   DAY 1 FIRE WEATHER OUTLOOK

   1003 AM CST THU NOV 27 2014

   VALID 271700Z - 281200Z

   ...NO CRITICAL AREAS...

   NO CHANGES TO PREVIOUS FORECAST. BEST POTENTIAL FOR LOCALLY ELEVATED
   CONDITIONS ACROSS THE SERN CONUS WILL EXIST IN SRN FL...PRIMARILY SE
   OF LAKE OKEECHOBEE. HIGH TEMPERATURES SHOULD BE IN THE LOWER-MID
   70S...WHICH COMBINED WITH THE DRY POST-FRONTAL AIR MASS...WILL
   RESULT IN RH VALUES NEAR 30-35 PERCENT. WHILE MOST OF FL HAS
   EXPERIENCED CONSIDERABLE WETTING RAINS RECENTLY...THIS PORTION OF FL
   HAS GENERALLY EXPERIENCED BELOW-NORMAL RAINFALL OVER THE LAST 7-14
   DAYS. HOWEVER...ONLY LOCALIZED ELEVATED CONDITIONS ARE FORECAST...AS
   THE COMBINATION OF LOW RH AND MARGINAL SUSTAINED WIND VALUES SHOULD
   BE BRIEF/SPOTTY. AS SUCH...NO DELINEATION WILL BE INTRODUCED.

   .PREV DISCUSSION... /ISSUED 0219 AM CST THU NOV 27 2014/

   ...SYNOPSIS...
   UPPER LEVEL PATTERN WILL TREND MORE ZONAL AS A SHORTWAVE TROUGH
   MOVES THROUGH THE NORTHEAST STATES AND WRN CONUS RIDGING
   DEAMPLIFIES. AT THE SURFACE...HIGH PRESSURE WILL TRANSLATE SEWD
   ACROSS THE MS VALLEY AND INTO THE TN VALLEY/SOUTHEAST STATES WHILE
   LEE TROUGHING EXPANDS OVER THE HIGH PLAINS. 
    
   TEMPERATURES IN THE LOW 80S AND RH VALUES BELOW 15 PERCENT WILL
   RESULT IN SOME LOCALLY ELEVATED FIRE WEATHER CONDITIONS ACROSS SRN
   CA BUT WEAK WINDS WILL TEMPER A GREATER THREAT. SOME LOCALLY
   ELEVATED CONDITIONS ARE ALSO EXPECTED ACROSS SRN AL/GA AND FL AS A
   POST-FRONTAL REGIME USHERS IN A VERY DRY AIRMASS -- PW VALUES AROUND
   0.20 INCH...WHICH IS AROUND THE 10TH PERCENTILE -- AND WINDS
   APPROACH 15 MPH. 

   ...SRN HIGH PLAINS...
   HIGH PLAINS LEE TROUGHING WILL INCREASE THE SURFACE PRESSURE
   GRADIENT ENOUGH TO SUPPORT SUSTAINED SWLY WINDS AROUND 15 TO 20 MPH
   THROUGHOUT THE SRN HIGH PLAINS. TEMPERATURES WILL CLIMB INTO THE MID
   60S WITH MIN RH VALUES LIKELY FROM 15 TO 20 PERCENT. GENERALLY
   MARGINAL CONDITIONS COMBINED WITH MOIST FUELS WILL MITIGATE MUCH OF
   THE FIRE WEATHER THREAT ALTHOUGH SOME LOCALLY ELEVATED CONDITIONS
   ARE POSSIBLE.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   1151 AM CST THU NOV 27 2014

   VALID 281200Z - 291200Z

   ...NO CRITICAL AREAS...

   INCREASING W/SW MID-LEVEL FLOW ACROSS THE WEST COAST WILL WORK IN
   TANDEM WITH CONTINUED DRY AND WARM SFC CONDITIONS ACROSS THE
   MOUNTAINS AND INTERIOR VALLEYS OF SRN CA TO PRODUCE SPOTTY ELEVATED
   FIRE WX CONDITIONS TOMORROW. LOW RH VALUES WILL BE COMMON ACROSS
   THESE AREAS...BUT SUSTAINED WINDS WILL BE MARGINAL...KEEPING ANY
   CONSIDERABLE FIRE WX CONCERNS CONFINED TO LOCALIZED TERRAIN-FAVORED
   AREAS.

   ...SRN HIGH PLAINS...
   NO CHANGES TO PREVIOUS FORECAST.

   ..PICCA.. 11/27/2014

   .PREV DISCUSSION... /ISSUED 0220 AM CST THU NOV 27 2014/

   ...SYNOPSIS...
   ZONAL FLOW WILL PERSIST THROUGHOUT THE PERIOD. PRIMARY UPPER FEATURE
   WILL BE A SHORTWAVE TROUGH APPROACHING THE PACIFIC NW FROM BRITISH
   COLUMBIA LATE IN THE PERIOD. AT THE SURFACE...HIGH PRESSURE WILL
   GRADUALLY SHIFT EWD FROM THE SOUTHEAST STATES/TN VALLEY TO THE
   MID-ATLANTIC WHILE PRESSURES GRADUALLY LOWER WITHIN THE TROUGH
   ACROSS THE PLAINS.

   ...SRN HIGH PLAINS...
   DEEPENING PLAINS TROUGH WILL HELP INCREASE THE SURFACE PRESSURE
   GRADIENT OVER THE REGION. AS A RESULT...WIND SPEEDS ARE EXPECTED TO
   BE A FEW MPH HIGHER THAN ON THURSDAY WITH SUSTAINED SPEEDS AROUND 20
   MPH LIKELY. TEMPERATURES ARE ALSO EXPECTED TO BE 7 TO 10 DEGREES
   WARMER WITH HIGHS GENERALLY IN THE MID 70S -- NEAR RECORD HIGHS
   ACROSS THE TX PANHANDLE -- AND RH VALUES IN THE TEENS. THESE
   METEOROLOGICAL CONDITIONS ARE CONSISTENT WITH ANY ELEVATED FIRE
   WEATHER THREAT IN AREAS WHERE FUELS ARE DRY.
