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. By Sun
morning, the front will extend from SW Florida to near the
Texas-Mexico border. Fresh to strong NE to E winds are expected
behind the front this weekend over the N and central Gulf.
