Cold rain sucks. -20 is actually more pleasant than just above (or below) freezing and raining.
I generally wear a construction worker hoodie in reflective orange & yellow as top layer, and adjust layers below on temperature. As others have said, the point is to stay warm, dry is often futile when active in rain. I haven't pulled that out yet, but it's probably only a couple weeks.
