.SYNOPSIS...
A weak and coastal trough over the waters will lift northeastward
tonight, with a a few isolated showers possible off the northeast
Florida coast through the afternoon and evening. Otherwise, high
pressure will be the dominant weather feature through the end of
the week resulting in light winds and low seas across the local
waters. Patchy to areas of fog will be possible within about 10
miles of the coast each morning over the next several days. Over
the weekend, winds turn offshore and become breezy as a cold front
approaches and passes Sunday night. High pressure building in
behind the front will move offshore to the northeast early next
week setting up onshore flow and development of a coastal trough.
