...DISCUSSION...
06/00Z MEDIUM-RANGE GUIDANCE IS IN GENERALLY GOOD AGREEMENT IN THE
EVOLUTION OF THE LARGE-SCALE PATTERN THROUGH THE EXTENDED PERIOD.
SOME POTENTIAL FOR SEVERE WEATHER WILL EXIST ALONG THE MIDDLE AND
SERN ATLANTIC COAST ON D4 /WED DEC 9TH/ IN CONJUNCTION WITH STRONG
SHORT WAVE TROUGH AND ATTENDANT COLD FRONT PROGRESSING THROUGH THE
ERN CONUS. CURRENTLY...THIS THREAT APPEARS TOO MARGINAL TO WARRANT
INCLUSION OF A REGIONAL AREA.
THEREAFTER...LARGE-SCALE PATTERN GRADUALLY DE-AMPLIFIES WITH A BELT
OF MODERATELY STRONG QUASI-ZONAL FLOW MAINTAINED ACROSS THE SRN
STATES. PERSISTENT SURFACE RIDGING E OF THE MS RIVER IS EXPECTED TO
SUPPRESS A MOIST AND UNSTABLE AIR MASS TO THE GULF OF MEXICO. AS
SUCH...ANY PROSPECT FOR ORGANIZED SEVERE WEATHER APPEARS QUITE LOW
ATTM.
