   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0355 AM CDT SUN APR 26 2015

   VALID 261200Z - 271200Z

   ...SYNOPSIS...
   A HIGHLY AMPLIFIED UPPER PATTERN WILL BE IN PLACE TODAY...WITH A
   DEEP UPPER TROUGH CURRENTLY OVER THE INTERMOUNTAIN WEST EXPECTED TO
   CLOSE OFF INTO AN UPPER LOW OVER THE SRN HIGH PLAINS...WHILE AN
   UPPER RIDGE BUILDS INTO THE PACIFIC COAST. AT THE SURFACE...HIGH
   PRESSURE WILL BEGIN TO BUILD INTO THE GREAT BASIN...RESULTING IN A
   PERIOD OF OFFSHORE FLOW ACROSS SRN CA BEGINNING TONIGHT.
   MEANWHILE...STRONG LOW-LEVEL WLY FLOW WILL DEVELOP ACROSS SERN NM/W
   TX AHEAD OF THE UPPER TROUGH AND SOUTH OF A COLD FRONT THAT WILL BE
   DRAPED ACROSS THE SRN HIGH PLAINS.

   ...PORTIONS OF WRN TX AND ERN NM...
   ELEVATED TO LOCALLY CRITICAL METEOROLOGICAL CONDITIONS WILL DEVELOP
   ACROSS PARTS OF ERN NM/W TX THIS AFTERNOON...WITH SUSTAINED WLY
   WINDS OF 15-30 MPH EXPECTED WHILE RH DROPS INTO THE 10-20 PERCENT
   RANGE. THERE IS LIKELY TO BE SOME DISPLACEMENT BETWEEN THE AREA OF
   STRONGEST WINDS ACROSS ERN NM INTO THE TX TRANS-PECOS REGION...AND
   THE AREA OF WARMEST TEMPS/LOWEST RH IMMEDIATELY BEHIND THE DRYLINE
   ACROSS W TX. GIVEN THIS DISPLACEMENT AND SOME ANTECEDENT
   RAINFALL/GREENUP ACROSS PARTS OF THE AREA...NO CRITICAL DELINEATION
   WILL BE MADE AT THIS TIME.

   ...LOWER CO RIVER VALLEY...
   LOCALLY ELEVATED CONDITIONS ARE POSSIBLE ACROSS THE LOWER CO RIVER
   VALLEY...AS NWLY SFC WINDS OF 15-20 WILL DEVELOP THIS AFTERNOON IN
   CONJUNCTION WITH MINIMUM RH VALUES OF 10-20 PERCENT. CRITICAL
   WIND/RH MAY BE REALIZED IN LOCALIZED AREAS...BUT MARGINAL WIND
   SPEEDS AND SOME RECENT RAINFALL/FUEL MOISTENING SHOULD LIMIT THE
   OVERALL THREAT.

   ...SRN CA COASTAL RANGES AND ADJACENT FOOTHILLS...
   OFFSHORE FLOW WILL DEVELOP LATE TONIGHT INTO MONDAY MORNING ACROSS
   SRN CA...AS HIGH PRESSURE BUILDS INTO THE GREAT BASIN. COASTAL
   RANGES AND ADJACENT FOOTHILLS WILL LIKELY SEE THE STRONGEST
   WINDS...BUT MARGINAL RH AND FUEL CONDITIONS SHOULD LIMIT THE OVERALL
   THREAT THROUGH THE END OF THE DAY1 PERIOD.
