...SYNOPSIS...
BROAD FETCH OF WSWLY TO SWLY FLOW ALOFT EXTENDS FROM PACIFIC
OFFSHORE SRN CA..TO MID ATLANTIC AND NEW ENGLAND...INTERRUPTED ONLY
BY SHORTWAVE TROUGH NOW MOVING NEWD ACROSS OZARK PLATEAU.  EXPECT
THAT TROUGH TO DEAMPLIFY AND ACCELERATE...EJECTING NEWD ACROSS MUCH
OF GREAT LAKES AND OH VALLEY BY END OF PERIOD. AT SFC...COLD FRONT
WITH WEAK LOWS OVER CENTRAL/NRN MS IS FCST TO MOVE SLOWLY SEWD
ACROSS MORE OF MS...SRN LA AND AL DURING REMAINDER PERIOD...WHILE
SFC LOW MOVES NEWD ACROSS KY AND BECOMES BETTER DEFINED.

FARTHER W...SHORTWAVE TROUGH HAS MOVED INLAND ACROSS CA AND WILL
CONTINUE DEAMPLIFYING TONIGHT OVER GREAT BASIN AND CENTRAL ROCKIES. 
MEANWHILE...EXPECT DEEP-LAYER CYCLONE CENTERED JUST OFFSHORE WA TO
DRIFT ERRATICALLY THROUGH 06-09Z PERIOD THEN TURN NEWD TOWARD CAPE
FLATTERY AND VANCOUVER ISLAND BY 12Z.

...MS DELTA TO TN VALLEY...
BAND OF CLOUDS/PRECIP AND BROKEN LINE OF EMBEDDED TSTMS IS EVIDENT
ATTM FROM S-CENTRAL LA NEWD TO N-CENTRAL/NWRN AL.  THIS ACTIVITY
SHOULD SHIFT EWD ACROSS MS/AL AND SERN LA THIS EVENING AND
TONIGHT...WITH EMBEDDED THUNDER GRADUALLY DIMINISHING IN OVERALL
COVERAGE.  EXPECT REMAINING INSTABILITY TO WEAKEN GRADUALLY THROUGH
TONIGHT...WITH ELEVATED MUCAPE DECREASING TO LESS THAN 500 J/KG OVER
SERN LA AND COASTAL MS...AND AOB 200 J/KG FARTHER INLAND.  LARGE
SCALE SINKING MOTION -- EVIDENT ON MOISTURE CHANNEL IMAGERY OVER E
TX...SRN OK AND SWRN AR...WILL IMPINGE ON REGION FROM W AS SHORTWAVE
TROUGH EJECTS AWAY FROM REGION.  THEREFORE EXPECT CONVECTIVE
POTENTIAL TO DIMINISH FROM W-E AND WITH TIME.

...W COAST...
TSTM POTENTIAL HAS DIMINISHED SIGNIFICANTLY OVER COASTAL CENTRAL/SRN
CA WITH INLAND PASSAGE AND WEAKENING OF SHORTWAVE TROUGH...AND
RESULTANT HEIGHT RISES.  A FEW CG LIGHTING STRIKES HAVE BEEN
DETECTED WELL OFFSHORE ORE COAST...IN REGION OF SHALLOW/COLD-CORE CB
ASSOCIATED WITH MID/UPPER LOW. EPISODIC LIGHTNING IS POSSIBLE IN
IMMEDIATE VICINITY OF WA/ORE COAST AS PERIPHERY OF SOME OF THE COLD
AIR ALOFT ASSOCIATED WITH OFFSHORE LOW MOVES OVERHEAD...STEEPENING
LAPSE RATES.
