The Memorial Day weekend continues with morning clouds, cool, low temperatures in the 40s changing over to afternoon sunshine and highs in the upper 60s to low 70s. A marine push each afternoon and evening will cool us down nightly and bring in low clouds for the next morning.

Sunday clouds will clear more quickly as sunshine arrives near the noon hour. The extra time in the sun will warm the high temperatures slightly, into the upper 60s to lower 70s.

A trough of low pressure over the Gulf of Alaska will approach, and hang out, over the Pacific Ocean and slightly to our northwest for Memorial Day, Monday. Areas of drizzle over the coast, will be more spotty under morning low clouds inland. The marine layer should dissipate near noon for a sunny Memorial day, highs in the upper 60s to low 70s. The high temperatures on the holiday may be slightly cooler closer to the coast, upper 50s to mid 60s.

By Tuesday and Wednesday the upper trough offshore will sag further south and make the cloudy mornings linger into the afternoon. Clearing clouds should begin closer to 2 pm both Tuesday and Wednesday. Cooler high temperatures will be in the 60s and there will be drizzle along the coast with a few misty morning areas inland too.

June 1st, Thursday, signals a shift to less morning cloud cover for the end of the week and all the way through the following weekend. A ridge of high pressure slowly building up from the south, will become stronger, and bump the cool trough out of the way, finishing the job Friday. Temperatures will be warming up quickly with mid 70s Friday afternoon and with a change to strong offshore flow, mid to upper 70s near 80 over the weekend ahead.
