 .SYNOPSIS...
 
 High pressure centered over our local waters will shift offshore
 tonight. Arctic cold front will enter the southeastern states on
 Saturday night, with this boundary pushing across our local waters
 on Sunday. Northwesterly winds will quickly strengthen in the
 wake of this frontal passage on Sunday afternoon, with Small Craft
 Advisories likely, followed by possible Gale Warnings on Sunday
 night as winds shift to northerly and then northeasterly due to
 strong high pressure wedging down the southeastern seaboard,
 resulting in quickly building seas. High pressure will then
 gradually weaken over the southeastern states early next week as
 coastal troughing develops over our local waters. Gale Warnings
 will likely continue through Monday morning, with onshore winds
 and seas then gradually subsiding from Monday afternoon through
 Tuesday. Coastal troughing may generate a few showers early next
 week, mainly for the offshore waters. High pressure will then
 shift eastward and off the southeastern seaboard by midweek.
