.SYNOPSIS...Moderate to locally fresh southerly winds are across
the western Gulf and gentle to moderate E to SE winds prevail over
the eastern half. Building high pressure across the SE CONUS 
will push a late-season cold front across the Gulf on Wed, and it
is expected to extend across the Straits of Florida and the 
southern Gulf by late Fri. Fresh to strong northerly winds will 
follow the front.
