Advisories: NONE AT THIS TIME.
________________
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. Your Monday will be warmer, but still lots of clouds and a chance of showers. A frontal system will be approaching the Pacific Northwest by midweek which would indicate the that there seems to be no end to this wet “Springlike” weather pattern soon. We could see a change over next weekend, but it is too soon to get too excited about it until there is some hard evidence it is possible.
