   ...SYNOPSIS/FORECAST...
   ZONAL FLOW IS EXPECTED TO DEVELOP ACROSS THE CONUS ON DAY 2 AS A
   PACIFIC TROUGH DIGS SWD INTO THE NWRN STATES...RESULTING IN FURTHER
   RETROGRESSION OF THE WRN RIDGE TOWARD THE ERN PACIFIC WHILE THE ERN
   U.S. LONG WAVE TROUGH MOVES EWD OFFSHORE.  THIS PATTERN CHANGE
   COMBINED WITH A SHORT WAVE TROUGH TRACKING FROM THE ERN GREAT BASIN/
   FOUR CORNERS REGION TO THE SRN PLAINS MONDAY WILL INDUCE A LOW-LEVEL
   TROUGH IN LEE OF THE ROCKIES.  OFFSHORE/NLY LOW-LEVEL WINDS ARE
   EXPECTED TO PREVAIL FOR MUCH OF THIS FORECAST PERIOD OVER THE
   GULF...WITH SLY FLOW DEVELOPING ACROSS THE WRN/NWRN GULF REGION LATE
   IN THE PERIOD AS A SURFACE HIGH SHIFTS EWD TOWARD FL.  HOWEVER...THE
   RECENT INTRUSION OF A CP AIR MASS ACROSS MUCH OF THE GULF BASIN
   SHOULD REQUIRE SEVERAL DAYS OF MODIFICATION BEFORE SUFFICIENT NWD
   MOISTURE RETURN WOULD SUPPORT THUNDERSTORM DEVELOPMENT. 
   
   THUS...A COLD/STABLE AIR MASS ACROSS THE LOWER 48 STATES WILL
   PRECLUDE THE THREAT OF THUNDERSTORMS THROUGH THE FORECAST PERIOD.
