.SYNOPSIS...High pressure will remain centered to the SW of the
area tonight while a trough extending N along the Oregon coast
begins to weaken. This high pressure will briefly erode as a weak
front continues to fade south across the waters overnight. The
high pressure to the SW will build back in over the area tomorrow
and tomorrow night and strengthen on Wed with ridging extending E
over the waters through Thu. A weak cold front will weaken this
high pressure as it pushes across the waters late Thu into Fri.
High pressure attempts to build back in Sat but will not reach
the strengths it did mid-week.
