 .SYNOPSIS...
 
 Weak low pressure organizing along the northern Gulf coast this
 afternoon will lift a warm front northeastward across our local
 waters on Friday, accompanied by showers and possibly an
 isolated thunderstorm. Weak low pressure will move northeastward
 across southeastern Georgia on Friday afternoon, with this storm
 system's cold front then crossing our local waters on Friday night
 and Saturday morning. A wave of low pressure will then develop along
 this front just south of the northeast Florida waters on Saturday
 night, with widespread rainfall and a few embedded thunderstorms
 likely across our local waters through Sunday. Low pressure will
 then strengthen as it moves offshore on Sunday night and Monday,
 resulting in strengthening north northwesterly winds as rainfall
 ends, with Small Craft Advisory conditions possible from Monday
 through early Tuesday.
