Synopsis for the Gulf of Mexico
1019 AM EDT Mon Aug 20 2018

.SYNOPSIS...A surface trough will develop along the western
Yucatan Peninsula during the late afternoons, then drift
westward across the southwest gulf waters during the overnight
hours dissipating along 96W during the late mornings. The Azores
high will continue to extend a ridge axis across the basin
through Tue night. On Wed, a cold front N of the area will
transition to a stationary front along the northern gulf coast
and then dissipate late at night. The remnants of the front will
transition to a surface trough from the Florida Big Bend SW to
the central basin, which is forecast to dissipate on Thu over
the Tampa Bay adjacent waters. A surface ridge will then move
eastward N of the area supporting northerly light to gentle winds
across the basin through early Fri.
