...NO TSTM AREAS FORECAST...

...SYNOPSIS...
THE PATTERN OVER THE CONUS HAS EVOLVED TO AN AMPLIFIED RIDGE OVER
THE GREAT BASIN AND A TROUGH OVER THE MS VALLEY REGION...AND THIS
FLOW REGIME WILL PERSIST WITH GRADUAL EWD PROGRESSION THROUGH
TOMORROW.  CYCLOGENESIS IS EXPECTED NEAR OR JUST OFF THE NC COAST BY
EARLY FRIDAY IN ASSOCIATION WITH AN EMBEDDED SHORTWAVE TROUGH THAT
IS DIGGING ESEWD OVER THE LOWER MS VALLEY.  SOME CONVECTION MAY
DEVELOP BY EARLY FRIDAY OVER THE GULF STREAM...BUT THUNDERSTORMS ARE
NOT EXPECTED INLAND.  ELSEWHERE...A SHORTWAVE TROUGH CENTERED NEAR
38 N AND 137 W WILL MOVE NEWD TOWARD THE WA/BRITISH COLUMBIA COASTS
BY LATE TONIGHT.  OCEANIC LIGHTNING DATA AND SATELLITE IMAGERY SHOW
A FEW THUNDERSTORMS WITH THE MID LEVEL COLD CORE AND IN THE
BAROCLINIC BAND APPROACHING 130 W.  HOWEVER...THIS SYSTEM WILL TEND
TO LOSE AMPLITUDE WHILE ENCOUNTERING THE RIDGE JUST INLAND FROM THE
PAC COAST...AND THE THREAT FOR DEEP CONVECTION SHOULD REMAIN
OFFSHORE THIS PERIOD.
