   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0146 AM CST MON NOV 16 2009
   
   VALID 161200Z - 171200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER LOW IN THE CNTRL/SRN PLAINS WILL SLOWLY DRIFT
   EWD...BECOMING ORIENTED ROUGHLY NEAR THE MO/AR BORDER BY TUESDAY
   MORNING. MEANWHILE...UPPER RIDGING IN THE WEST IS SLOWLY BEGINNING
   TO DEAMPLIFY AND SHIFT EWD AHEAD OF A STRONG UPPER TROUGH THAT WILL
   SHIFT ONSHORE IN THE PACIFIC NORTHWEST THROUGH THE PERIOD. AS THIS
   OCCURS...THE SURFACE HIGH THAT HAS BEEN DOMINANT OVER THE PACIFIC
   NORTHWEST WILL WEAKEN AND SHIFT EWD...RESULTING IN THE CESSATION OF
   THE OFFSHORE EVENT IN SRN CA.
   
   ...COASTAL SRN CA...
   00Z SAN DIEGO SOUNDING AND 06Z SURFACE ANALYSIS REFLECTS A DRY
   AIRMASS ALONG THE SRN CA COAST. ANOTHER DAY OF CRITICALLY LOW
   RELATIVE HUMIDITIES CAN BE ANTICIPATED AS DOWNSLOPE FLOW/DIURNAL
   HEATING CONTRIBUTE TO VALUES IN THE TEENS AND SINGLE DIGITS.
   HOWEVER...06Z SURFACE ANALYSIS SHOWS ONLY A WEAK PRESSURE GRADIENT
   OVER THE AREA...AND FURTHER WEAKENING IS EXPECTED THROUGH THE DAY AS
   AN UPPER TROUGH BEGINS TO MOVE ONSHORE IN THE PACIFIC NORTHWEST.
   ISOLATED GUSTS TO 40 MAY BE POSSIBLE IN FAVORABLY ORIENTED
   TERRAIN...BUT OVERALL PATTERN DOES NOT FAVOR A CRITICAL OUTLINE AT
   THIS TIME.
