Synopsis for the Gulf of Mexico

.SYNOPSIS...Weak high pressure over the SE United States
combined with surface troughing 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 the SW Gulf tonight and Thu
night. Winds will diminish across the Gulf Fri ahead of a cold
front that is expected to enter the NW Gulf Fri night. N to NE
winds behind the front should be moderate to fresh 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 Gulf.
