Synopsis for the Gulf of Mexico
503 PM EDT Thu Jul 27 2017

.SYNOPSIS...A ridge will dominate the Gulf waters through the
weekend as a series of troughs drifts E across the NE Gulf. A
trough will develop over the Yucatan Peninsula during the evening
hours before pushing offshore into the SW Gulf each night, then
move W across the SW Gulf during the overnight hours, and
dissipate by late each morning. A weak cold front will reach the
northern Gulf waters on Sat night, then stall from the Florida
Big Bend to 26N92W to the Texas Coastal Bend late Sun night with
a surface low developing along the front over the NE Gulf late
Sun night. The low and front will drift W on Tue as the ridge
rebuilds westward.
