...NO TSTM AREAS FORECAST...

...SUMMARY...
THUNDERSTORMS ARE NOT EXPECTED ACROSS THE CONTIGUOUS UNITED STATES
THROUGH TONIGHT.

...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.
