Synopsis for the Gulf of Mexico
914 AM EST Wed Dec 11 2019

.SYNOPSIS...A cold front extending from north-central Florida
to 26N91W and to the central Bay of Campeche will become
stationary from Tampa Bay to the Bay of Campeche tonight. The 
front will weaken through Thu, with frontal remnants lifting back 
to the north through Fri night as low pressure forms over the 
west-central Gulf. This low will track northeastward across the 
north-central waters through early Sat, with the associated cold 
front sweeping across the eastern Gulf through Sat night. The 
front will leave behind a dissipating boundary across the far SE 
Gulf on Sun. High pressure will build southward across the central
and eastern Gulf in the wake of this front with fresh to strong 
southerly flow setting up over the western Gulf by late Sun.
