Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A stationary front extending from 31N48W to 28N56W and to 24N60W will begin to weaken by this evening. Weak low pressure of 1013 mb is southeast of the front near 23N53W. A trough extends northeastward from the low to 27N52W and to 29N49W while another trough extends southwestward from the low to 19N58W to vicinity of Antigua and Barbuda and into the eastern Caribbean to near 15N68W. Scattered showers and isolated thunderstorms are south of 22N east of 69W. High pressure west of these features will remain about stationary through Fri, then begin to shift eastward into the weekend. The pressure gradient between the low and high pressure to its NW will induce fresh northeast winds north of 25N and east of 65W from Fri morning into the weekend. The low is forecast to slowly lift north- northeastward through Fri night, then weaken into a broad trough on Sat. Looking ahead, a weak cold front will emerge off the northeast Florida coast late Sat night into Sun. ATLC waters from 27N to 31N W of 77W .TODAY...SE winds 10 to 15 kt.
