.synopsis for the southern washington and northern oregon coast...
the typical mid-summer northerly wind pattern continues into
the middle of next week. high pressure remains anchored well
offshore, while thermally induced low pressure sits over nw
california into extreme sw oregon through the middle of the
week. this will maintain northerly flow across the waters.
however, a low pressure from the gulf of alaska might bring
about slight pattern change by the middle of next week.
