today as a cold front approaches and then surges through the area.
In the wake of the front, strong surface high pressure slowly
migrates eastward across the Southeast U.S. which will maintain
moderate to fresh breezes. Thereafter, breezes slacken as the
ridge moves further out into the Atlantic and weakens.
