   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0220 AM CDT WED MAY 14 2008
   
   VALID 141200Z - 151200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF NRN CA......
   ...CRITICAL FIRE WEATHER AREA FOR FAR WRN TX......
   
   ...SYNOPSIS...
   IN THE EAST...AN UPPER TROUGH WILL SWEEP THROUGH THE GREAT LAKES
   REGION WITH A SURFACE LOW LOCATED ROUGHLY OVER QUEBEC AND A COLD
   FRONT EXTENDING THROUGH MUCH OF THE APPALACHIANS...SOUTHWESTWARD
   INTO ERN TX. DRY CONDITIONS WILL CONTINUE IN NEW ENGLAND AHEAD OF
   THE FRONT WHERE MOISTURE INCREASE WILL BE LESS SPARSE.
   
   HIGH PRESSURE WILL DOMINATE IN THE SOUTHEASTERN STATES
   AHEAD OF A SECOND UPPER LOW...ROUGHLY LOCATED OVER SRN NM THAT WILL
   LIFT ENEWD THROUGH THURSDAY MORNING. IN FLORIDA...ONSHORE FLOW WILL
   SLOWLY ALLOW RELATIVE HUMIDITIES TO RECOVER ALONG THE EAST
   COAST...ALTHOUGH LOW RELATIVE HUMIDITIES WILL AFFECT INLAND AREAS
   ONCE AGAIN.
   
   IN THE WEST...HIGHLY AMPLIFIED UPPER HIGH PRESSURE WILL BUILD INTO
   THE WEST COAST...WITH ABOVE NORMAL TEMPERATURES AND WINDY CONDITIONS
   AFFECTING PORTIONS OF NORTHERN CALIFORNIA.
   
   ...CRITICAL FIRE WEATHER AREA - PORTIONS OF NRN CA......
   
   PRIMARY CONDITIONS: STRONG WINDS...LOW RH...UNSEASONABLY WARM
   TEMPERATURES
   
   STRONGLY AMPLIFIED UPPER HIGH PRESSURE LOCATED OVER THE ERN PACIFIC
   WILL SHIFT EWD TODAY...BECOMING CENTERED JUST OFFSHORE OF THE OR/CA
   COASTS. STRONG SUBSIDENCE ACROSS CALIFORNIA WILL LEAD TO ABOVE
   NORMAL TEMPERATURES...WITH THE LOWER VALLEYS EXPECTED TO WARM INTO
   THE 90S...WHILE A DRY NORTHERLY FLOW WILL LEAD TO RELATIVE
   HUMIDITIES DROPPING INTO THE TEENS AND LOWER 20S. STRONG WINDS
   AROUND THE PERIPHERY OF THE HIGH...BOTH IN LOW LEVELS AND UPPER
   LEVELS...WILL LEAD TO SUSTAINED SURFACE SPEEDS FROM 15 TO 30
   MPH...WITH THE HIGHEST GUSTS IN THE AFTERNOON AS STRONG HEATING AND
   NEAR DRY ADIABATIC PROFILES ALLOW STRONGER LOW LEVEL WINDS TO MIX TO
   THE SURFACE. IN TALKING WITH THE LOCAL OFFICES...FUELS BELOW 3000
   FEET ARE CURED...WHICH WILL CREATE ENHANCED FIRE DANGER FOR TODAY.
   BY LATE EVENING AS HIGH PRESSURE SHIFTS EWD OVER THE PACIFIC
   NORTHWEST...WINDS WILL SHIFT TO A MORE NORTHEASTERLY THEN EASTERLY
   DIRECTION...REDUCING WIND SPEEDS THROUGH THE SACRAMENTO AND SAN
   JOAQUIN VALLEYS...ALTHOUGH RELATIVE HUMIDITIES WILL NOT RECOVER MUCH
   OVERNIGHT.
   
   ...CRITICAL FIRE WEATHER AREA - FAR WRN TX......
   
   PRIMARY CONDITIONS: STRONG WINDS...LOW RH...DROUGHT
   
   THE NEARLY STATIONARY UPPER LOW LOCATED ROUGHLY OVER SRN NM WILL
   FINALLY BEGIN TO SHIFT ENEWD TODAY AND BECOME AN OPEN WAVE OVER
   TX/OK BY MORNING. AS THIS OCCURS...A JET AXIS AROUND THE BASE OF THE
   LOW WILL KEEP STRONG WLY TO WSWLY WINDS OVER FAR WRN TX...WITH
   SUSTAINED SPEEDS NEAR 20 TO 30 MPH WITH HIGHER GUSTS. A WIND SHIFT
   FROM WLY TO NLY CAN BE EXPECTED BY LATE EVENING AND THROUGH EARLY
   MORNING. RELATIVE HUMIDITIES IN THE TEENS DURING THE AFTERNOON WILL
   BEGIN TO RECOVER SOMEWHAT AS THIS WIND SHIFT OCCURS.
   ADDITIONALLY...EARLY IN THE PERIOD DRY THUNDERSTORMS MAY BE POSSIBLE
   ALONG THE DRY LINE BEFORE THE SYSTEM PROGRESSES ENEWD.
   
   ...FLORIDA...
   SURFACE HIGH PRESSURE IS FORECAST TO SHIFT EWD AND BECOME CENTERED
   OFFSHORE OF THE CAROLINAS. THIS WILL ALLOW FOR ANOTHER DAY OF
   ONSHORE FLOW ALONG THE EAST COAST OF THE PENINSULA...HELPING TO KEEP
   RELATIVE HUMIDITIES ABOVE CRITICAL THRESHOLDS NEAR THE COAST.
   HOWEVER...INLAND LOCATIONS MAY EXPERIENCE EXTENDED DURATIONS OF
   RELATIVE HUMIDITIES BELOW 35 PERCENT. ADDITIONALLY NEAR THE
   COAST...SEA BREEZE DEVELOPMENT IS EXPECTED AGAIN TODAY...WHICH MAY
   LEAD TO WINDS NEAR 15 MPH CLOSER TO THE ONGOING FIRES.
   
   ...NEW ENGLAND...
   RELATIVE HUMIDITIES RANGING FROM 25 TO 30 PERCENT CAN BE EXPECTED IN
   THE AFTERNOON AS TEMPERATURES WARM INTO THE 70S IN A SOUTHERLY FLOW.
   WINDS WILL GENERALLY REMAIN NEAR 5 TO 10 MPH...ALTHOUGH GUSTS OF 15
   TO 20 MPH MAY BE POSSIBLE IN THE AFTERNOON.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0245 AM CDT WED MAY 14 2008
   
   VALID 151200Z - 161200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR SRN NV...SWRN UT...SRN CA...WRN
   AZ......
   
   ...SYNOPSIS...
   IN THE EAST...A NRN STREAM UPPER TROUGH WILL MERGE WITH A DEVELOPING
   LOW IN THE SWRN STATES...BECOMING A LONG WAVE TROUGH AXIS EXTENDING
   FROM NERN ONTARIO ROUGHLY THROUGH BAJA CALIFORNIA. IN THE
   SOUTHEAST...HIGH PRESSURE WILL GRADUALLY BREAK DOWN...ALLOWING AN
   INCREASE IN MOISTURE.
   
   MEANWHILE IN THE WEST...UPPER HIGH PRESSURE WILL CONTINUE TO
   AMPLIFY...LEADING TO ABOVE NORMAL TEMPERATURES NEAR THE WEST COAST.
   STRONG WINDS AROUND THE PERIPHERY OF THE HIGH AND THE DEVELOPING LOW
   PRESSURE IN THE SWRN STATES WILL LEAD TO STRONG WINDS AND CRITICAL
   FIRE WEATHER CONDITIONS ACROSS SRN NV...SWRN UT...SRN CA...AND WRN
   AZ...ESPECIALLY NEAR THE LOWER CO RIVER VALLEY.
   
   ...CRITICAL FIRE WEATHER AREA - SRN NV...SWRN UT...SRN CA...WRN
   AZ...
   
   PRIMARY CONDITIONS: STRONG WINDS...LOW RH...DROUGHT...
   
   A STRONG NLY TO NELY JET AXIS WILL DEVELOP BETWEEN AMPLIFYING UPPER
   HIGH PRESSURE THAT WILL BUILD ALONG THE WEST COAST...AND A
   DEVELOPING AREA OF LOW PRESSURE LOCATED ROUGHLY INVOF NM. THIS WILL
   ALLOW SURFACE WIND SPEEDS NEAR 20 TO 30 MPH...WITH HIGHER SPEEDS
   THROUGH THE LOWER COLORADO RIVER VALLEY WHERE CHANNELING WILL ALLOW
   AN INCREASE IN SPEEDS. DEEP MIXING WILL ALLOW JET WINDS TO MIX TO
   THE SURFACE...WITH STRONG GUSTS LIKELY IN THE AFTERNOON. AS
   TEMPERATURES WARM INTO THE LOWER TO UPPER 90S ACROSS THE LOWER
   VALLEYS...RELATIVE HUMIDITIES WILL DROP INTO THE SINGLE DIGITS AND
   LOWER TEENS.
