   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   1127 AM CDT FRI APR 18 2014

   VALID 181700Z - 191200Z

   ...NO CRITICAL AREAS...

   THE ONLY CHANGE THIS FORECAST UPDATE IS TO REMOVE THE ISOLATED DRY
   THUNDERSTORM AREA OVER THE FOUR CORNERS.  THE LATEST MODEL GUIDANCE
   SUGGESTS COVERAGE OF THUNDERSTORMS WILL REMAIN SPARSE.  SUBSTANTIAL
   MID TO HIGH-LEVEL CLOUD COVER WILL PROBABLY TEMPER VERY DEEP
   BOUNDARY LAYER MIXING AND THE FORMATION OF A VERY DRY/DEEP SUB-CLOUD
   LAYER.  DESPITE THESE METEOROLOGICAL CONDITIONS AND FUELS ONLY NOW
   BEGINNING THEIR EARLY SEASON RESPONSIVENESS...A BRIEF/LOW THREAT FOR
   LIGHTNING GENERATED FIRES MAY EXIST BUT THE THREAT DOES NOT APPEAR
   TO WARRANT A GRAPHICAL THREAT AREA.

   ..SMITH.. 04/18/2014

   .PREV DISCUSSION... /ISSUED 0217 AM CDT FRI APR 18 2014/

   ...SYNOPSIS...
   A SRN STREAM UPPER LOW APPROACHING THE SRN CA COAST WILL SLOWLY MOVE
   EWD...WITH A PLUME OF MIDLEVEL MOISTURE OVERSPREADING THE SOUTHWEST
   AND SRN ROCKIES. NRN STREAM WILL REMAIN MORE ACTIVE AS A SERIES OF
   PROGRESSIVE SHORTWAVE TROUGHS MOVE ACROSS THE NRN ROCKIES AND UPPER
   GREAT LAKES. AT THE SFC...SLY FLOW WILL DEVELOP ACROSS THE PLAINS ON
   THE WRN PERIPHERY OF HIGH PRESSURE CENTERED NEAR THE MS VALLEY...AND
   LOW PRESSURE WILL DEEPEN ACROSS THE DAKOTAS.

   ...FOUR CORNERS AREA...
   MODEST MIDLEVEL MOISTENING AHEAD OF THE AFOREMENTIONED PACIFIC LOW
   WILL CONTRIBUTE TO PW VALUES INCREASING TO AROUND 0.4-0.5 INCH.
   STRONG SFC HEATING WILL ALLOW MARGINAL DESTABILIZATION TO
   OCCUR...SUPPORTING THE DEVELOPMENT OF A FEW AFTERNOON/EVENING TSTMS.
   THE BOUNDARY-LAYER WILL REMAIN QUITE DRY...SO ANY TSTMS THAT DEVELOP
   WILL LIKELY PRODUCE LITTLE TO NO PRECIPITATION. TSTM COVERAGE IS
   FORECAST TO REMAIN TOO SPARSE TO WARRANT A CRITICAL DRY TSTM RISK.
