The current cold front will begin to retreat NW as a warm front from tonight through Sunday. Fresh to locally strong NE-E winds will develop each evening offshore of the Yucatan Peninsula, diminishing in the mornings. Atlantic high pressure, extending westward across the rest of the area, will change little through Thursday night. CARIBBEAN SEA... An upper level trough passes through the Anegada Passage, to 16N70W, through NE Nicaragua, to El Salvador. Comparatively drier air in subsidence is apparent in water vapor imagery in the Caribbean Sea. Precipitation: Isolated moderate from 11N to 18N.

An upper level trough extends from the 27N45W circulation center to the Anegada Passage of the NE Caribbean Sea. A surface trough extends from 32N49W, to a 1018 mb low pressure center that is near 29N49W, to 25N46W, and curving to 23N46W and 20N46W. Precipitation: isolated to widely scattered moderate from 21N to 30N between 41W and 47W. A surface trough is along 76W/77W from 20N in Cuba to 26N. Precipitation: broken low level clouds and possible rainshowers are within 60 nm to the east of the trough, and within 120 nm to the west of the trough. A ridge that extends from Bermuda to Florida will maintain fresh to strong winds and high seas S of 29N tonight. Fresh NE swells across the same area, and just to the N, will gradually subside tonight. A weak cold front will move southward, from the U.S. Mid- Atlantic coast to the southeastern U.S.A. coastal waters on Sunday. The front will stall E of northern Florida by Sunday night. The front will move to the north as a warm front by early Monday. It is possible that a second cold front may approach the NW part of the area on Wednesday night, slowly shifting E-SE while weakening through Thursday night. $$ MT
