Due north wind isn't horrible for roc actually roc sits at widest point for max fetch of 53 miles. Plus only has to travel 5 6 miles inland. Instead of say 20 on a nw wind.
Say we get 20 from storm. At 1 inch precip. Then lake affect gives say half inch. If it's small flakes say 10 to 1. That's still 5 more inches. I could totally see that in a 24 hour period from 12 sun to noon monday
