.SYNOPSIS...
High pressure will extend across the local waters through tonight.
Widespread sea fog will continue through at least midday, with some
improvement near the coast during the early afternoon. As the east
coast sea breeze develops late afternoon, fog will shift inland into
tributaries and linger through early Saturday morning.
Southwest winds develop Saturday ahead of an approaching front,
which will reduce fog coverage by midday. The front will move across
the local waters Saturday night into Sunday with a chance of passing
showers. Stronger northwest winds develop Sunday with Small Craft
Advisory conditions through early Monday, with occasional gusts near
Gale Force. Winds and seas fall below Advisory levels late Monday
into Tuesday as high pressure builds north of the region through
Tuesday.
