Synopsis for the Gulf of Mexico
326 AM EST Sun Jan 20 2019

.SYNOPSIS...A strong cold front extends SSW from near the mouth 
of the Suwannee River in Florida to the northern coast of the 
Yucatan Peninsula near 21.5N88.5W to the SE Bay of Campeche near 
18.5N92W. Showers and thunderstorms will accompany the front N of 
23N until the front exits SE of the Gulf later this morning. Gales
will continue along the coast of Mexico near Veracruz until 
around sunrise this morning. Surface ridging southward over the 
Gulf will shift E and allow strong SE to S return flow to develop 
in the western Gulf of Mexico by Tue morning. The strong return 
flow will expand to the eastern Gulf of Mexico Tue night. Another 
strong cold front could enter the NW Gulf of Mexico by Wed morning
and introduce another round of gales to the Mexican coast.
