THIS FEATURE POSSESSES A LOT OF RELATED CONVECTION. TROPICAL MOISTURE ASSOCIATED WITH THIS SYSTEM APPEARS TO BE ADVECTING TOWARD THE CWA.

WILL GO WITH HIGHEST POPS OUT WEST TOMORROW. WILL GO WITH LIKELY CATEGORY ZONE WIDE TOMORROW. AS H5 TROF AXIS WORKS EAST AND BOUNDARY TO THE N WEAKENS...SEA BREEZE BECOMES PRIMARY FOCUS FOR CONVECTION. BELIEVE ENOUGH PWAT WILL REMAIN FOR CHANCE POPS.
