Synopsis for the Gulf of Mexico

.SYNOPSIS...High pressure along the Mississippi valley will
shift E today, and the stationary front located over the NW Gulf
will transition to a cold front before dissipating tonight. A
ridge will build westward across the basin, with a high pressure
cell remaining over the eastern Gulf. Moderate to fresh
southerly return flow will set-up across the western and central
Gulf on Fri and Sat, ahead of the next cold front forecast to
enter the NW Gulf by Sat morning. Increasing winds and building
seas are expected in the wake of the front. Frequent gusts to
gale force are possible behind the front.
