Synopsis for the Gulf of Mexico
1058 AM EDT Sat Aug 18 2018

.SYNOPSIS...A surface trough will develop along the Yucatan
Peninsula during the late afternoons, then drift westward across
the southwest Gulf waters during the overnight hours accompanied
by a fresh east to southeast wind shift, with the trough 
dissipating along 96W during the late mornings. Otherwise, a
ridge will dominate the Gulf waters accompanied by gentle to 
moderate anticyclonic flow, which is forecast to increase to a 
fresh southerly breeze across the northwest Gulf waters on Sun 
evening, and continue through sunrise on Mon. The ridge is 
forecasted to shift south and extend across the central waters 
during the middle of next week.
