Synopsis for the Gulf of Mexico

.SYNOPSIS...High pressure of 1023 mb centered near Jacksonville,
FL is spreading surface ridging over the Gulf of Mexico,
producing a gentle to moderate anticyclonic flow. The high
pressure will shift eastward into the Atlantic tonight, inducing
moderate to locally fresh return flow across most of the basin
Fri through Sat. A strong cold front is forecast to enter the NW
Gulf Sat evening. The front will reach from Mobile, AL to
Tuxpan, Mexico Sun morning, from Cedar Key, FL to the central
Yucatan Peninsula Sun evening, and exit the basin Mon morning.
Strong to gale force winds are expected behind the front, with
gale force winds possible across the western Gulf, from offshore
southern Texas southward to the Bay of Campeche Sat night
through Sun evening. Strong NW gales to near storm-force are
possible offshore Veracruz Sun afternoon. A line of strong
thunderstorms is likely to accompany the cold front as it moves
across the Gulf of Mexico. Winds and seas will gradually subside
across the basin late Mon.
