An upper level trough of low pressure (“U” shape) is moving through the Pacific Northwest, but a series of ripples in that flow will be followed by an even stronger low that will slide along the coast. That will keep us alternating between periods of clouds and cooler temperatures, and even some light rain or drizzle, then back to some more sunshine and warming temperatures.
