...DISCUSSION...

IN THE ABSENCE OF MEANINGFUL MOISTURE/INSTABILITY...THE LIKELIHOOD
FOR ORGANIZED SEVERE THUNDERSTORMS WILL REMAIN RATHER LOW DURING THE
EXTENDED PERIOD. BOTH THE GFS AND ECMWF MAINTAIN E-W SFC
ANTICYCLONE ALONG THE GULF COAST...EFFICIENTLY PREVENTING THE RETURN
OF MARITIME TROPICAL AIR INLAND. WHILE SEVERAL NOTEWORTHY SHORTWAVE
TROUGHS WILL MIGRATE ACROSS THE U.S. DURING THE PERIOD...A WOEFUL
LACK OF MOISTURE/INSTABILITY WILL PREVENT AN OUTLOOK OF SEVERE THIS
PERIOD.
