Synopsis for the Gulf of Mexico

.SYNOPSIS...High pressure over the area will shift eastward
today in response to a cold front that will move off the Texas
coast this morning. Fresh southerly return flow is expected
ahead of the front. Strong northerly winds and building seas
will follow the front, which is forecast to reach from near
Tampa Bay, Florida to Veracruz, Mexico by early Fri. Winds to
gale force and rough seas are possible off Veracruz behind the
front on Fri, with fresh to strong northerly winds elsewhere.
Winds and seas will diminish from W to E into Sat as the front
moves southeast of the area. Afterward, fresh to strong
southerly return flow is expected to develop across the western
Gulf on Sun along with building seas. The fresh to strong return
will expand eastward through Mon, then diminish to moderate Mon
night.
