Rode through the winter in Vancouver nearly every day except when icy or too foggy. I usually wore tights but have switched to leg warmers in the morning now that it's getting a little warmer. My legs get wet but they don't seem to get cold on a ride as it isn't much more than an hour. I hang them up at work during the day and they seem to dry out enough by the time I ride home in the evening.
I wear a gore-tex running jacket if it's raining but the gore-tex part is useless and the jacket is too large and baggy. You really just need something windproof for a jacket. Trying to stay dry with a waterproof jacket is hopeless unless you intend to ride slow an easy. I think I'll try a Sugoi Hydrolite Jacket
