Hi Brock
Welcome to the club! I don't think there are any formal WKC SK training classes scheduled for the winter. Keep an eye out for the Basic SK class in the spring. Check other local kayak schools for winter classes in the pool (Northwest Outdoor Center, Kayak Academy, Cascade Canoe and Kayak are the ones I know). Otherwise, I'm pretty sure you will get help working on any skills you are interested in learning if you show up at a pool session and just ask.
