.SYNOPSIS...

Low pressure will move across the coastal waters today with
moderate east to northeast winds and moderate seas. This system
will combine with an upper level disturbance to produce widespread
showers and a few thunderstorms gradually ending from west to east
during the afternoon. As the low moves off to the east tonight,
the pressure gradient will weaken with light offshore flow and
decreasing seas the result. Early next week, weak high pressure
will ridge into the coastal waters providing mainly light onshore
flow.
