.SYNOPSIS...High pressure over the Atlantic will extend westward
across the Florida Peninsula today. East to southeast breezes
will gradually slacken today. Weak low level ridging will
dominate through the first half of the week, keeping breezes light
and largely easterly. A weak front may press south through the
Keys sometime Wednesday night or Thursday. In the wake of the weak
front, strong high pressure builds in behind it leading to
freshening easterly breezes through the latter half of the week.
