Synopsis for the Gulf of Mexico

.SYNOPSIS...A stationary front extends from Fort Myers, Florida
southwestward to 24N88W and to the central Bay of Campeche,
while a cold front extends from the western Florida panhandle to
28N93W and inland just south of Brownsville, Texas. Fresh to
strong winds north to northeast winds are behind the cold front.
The stationary front will begin to move southeastward as a cold
front this morning exiting the southeastern Gulf by early this
evening. The cold front will reach from west-central Florida to
the central Gulf by late tonight, then weaken early Thu as it
reaches from southwest Florida to near 23N90W. Fresh to strong
southerly return flow will develop over the western Gulf Fri,
shift to the central Gulf early Sat and diminish late Sat as
another cold front enters the far NW Gulf. This cold front will
move across the rest of the Gulf through Sun night as it
weakens. Expect for scattered showers and thunderstorms to
continue over the southeast Gulf waters through this afternoon.
