An upper level trough of low pressure (“U” shape) has moved in along the coast and will keep us alternating between periods of clouds and cooler temperatures, and rain or drizzle and even a thunderstorm thrown in for good measure, then back to less cloudy and slightly warming temperatures until late next week. A frontal system weakened as it moved across the Pacific Northwest and is just one of the waves headed our way. There seems to be no end to this wet “Springlike” weather pattern.
