We do get ice and snow in Portland, along with flooding and landslides. No, it's not the same as Midwest, but we do get a few days every other year or so that you just don't drive out in. The black ice around a couple curvy sections of i-5 are notoriously bad at night in winters. (Terwilliger)

I have lived in the midwest, as well as Portland. It is good that Portland only occasionally gets ice, because in like-for-like conditions it is way more dangerous than the midwest. Primarily because of hills. I found driving in snow & ice in the midwest to be mostly a non-event, even on inadequate tires.
