Synopsis for the Gulf of America
1039 PM EDT Tue May 20 2025

.SYNOPSIS...A weak ridge extends from the Atlantic just E of the
Bahamas W-NW into the eastern Gulf tonight. The resultant pressure
gradient between this ridge and lower pressures over central 
Texas and Mexico will maintain moderate winds across the basin 
ahead of an approaching cold front. The weak cold front will sink
southward into the northern Gulf tonight, stall, then lift north 
and dissipate through Wed night. Another weak front will sink into
the NE Gulf Thu through Thu night then dissipate. High pressure 
is expected to move into the NE Gulf this coming weekend and 
dominate the basin. Winds may freshen in the western Gulf starting
Sat night. E winds will pulse fresh to locally strong along and 
just north of the Yucatan Peninsula each afternoon and evening 
through the period as a trough develops daily and drifts westward 
at night. Smoke from agricultural fires in southeastern Mexico 
are expected to maintain hazy sky conditions across the western 
Gulf through the period.
