.SYNOPSIS FOR WASHINGTON AND OREGON WATERS...A warm front will
lift N across the waters tonight into Thu, followed by a cold
front Thu that will weaken as it approaches the coast late Thu. A
strong low pressure system will pass well W of the area Fri into
Fri night, driving another cold front E into the waters. Another
strong low pressure system will move W of the area late Fri night
into Sat, pushing an occluded front NE across the waters. A
second area of low pressure may form at the occlusion point near
45N131W and then move quickly NE across the northern waters on
Sat. Yet another cold front will move across the region Sun into
Sun night, as the associated low pressure system moves NW of the
area. Another strong low is likely to develop just W of the
waters late Mon into Mon night, driving yet another cold front E
across the waters.
