Synopsis for the Gulf of Mexico

.SYNOPSIS...The subtropical ridge positioned between the SE
United States and Bermuda and lower pressures over Mexico will
continue to force 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. Agricultural and seasonal fires over Mexico and Central
America result in smoke and haze over the the SW Gulf and the
Bay Campeche. Mariners may experience reduced visibility in
these waters. Winds will diminish across the Gulf on Fri. A cold
front that is expected to enter the NW Gulf Fri night. Moderate
to fresh N to NE winds will prevail behind the front on Sat. By
Sun morning, the dissipating front will extend from SW 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.
