Upper level low pressure (“U” shape offshore coming out of the Gulf of Alaska) is following behind another low that is moving away from us will be controlling our weather for the next couple of days keeping clouds, cooler temperatures, and at least a slight chance of showers over the Pacific Northwest . There will be another frontal system (position shown on Thursday) pushing through Oregon but this one should be dry for the most part.
