Synopsis for the Gulf of Mexico

.SYNOPSIS...A cold front extending from Pensacola, Florida to
the offshore waters south of Tampico, Mexico will reach from
near Sarasota, FL to the central Bay of Campeche tonight before
slowing down and beginning to weaken. A line of strong to severe
thunderstorms ahead of the front will continue to race E across
the NE Gulf today. Fresh to locally strong NW to N winds west of
the front will diminish to moderate to fresh speeds today. Fresh
to strong southerly winds ahead of the front in the NE basin
will diminish later this morning as the front approaches the
Florida Big Bend. The front will stall Fri night from the
Straits of Florida to the south-central Gulf of Mexico before
weakening further through Sat as a surface trough forms over the
SW Gulf. The gradient between the surface trough and high
pressure over the southern U.S. is likely to induce a large area
of fresh to strong N to NE winds over the central Gulf this
weekend. The trough will transition to a warm front on Sun and
lift northward to the NW Gulf by late Mon.
