0343 AM CDT MON OCT 29 2007
VALID 011200Z - 061200Z
..SEVERE POTENTIAL APPEARS LOW INTO EARLY NEXT WEEK...
MEDIUM RANGE FORECAST GUIDANCE CONTINUES TO INDICATE AMPLIFICATION
WITHIN THE UPPER FLOW ACROSS THE U.S. LATE THIS WEEK...WITH A
LARGE-SCALE TROUGH EVOLVING OVER THE EASTERN STATES BY THE WEEKEND.
AMPLITUDE MAY DIMINISH LATE IN THE WEEKEND INTO EARLY NEXT
WEEK...BUT AT LEAST A BROAD UPPER TROUGH IS EXPECTED TO PERSIST
ACROSS MOST AREAS EAST OF THE ROCKIES. IN ASSOCIATION WITH THIS
PATTERN...A SERIES OF COLD INTRUSIONS TO THE LEE OF THE
ROCKIES...THROUGH THE SOUTH CENTRAL/SOUTHEASTERN STATES...WILL
CONTINUE TO PRECLUDE A SIGNIFICANT RETURN FLOW OFF THE GULF OF
MEXICO...WHILE ALSO SLOWLY CONTRIBUTING TO A GENERAL DRYING/COOLING
OF THE BOUNDARY LAYER OVER THE GULF OF MEXICO.
