.SYNOPSIS...

A stalled front will linger across the local coastal waters through
Monday with waves of showers and thunderstorms. The front will
gradually shift southward Tuesday into Wednesday with high pressure
north of the region and a coastal trough forming offshore of the
Florida coast. This pattern will bring prevailing onshore flow and
elevated combined seas. The National Hurricane Center is monitoring
a couple areas of potential tropical cyclone develop across the
western Atlantic this week, none of which are expected to directly
impact the area.
