VALID 270034Z - 270130Z

DISCUSSION...A COLD-POOL-DRIVEN MCS, WITH A HISTORY OF WIND DAMAGE,
CONTINUES PROPAGATE SOUTH-SOUTHEAST AT APPROXIMATELY 40 KTS. IT IS
PLAUSIBLE THAT THIS MCS WILL MAINTAIN INTENSITY GIVEN THE

SHEAR (ORIENTED PERPENDICULAR TO THE LEADING LINE) PRECEDING THE
CLUSTER. ASSUMING THIS REMAINS THE CASE, THE MCS IS POISED TO ENTER
TN BY AROUND 0130Z. A SEVERE THUNDERSTORM WATCH ISSUANCE MAY BE
NEEDED BEFOREHAND TO ADDRESS THE IMPENDING SEVERE THREAT IF THIS MCS
MAINTAINS ITS CURRENT INTENSITY.
