A ridge axis extending southwest from the Florida Big Bend to central Mexico will gradually weaken today allowing a cold front to move southeast off the Texas coast tonight. The front will stall east to west along 26N on Fri night, then lift back north as a warm front across the western gulf waters on Sat, and then move northeast across the north-central gulf waters on Sat night ahead of a second cold front that will sweep east across the north-central and northeast gulf waters on Sun night. This second cold front will stall briefly along 24N on Mon, then lift north as a warm front across the western gulf on Mon night, turning northeast across the north-central gulf on Tue ahead of a third cold front moving off the Texas coast on Tue night. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... A trough over the northwest Caribbean will gradually dissipate through tonight. The pressure gradient between Atlantic high pressure and persistent low pressure over northwest Colombia will support nocturnal gale force winds along the northwest coast of Colombia tonight with maximum seas of 14 ft. The pressure gradient will then relax some through early next week, with the pressure tightening again on Tue with nocturnal gale conditions resuming again on Tue night with seas building again to max of about 14 ft. The next couple of cold fronts will stall briefly across the north approach to the Yucatan Channel. A stronger cold front may reach as far south as the Yucatan Basin on Thu before stalling. ...SW N ATLANTIC INCLUDING THE BAHAMAS... Remnants of a weakening stationary front extending southwest from 28N55W to east Cuba will begin to lift tonight ahead of a cold front moving southeast off the northeast Florida coast on Fri morning. This second cold front will become nearly stationary from Bermuda to southeast Florida on Sat, then lift back north early Sun ahead of a second cold front moving off the northeast Florida coast on Sun night. The pattern will repeat with this second cold front nearly stalling from Bermuda to southeast Florida on Mon night, with remnants of the front lifting north on Tue ahead of a third cold front moving off northeast Florida late Wed. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
