SYNOPSIS
An area of low pressure will continue to slide
westward along the northern Gulf coast. Meanwhile, a strong area
of high pressure will build westward across the North Atlantic
towards the Florida Peninsula, supporting freshening east to
southeast breezes over the next several days. As a second, weak
area of high pressure builds over the eastern Gulf for the second
half of the weekend, easterly breezes will slacken, becoming
light to gentle.
