 .SYNOPSIS...
 
 High pressure ridge hold over area waters through this evening
 before breaking down tonight ahead of an approaching cold front. The
 front will cross through the area on Sunday, bringing only very
 isolated shower chances Sunday. Northwesterly winds will strengthen
 in the wake of this frontal passage on Sunday and Sunday Night
 afternoon: Small Craft Advisories are very likely, with Gale
 Warnings also possible Sunday Night as winds shift to northerly and
 then northeasterly due to strong high pressure wedging down the
 southeastern seaboard. High pressure will then gradually weaken over
 the southeastern states early next week as coastal troughing
 develops over our local waters. Small Craft Advisories and/or 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.
