I commute in Montréal, which has fairly similar weather patterns than Rochester, except a few degrees cooler. In 3 or 4 years of winter-commuting with clips, I never had any unclipping issues. Conversely, my problems were the opposite: if I walked too much, ice could build up under the cleats and I would be unable to clip. Not a real issue, though, because there was enough "roughness" to keep my feet over the pedals anyway.
