Synopsis for the Gulf of Mexico

.SYNOPSIS...High pressure along the southeastern U.S. seaboard
will continue to support moderate to fresh SE to S return flow 
over the Gulf of Mexico through Fri. The diurnal trough forming 
over the Yucatan will promote strong E winds over E Bay of 
Campeche tonight. A cold front that is expected to enter the NW 
Gulf on Fri night. Moderate to fresh N to NE winds will follow in
behind the front on Sat. By Sun morning, the dissipating front 
will extend from southwestern Florida to near the Texas-Mexico 
border. Looking ahead, as a surface ridge builds to the north of 
the Gulf, fresh to strong E to SE to E winds are expected on Sun 
and Mon over most of the western and central Gulf. Agricultural 
fires over Mexico and Central America result in smoke and haze 
over the the SW Gulf and the Bay Campeche through at least Sat. 
Mariners may experience reduced visibility over these waters.
