Synopsis for the Gulf of Mexico

.SYNOPSIS...High pressure ridging will prevail along 25N through
early next week. A surface trough extending from northeastern
Florida southwestward to the NE gulf near 28N85W will slide east
of the gulf this evening. Another surface trough will move into
the NE gulf early next week followed by a weak cold front that
will move over the north-central and NE gulf waters. This front
will become stationary and weaken to a trough by Thu. The
troughs and front will continue to bring scattered showers and
thunderstorms over much of the NE gulf waters through much of
next week. A surface trough will move off the Yucatan Peninsula
into the Bay of Campeche each evening, accompanied by fresh
nocturnal winds.
