VALID 121200Z - 171200Z
...DISCUSSION...
UPPER TROUGHING IS EXPECTED TO EXTEND FROM THE SWRN U.S. INTO THE
UPPER GREAT LAKES REGION INTO EARLY NEXT WEEK WITH A BELT OF FAIRLY
STRONG FLOW ALOFT FROM NRN MEXICO INTO THE OH VALLEY. THIS FLOW
REGIME WILL FORCE A COLD FRONT ACROSS ERN TX INTO THE LOWER MS
VALLEY/CNTRL GULF STATES WHERE ASCENT ATOP FRONTAL ZONE SHOULD
ENCOURAGE CONVECTIVE DEVELOPMENT. WHILE STRONG FLOW ALOFT WILL BE
NOTED ALONG THE ADVANCING WIND SHIFT...SEEMINGLY SUPPORTIVE OF
ORGANIZED SEVERE TSTMS...WEAK THERMODYNAMIC PROFILES AND THE
TENDENCY FOR POST-FRONTAL CONVECTION MAY ULTIMATELY LIMIT SEVERE
POTENTIAL WITH THIS ACTIVITY DURING THE DAY4-5 TIME FRAME.
