MORE MODERATE RIDGING EXTENDS FROM THE HIGH SW'WARD ALONG AND NORTH OF HISPANIOLA AND THE BAHAMAS AND THIS RIDGING WILL TEND TO WEAKEN THROUGH TOMORROW.

A COLD FRONT EXTENDS FROM SOUTH OF NOVA SCOTIA SW'WARD TO JUST EAST OF CAPE HATTERAS AND THEN OVER GEORGIA AND THIS FRONT WILL MOVE SE'WARD TO NEAR BERMUDA SW'WARD INTO N'RN FLORIDA BY TOMORROW MORNING.
