Synopsis for the Gulf of Mexico

.SYNOPSIS...A cold front extending from the Yucatan Channel to
across the northern coast of the Yucatan Peninsula to the SW
Gulf near 22N93W will completely push SE of the area tonight,
while a surface trough lingers offshore of Veracruz through Thu
night. Southerly return flow will strengthen Fri night as a low
pressure system develops over SE Texas. This low will track
eastward along the U.S. Gulf coast this weekend, with strong to
near gale S to SW winds expected ahead of the cold front,
particularly across the northern Gulf including the coastal
waters.
