Synopsis for the Gulf of Mexico

.SYNOPSIS...A surface trough drifting W across the NW Gulf is 
accompanied by scattered showers and isolated thunderstorms. The 
trough will remain over the NW Gulf on Thu while gradually 
weakening. In its wake, the Atlantic high pressure will begin to 
build westward into the Gulf waters on Thu, with a high pressure 
cell developing over the eastern Gulf. This high will move 
westward and dominate the Gulf region during the upcoming 
weekend.
