I have a complete SmartWool base layer -- socks, long-johns, and a jersey. Expensive, but they and a good set of rain gear from J&G Cycleworks in Eugene, Or. keep most of me warm and dry even in the worst rain. For my feet, I use booties that go over my sneakers and under the rain pants. For my hands, I use gloves that I bought at the construction workers supply store on the East Valley Highway. They're Carhartt, are waterproof, and have a bright green reflective top.
Because my commute changed this year to more than an hour each way, I've invested in an electrical glove and boot drier. I was finding that the insides of my gloves were getting wet from the sweat on my hands and weren't drying out between home and leaving again. Now they're dry and warm.
With all this stuff, I'm able to continue my commute from Burien to north of the waterfront every day.
Good luck on that no-rain thing. Looks right now like you *might* be able to ride on Friday.
