Showers Pass out of Portland makes an excellent biking jacket. It's eVent technology and is regarded as some of the best breathable, waterproof stuff out there. Is pricey though ($240) but worth it in my book. I own two of them. You'll have to wear layers though as it isn't made for really cold temps. But that's a perfect combo in my book because I can adjust to my body temp. It's especially all good if you have panniers to put stuff in.
