DAY 4-8 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK

VALID 131200Z - 181200Z

...DISCUSSION...

10/00Z MEDIUM-RANGE GUIDANCE REMAINS IN GENERALLY GOOD AGREEMENT IN
THE EVOLUTION OF THE LARGE-SCALE PATTERN THROUGH THE PERIOD. AS
MENTIONED IN PREVIOUS EXTENDED DISCUSSION...A LOWER LATITUDE SHORT
WAVE TROUGH AND ASSOCIATED COLD FRONT WILL AFFECT THE GULF COAST
STATES ON D5 AND D6 / MON DEC 14TH AND TUE DEC 15TH/. AS IS STILL
THE CASE...TSTMS APPEAR LIKELY WITH THIS SYSTEM...NAMELY ALONG THE
COAST. BUT...THE PROSPECT FOR ORGANIZED SEVERE WEATHER
APPEARS LOW.

THEREAFTER...HIGH PRESSURE BUILDS SWD INTO THE GULF OF MEXICO WITH
NO APPRECIABLE TSTM POTENTIAL.
