Ridging will persist from the western Atlantic across the northern Gulf through Sun night. A weak trough will form over the Yucatan Peninsula during the evenings, move offshore the Peninsula to over the eastern Bay of Campeche overnight through the mornings, then dissipate in the afternoons. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... Elongated trough from offshore of Colombia to Cayman Islands will begin to drift slowly west this afternoon through late Thu before moving inland across Central America and dissipating. Moderate to fresh trades will persist east of the trough, with pulses of fresh to strong trade winds off northeast Colombia mainly at night. Seas east of Windward Islands will subside below 8 ft late on Thu. ...SW N ATLANTIC INCLUDING THE BAHAMAS... An old frontal trough lingers from 31N72W SW across the N Bahamas to southern Andros Island to 23N80W will meander and weaken through tonight before drifting slowly NW Thu through Sat. Global models vary in movement of this old boundary with GFS fastest and farthest W, and prefer a consensus closer to UKMET- EC solutions. Fresh to strong southerly winds embedded in a few thunderstorms east of the trough will diminish accordingly through tonight. A ridge will build over the waters north of 25N afterward, supporting generally moderate to fresh winds south of 22N east of the Bahamas, but with pulses of fresh to strong winds off the north coast of Hispaniola mainly at night through Sat. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
