Synopsis for the Gulf of Mexico .SYNOPSIS...A stationary front extends from Naples southwestward 25N86W to 23N89W and to the eastern Bay of Campeche. High pressure is present to the northwest of the frontal boundary. The front will weaken tonight into early Sun. Its remnants will drift back to the west across the eastern gulf on Sun, and dissipate by late morning on Mon. The Yucatan Peninsula thermal trough will develop over the Yucatan Peninsula each afternoon through Thu, drift westward across the eastern Bay of Campeche during the overnight hours, and dissipate over the SW gulf by late each morning. The high pressure will weaken and begin to shift eastward on Mon in response to the next cold front forecast to approach the area. This next cold front will move over the NW gulf on Wed morning, reach from the Florida Big Bend region to near 24N91W and become stationary to the Bay of Campeche Wed night. It will weaken as it reaches from S Florida to the south-central waters and to the SW waters on Thu. Fresh to locally strong N to NE winds will follow in behind the front through Wed night.
