A renewed push of marine air, from the coast, has filtered inland to start Memorial Day cool and cloudy, with a touch of drizzle. Morning low clouds will fill the lowlands around Puget Sound and low temperatures will begin in the upper 40s to low 50s. Sunrise is 5:18 a.m. Skies will clear gradually from noon to 3 p.m. with sunny skies for the rest of the holiday, high temperatures will be in the upper 60s to low 70s.

Tuesday a large trough of low pressure over the Gulf of Alaska will have a cooling impact on western Washington, along with spotty areas of drizzle. The weather pattern of morning clouds and afternoon sun will remain the same, except for how long it will take to get to the sunshine. Tuesday, late afternoon sun will bring highs to the mid 60s. Wednesday, the clearing happens by evening. Wednesday should be the coolest day of the week with the least amount of sunshine.

The table turns Thursday when a ridge of high pressure begins to work and push the trough out of the way. Thursday morning with some areas of low clouds, will clear rapidly. With additional sun earlier in the day the high temperatures will be in the upper 60s to low 70s.

Friday and Saturday will be sunny and warm with highs in the mid 70s to 80 degrees. The ridge of high pressure will warm the air-mass as it is seated in Canada but, showers and thunderstorms will spin across eastern Washington and into the Cascade range Saturday and Sunday.
