.SYNOPSIS...

Winds will be southeast to south today into tonight over area waters
as high pressure becomes situated east of our area. Prevailing
westerly winds are then expected from Saturday through at least

Stronger high pressure will build down the southeastern seaboard
early next week in the wake of this boundary, likely pushing the

redevelop over the area waters by Tuesday.
