Area Forecast Discussion National Weather Service Key West FL 1056 PM EST Thu Mar 4 2021
DISCUSSION. Water vapor imagery highlights a long wave upper trough axis pivoting to the east of Florida. A mid level cyclone is moving into the Plains, north of a large mean layer ridge complex over Central America and the Caribbean. A small and weak low pressure system is lumbering to the south near the northern Bahamas, enhancing the kinematic fields spilling south through the Florida Keys and the southeastern Gulf of Mexico. Northwest to north winds average 11 to 16 knots, tending higher to the west. Winds are a little stronger between Nassau and Bimini, with several ships showing winds gusting above 20 knots. Temperatures across the island chain are in the mid 60s with dewpoints ranging from the upper 50s to lower 60s. Skies are partly to mostly cloudy, although a clearing trend should commence in the next few hours. The KBYX radar is echo free. The forecast is on track and needs no adjustments.
MARINE. A weak low pressure system will lumber to the south near the northern Bahamas tonight. Another area of low pressure will dive through Florida Saturday and Saturday evening, pushing a frontal boundary through the coastal waters of the Florida Keys. Freshening northwest to north breezes Saturday night will become strong and turn to the northeast on Sunday and Sunday night, turning to the east by Tuesday or Tuesday night.
AVIATION. Occasional BKN CIGS at 030-035 will persist at the EYW and MTH terminals through the next few hours. Northerly crosswind gusts approaching 20 knots will persist through 12Z. Winds will turn to the northeast and ease on Friday.
