   VALID 261200Z - 271200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER-LEVEL TROUGH ALONG THE ERN SEABOARD WILL QUICKLY DAMPEN AS
   AN UPSTREAM WAVE OVER THE CANADIAN PRAIRIES UNDERGOES CONSIDERABLE
   AMPLIFICATION AND BECOMES CENTERED FROM THE GREAT LAKES TO THE
   MID-MS RIVER VALLEY. A STOUT MID-LEVEL ANTICYCLONE WILL REMAIN
   ANCHORED OVER THE DESERT SW...WITH A RIDGE AXIS SLOWLY BUILDING NWD
   ACROSS THE WRN CONUS.
   
   ...SRN CA...
   THE CONTINUED PRESENCE OF RIDGING ALOFT WILL HELP MAINTAIN
   SINGLE-DIGIT RH VALUES AND VERY WARM TEMPERATURES /MIDDLE 80S TO
   MIDDLE 90S/ OVER INLAND AREAS. WINDS WILL REMAIN VERY WEAK AND
   TERRAIN-DRIVEN.
   
   ...NRN FL...
   MODEST N/NWLY LOWER-LEVEL FLOW WILL LEND TO THE GRADUAL ADVECTION OF
   A DRIER CONTINENTAL AIR MASS INTO THE FL PENINSULA. AS TEMPERATURES
   WARM INTO THE MIDDLE 70S...RH VALUES SHOULD BECOME MARGINALLY LOW
   /AROUND 35 PERCENT/. SURFACE WINDS WILL BE WEAK /UNDER 10 MPH/.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0408 AM CDT SUN OCT 26 2008
   
   VALID 271200Z - 281200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   HIGHLY AMPLIFIED UPPER-LEVEL PATTERN WILL PERSIST INTO EARLY
   TUE...WITH A TROUGH OVER THE EAST AND A RIDGE IN THE WEST. A STRONG
   COLD FRONT STRETCHING ALONG THE EAST COAST TO THE GULF COAST AT THE
   ONSET OF THE PERIOD WILL PUSH RAPIDLY S/EWD THROUGH THE GULF OF
   MEXICO AND WRN ATLANTIC. AN EXPANSIVE ANTICYCLONE WILL BUILD SWD
   ACROSS THE PLAINS.
   
   ...S-CNTRL TX...
   IN THE WAKE OF A COLD FRONT PASSAGE MON MORNING...STRONG LOW-LEVEL
   N/NELYS AND A TIGHT SURFACE PRESSURE GRADIENT SHOULD LEAD TO GUSTY
   WINDS AMIDST A RAPIDLY DRYING AIR MASS. SUSTAINED SURFACE WINDS OF
   20 TO 25 MPH SHOULD BECOME JUXTAPOSED WITH RH VALUES FALLING TO
   BETWEEN 15 AND 20 PERCENT NEAR NOON. HOWEVER...MODEL FORECASTS
   INDICATE SUBSTANTIAL WEAKENING OF THE PRESSURE GRADIENT AND
   SUBSEQUENT MASS RESPONSE IN THE AFTERNOON AS AN ANTICYCLONE QUICKLY
   APPROACHES. THUS...UNCERTAINTY OVER THE OVERALL DURATION OF CRITICAL
   CONDITIONS WILL PRECLUDE AN AREAL DELINEATION ATTM.
   
   ...NRN FL...
   A PERIOD OF GUSTY NWLYS APPEARS PROBABLE MON AFTERNOON AFTER A COLD
   FRONT PASSAGE...WITH RH VALUES DIPPING BELOW 35 PERCENT. THIS SHOULD
   RESULT IN A SHORT DURATION CRITICAL THREAT PRIOR TO STRENGTHENING
   CAA AND THE LOSS OF DAYTIME HEATING. LONGER DURATIONS OF LOW RH WILL
   BE PREVALENT ACROSS THE FL PANHANDLE...SRN GA AND SRN AL.
   HOWEVER...RECENT MODERATE TO HEAVY RAINFALL IN THESE AREAS SUGGEST
   OVERALL FIRE POTENTIAL SHOULD BE TEMPERED.
   
   ...PORTIONS OF SERN AZ...
   GUSTY ELY WINDS WILL DEVELOP MON MORNING AS A COLD FRONT SURGES WWD
   TOWARDS THE SW DESERTS. A COOLER AND MORE MOIST BOUNDARY LAYER WILL
   LIKELY LIMIT CRITICALLY LOW RH FROM DEVELOPING OVER MOST OF THE
   AREA. HOWEVER...DOWNSLOPE EFFECTS SHOULD RESULT IN LOCALIZED RH
   VALUES NEAR 15 PERCENT IMMEDIATELY DOWNSTREAM OF VARIOUS MTN CHAINS.
