Synopsis for the Gulf of Mexico

.SYNOPSIS...A cold front extends from Fort Myers southwestward
to 23N90W where it becomes stationary to the eastern Bay of
Campeche. The Yucatan Peninsula thermal trough has moved to over
the eastern Bay of Campeche during the overnight hours, and is
just east of the stationary front. High pressure is present over
the area to the north of the frontal boundary. The cold front
will drift southward through this evening while dissipating. Its
remnants will drift back to the west across the eastern gulf
tonight, and gradually dissipate through Sun night. The Yucatan
Peninsula thermal trough will merge into the stationary front
early this afternoon. The trough will again form over the
Yucatan Peninsula each afternoon through Wed, 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 into the NW gulf on Wed morning,
and reach from the Florida Big Bend region to near 24N91W and
stationary to the Bay of Campeche. Strong to near gale force
northerly winds will follow in behind the front.
