While the strongest winds of 60-70+ will only last 1-2 hours, there will be 4-6 hours prior to that of winds gusting 50-60mph. That in itself will cause big issues. South winds in NE cause problems
There are some similarities with this event and the screamer in 96 that melted 3-4’ of snow in 24 hours. Does anyone recall how strong winds were in that event, and did the strongest winds occur over snowpack or after it had melted?
