Synopsis for the Gulf of America

423 AM EDT Thu Jul 30 2026



.SYNOPSIS...A surface ridge will remain in control of the

weather pattern across the Gulf region promoting gentle to

moderate winds for the next several days. The exception will be

fresh NE winds off the northwest coast of the Yucatan peninsula

nightly into the weekend. A trough extends from Tampa, Florida

to 26N86W, while a mid to upper level broad trough north of the

area is slowly advancing southward toward a very moist and

unstable Gulf airmass. This set-up will maintain scattered

showers and thunderstorms mainly over the NE Gulf through the

rest of the week.
