Synopsis for the Gulf of Mexico
1016 AM EDT Thu Jul 27 2017

SYNOPSIS
A surface high will develop intermittently through Sat
night over the NW gulf along a ridge extending from SW Florida to
the Texas Coastal Bend. A weak trough will move E across the NE
gulf waters through Sat. A weak cold front will move off the
Mississippi Delta on Sat night, 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. A thermal trough will develop over the Yucatan Peninsula
each evening, drift W during the overnight hours, and dissipate
over the SW Gulf each morning.
