Synopsis for the Gulf of Mexico

.SYNOPSIS...High pressure across the eastern U.S is building
across the Gulf, behind a cold front that currently extends
across the NW Caribbean. Fresh to strong return flow will spread
to the entire Gulf tonight, ahead of the next cold front. This
front will move into the NW Gulf Fri morning, reaching from
Apalachee Bay, Florida to the central Bay of Campeche Sat
morning. Brief gale-force N winds are expected behind the front
offshore of the upper Mexican waters Fri afternoon, shifting to
offshore Veracruz Fri night. The front will then stall and
weaken across the SE Gulf, and sink slowly SE across the Yucatan
Channel Mon night.
