   ..DARROW.. 03/06/2015

   .PREV DISCUSSION... /ISSUED 1013 AM CST FRI MAR 06 2015/

   ...SYNOPSIS...
   THE INFLUENCE OF A PERSISTENT ERN CONUS TROUGH IS REFLECTED IN A
   CONTINENTAL POLAR AIR MASS AND OFFSHORE FLOW ACROSS THE ATLANTIC AND
   GULF COASTS.  THE ASSOCIATED COLD FRONT IS DRIFTING SWD NEAR LAKE
   OKEECHOBEE IN S FL.  BOUNDARY LAYER DEWPOINTS IN THE 68-70 F RANGE
   ALONG AND S OF THE FRONT WILL CONTRIBUTE TO BUOYANCY WITH DAYTIME
   HEATING ACROSS S FL.  HOWEVER...12Z SOUNDINGS REVEALED RELATIVELY
   WARM TEMPERATURES AND POOR LAPSE RATES ALOFT...SUCH THAT ANY
   BUOYANCY SHOULD BE CONFINED TO THE LOW LEVELS...WITH WARM-PROCESS
   SHOWERS AND NO LIGHTNING THE LIKELY OUTCOME.

   OTHERWISE...THE REX BLOCK PATTERN WILL CONTINUE OVER THE PAC
   COAST...WITH THE RELATED CLOSED LOW OVER NRN BAJA.  A LACK OF
   LOW-MIDLEVEL MOISTURE WILL PRECLUDE THE RISK FOR THUNDERSTORMS WITH
   THIS SYSTEM THROUGH EARLY SATURDAY.
