Synopsis for the Gulf of Mexico

.SYNOPSIS...A cold front extends from low pressure near 29.5N87W
to 26N94W. The low pressure will track NE overnight and pull the
cold front across the eastern Gulf through Sat. High pressure
will shift eastward across northern Florida on Sun, supporting
strengthening return flow over the western Gulf ahead of an
approaching cold front. This strong front will move off the
Texas coast on Mon, extend from the Florida Panhandle to the Bay
of Campeche on Tue, then continue moving across the SE Gulf on
Wed. Gale force northerly winds are expected west of the front
near the coast of Mexico late Tue through Wed.
