Synopsis for the Gulf of Mexico

.SYNOPSIS...Fresh to strong SW to S return flow has developed 
over the NW Gulf of Mexico ahead a strong cold front due to reach
the Texas coast around dawn this morning. A line of showers and 
thunderstorms will likely precede the front as it crosses the 
Gulf. Winds to gale force are expected behind the front near 
Tampico this afternoon and near Veracruz tonight. The front will 
extend from 30N85W to 25N88W to 19N92W tonight, then exit from 
the Gulf Sun morning. This will allow strong winds to taper off 
across the basin by sunrise on Monday. High pressure ridging over
the Gulf from the N will shift E and allow strong SE to S return
flow to develop over the western Gulf by Tuesday morning. The 
strong return flow will expand to the eastern Gulf Tue night. 
Another strong cold front could enter the NW Gulf Wed.
