Any good quality gore tex (or gore tex equivalent) rain jacket will be fine for your purposes. Just get it large enough so you can properly layer underneath it.

I started a thread along these lines; there are a number of really great responses, http://www.bikeforums.net/winter-cyc...er-riding.html

I ended up going with a piece I already owned which was a gore tex rain jacket and it's been great so far in the icebox I've been riding in. It's been well below freezing in IA even before you factor in the wind chill.
