Here’s a big list of lists of fun things to do in Washington state

Washing state is pretty large and has several different climates depending on the region. You can find snow in the mountains, rain on the Olympic Penisula and Puget Sound regions, and lots of wind and even some sun in eastern parts of the state. It is a La Nina year, so colder and wetter than normal conditions are expected.

NOAA runs a site that gives some good probabilities for the various parts of the state.
