313 PM EDT Mon May 11 2026



.SYNOPSIS...A weak cold front currently over the NW Gulf will

steadily move southeastward and extend from the Big Bend of

Florida to the Bay of Campeche tomorrow morning, then stall and 

dissipate by Wed. Winds are generally moderate or weaker on either

wide of the front, though showers and thunderstorms will continue

today and tonight along the front. High pressure and quiescent 

conditions will dominate on Wed and Thu. Looking ahead, another 

weak cold front should enter the NE Gulf Thu night and dissipate 

over the E Gulf on Fri.
