPER RIDGE. STRONG
   HEATING AND SURFACE TEMPERATURES INTO THE UPPER 90S TO NEAR 115 F
   WILL ENHANCE FIRE THREAT IN RAIN PARCHED AREAS DESPITE LIGHT WINDS.
