AN SSM/I OVERPASS AT 1117Z SHOWS THAT THE CENTER IS NORTHWEST OF THE PRIMARY CONVECTION...WHILE VISIBLE IMAGERY SHOWS COLD AIR CLOUDS SOUTH OF THE CENTER AND A DEVELOPING COLD FRONT IN THE SOUTHEASTERN QUADRANT. WILMA SHOULD MOVE NORTH OF THE GULF STREAM IN THE NEXT 12-24 HR...WHICH SHOULD FINISH OFF THE REMAINING CENTRAL CONVECTION AND THE REMAINING TROPICAL CHARACTERISTICS. THE LARGE-SCALE MODELS LIKE TO LOSE WILMA IN THE WARM FRONT OF A BAROCLINIC LOW CENTERED NEAR THE NORTHEASTERN COAST OF THE UNITED STATES IN LESS THAN 72 HR. GIVE THE STRENGTH OF THE SYSTEM...IT WILL PROBABLY LAST A BIT LONGER THAN THAT. THE INITIAL MOTION IS A VERY RAPID 045/046. ASSUMING WILMA IS NOT ABSORBED BY THE BAROCLINIC LOW...THE FORECAST TRACK WILL TURN THE CYCLONE EASTWARD OVER THE TOP OF A DEEP-LAYER RIDGE IN THE CENTRAL ATLANTIC THROUGH 72 HR...FOLLOWED BY AN EAST-NORTHEASTWARD MOTION BEFORE DISSIPATION.
