   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0305 AM CDT SUN AUG 17 2008
   
   VALID 171200Z - 181200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   THE UPPER LEVEL WEATHER PATTERN ACROSS THE CONUS WILL CHANGE LITTLE
   DURING THE FORECAST PERIOD WITH A UPPER LEVEL LOW CENTERED OVER
   COLORADO...A RIDGE OVER THE GREAT BASIN...AND A TROUGH OVER THE
   NORTHEAST U.S. IN THE PACIFIC NORTHWEST...THE RIDGE THAT HAS BEEN IN
   PLACE FOR THE PAST FEW DAYS WILL BREAK DOWN AS A TROUGH ENTERS THE
   REGION FROM THE WEST...BRINGING THE POTENTIAL FOR DRY THUNDERSTORMS
   TO THE AREA. WIDESPREAD PRECIPITATION WILL EXIST ALONG A STATIONARY
   FRONT FROM NEW MEXICO...TO ALONG THE GULF COAST...TO THE SOUTHEAST
   STATES...AS WELL AS ACROSS THE SOUTHERN PLAINS DUE TO INFLUENCE FROM
   THE UPPER LOW OVER COLORADO. TROPICAL STORM FAY IS FORECAST TO
   BECOME A HURRICANE AND MOVE TO OFF THE WEST COAST OF
   FLORIDA...BRINGING HEAVY RAIN TO THE REGION.
   
   ...NRN CA/CNTRL AND ERN WA/OR...
   AS THE UPPER LEVEL TROUGH OFF THE PACIFIC NORTHWEST COAST BEGINS TO
   MOVE INLAND...A SHORTWAVE THROUGH WILL ROTATE AROUND ITS BASE INTO
   NORTHERN CALIFORNIA AND HELP PROVIDE A REGION OF LIFT FOR
   THUNDERSTORM DEVELOPMENT. IN ADDITION...A SOUTHWESTERLY FETCH OF
   MOISTURE WILL MOVE IN AHEAD OF THE TROUGH...AIDING IN INCREASING
   INSTABILITY. SOME DRY THUNDERSTORMS WILL FORM OVER THE HIGHER
   TERRAIN OF THE SIERRAS AND CASCADES DURING LATE AFTERNOON AND
   EVENING ON SUNDAY...BUT COVERAGE IS EXPECTED TO REMAIN FAIRLY
   LIMITED SO A CRITICAL FIRE WEATHER AREA WILL NOT BE OUTLINED. VERY
   HIGH AND UNSEASONABLY WARM SURFACE TEMPERATURES WILL ALSO CONTINUE
   IN A THERMAL TROUGH THAT WILL EXIST OVER EASTERN WA AND OR...WITH
   TEMPERATURES AROUND 100F AND RELATIVE HUMIDITY VALUES FROM 10 TO 20
   PERCENT. THE REGION WILL APPROACH CRITICAL FIRE WEATHER LIMITS...BUT
   THE WEAK WIND SPEEDS /AROUND 5 TO 15 MPH/ WILL PRECLUDE A RISK AREA.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0354 AM CDT SUN AUG 17 2008
   
   VALID 181200Z - 191200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   THE UPPER LEVEL LOW OVER COLORADO WILL CONTINUE TO SLOWLY MOVE TO
   THE SOUTHEAST TO THE OKLAHOMA PANHANDLE DURING THE FORECAST
   PERIOD...WITH CONTINUED THUNDERSTORMS AND RAIN IN THE SOUTHERN
   PLAINS. IN THE PACIFIC NORTHWEST...THE UPPER LEVEL TROUGH OFF THE
   COAST WILL MOVE INLAND BRINGING THUNDERSTORMS TO THE REGION.
   ADDITIONALLY...A CONTINUED STATIONARY FRONT ALONG MUCH OF THE GULF
   COAST WILL PROVIDE A FOCUS FOR CONTINUED AFTERNOON
   THUNDERSTORMS...AND TROPICAL STORM /POSSIBLE HURRICANE/ FAY WILL
   MOVE TO JUST OFF THE SOUTHWEST COAST OF FLORIDA.
   
   ...NRN CA/ERN AND CNTRL OR/WA...
   AS IN PREVIOUS DAYS...THIS AREA WILL BE AT A CONTINUED RISK FOR DRY
   THUNDERSTORMS. COVERAGE OF STORMS IS MORE CERTAIN ON MONDAY AS THE
   UPPER LEVEL TROUGH MAKES MUCH MORE OF AN IMPACT ON THE REGION...BUT
   WITH INCREASING MOISTURE FROM THE SOUTH THE CHANCE FOR A SIGNIFICANT
   AMOUNT AND WIDESPREAD COVERAGE OF DRY THUNDERSTORMS APPEARS TO BE
   BELOW CRITICAL THRESHOLDS...AS THUNDERSTORMS COULD ALSO APPROACH
   SEVERE CRITERIA /ESPECIALLY OVER WA AND OR/ GIVEN THE INCREASING
   AMOUNT OF SHEAR AS THE TROUGH MOVES INLAND. THE AREA COULD BE
   UPGRADED TO A CRITICAL DRY THUNDERSTORM RISK ON DAY 1 IF IT APPEARS
   THAT MOISTURE WILL BE LESS THAN CURRENTLY FORECAST AND DRY
   THUNDERSTORM COVERAGE WILL BE GREATER.
