...NO TSTM AREAS FORECAST...

...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.
