   VALID 161200Z - 171200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER LEVEL RIDGE WILL REMAIN OVER THE PACIFIC NORTHWEST AND VERY
   HOT SURFACE TEMPERATURES AND DRY HUMIDITY VALUES WILL CONTINUE IN
   NORTHERN CALIFORNIA...WASHINGTON...AND OREGON...WITH NEAR CRITICAL
   FIRE WEATHER CONDITIONS. HOWEVER...THIS RIDGE WILL ERODE SLIGHTLY
   DURING THE LATTER HALF OF THE FORECAST PERIOD AS A UPPER LEVEL
   THROUGH BEGINS TO IMPACT THE AREA...AND AHEAD OF THIS SYSTEM...A
   SLIGHT CHANCE OF DRY THUNDERSTORMS IS POSSIBLE SATURDAY AFTERNOON
   AND EVENING. ELSEWHERE IN THE COUNTRY...A NEARLY STATIONARY UPPER
   LOW WILL CONTINUE OVER COLORADO BRINGING RAIN AND THUNDERSTORMS TO
   THE CENTRAL AND SOUTHERN ROCKIES. IN THE SOUTHEAST...REGIONS OF RAIN
   AND THUNDERSTORMS ARE POSSIBLE ALONG A STATIONARY FRONT FROM TEXAS
   TO THE EAST COAST.
   
   ...ERN/CNTRL WA AND OR/NRN CA...
   HOT AND DRY CONDITIONS WILL EXIST AT THE SURFACE UNDER THE UPPER
   LEVEL RIDGE...AS A THERMAL SURFACE PRESSURE TROUGH MOVES THROUGH THE
   CASCADES ON SATURDAY AFTERNOON. RELATIVE HUMIDITY VALUES WILL DROP
   TO 10 TO 20 PERCENT AS TEMPERATURES CLIMB TO THE UPPER 90S F.
   HOWEVER...WIND SPEEDS WILL BE FAIRLY LIGHT. SOME MOISTURE WILL
   SPREAD INTO THE REGION AHEAD OF TROUGH THAT WILL BEGIN TO MOVE INTO
   THE REGION...SO THUNDERSTORMS WILL BE POSSIBLE...BUT COVERAGE IS
   EXPECTED TO REMAIN LIMITED AND CONFINED TO LATER IN THE PERIOD. A
   FEW DRY THUNDERSTORMS COULD BE POSSIBLE IN AREAS OF HIGHEST
   INSTABILITY AND WHERE MOISTURE WILL BE SOMEWHAT LIMITED...ESPECIALLY
   OVER EASTERN WA AND OR. CONDITIONS WILL APPROACH CRITICAL FIRE
   WEATHER VALUES...BUT UNCERTAINTY IN DRY THUNDERSTORM
   COVERAGE/POTENTIAL AND WEAK SURFACE WINDS PREVENT A RISK AREA AT
   THIS TIME.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0357 AM CDT SAT AUG 16 2008
   
   VALID 171200Z - 181200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   THE UPPER LEVEL RIDGE IN THE PACIFIC NORTHWEST WILL START TO BREAK
   DOWN AS A TROUGH MOVES IN FROM OFF THE WA/OR COAST. DRY
   THUNDERSTORMS WILL BE POSSIBLE SUNDAY AFTERNOON AND EVENING OVER NRN
   CA/ERN OR/WA AS MOISTURE MOVES INTO THE REGION AND AHEAD OF A
   SHORTWAVE TROUGH MOVING THROUGH THE AREA LATE IN THE PERIOD. THE
   UPPER LEVEL LOW OVER COLORADO WILL GRADUALLY MOVE
   SOUTHEASTWARD...BRINGING ADDITIONAL RAIN TO THE SOUTHERN ROCKIES AND
   TEXAS. A STATIONARY FRONT WILL STRETCH FROM NEW MEXICO...TO ALONG
   THE GULF COAST...TO THE SOUTHEAST STATES...AND WIDESPREAD PRECIP IS
   EXPECTED AGAIN ALONG THE BOUNDARY. ADDITIONALLY...A TROPICAL CYCLONE
   /CURRENTLY TROPICAL STORM FAY/ WILL MOVE TO OFF THE WEST COAST OF
   FLORIDA.
   
   ...ERN/CNTRL WA AND OR/NRN CA...
   THUNDERSTORMS CHANCES ARE MORE CERTAIN ON SUNDAY AS THE UPPER LEVEL
   STORM SYSTEM BEGINS TO MAKE AN IMPACT ON THE PACIFIC NORTHWEST.
   MODELS ARE IN FAIRLY GOOD AGREEMENT WITH A SHORTWAVE TROUGH MOVING
   THROUGH THE AREA ON SUNDAY AFTERNOON AND EVENING. ALSO...A JET MAX
   AROUND 50 KTS WILL MOVE ACROSS THE FORECAST REGION...AIDING LIFT AND
   THUNDERSTORM POTENTIAL. AS IN PREVIOUS DAYS...COVERAGE OF
   THUNDERSTORMS REMAINS FAIRLY UNCERTAIN SO A CRITICAL FIRE AREA WILL
   NOT BE FORECAST AT THIS TIME...BUT THE AREA MAY BE UPGRADED ON DAY 1
   IF THE THREAT CAN BE BETTER DEFINED.
