Lake effect snow generally effects fairly small regions and due to it's unpredictable nature, doesn't play a role in our seasonal outlooks. Obviously the very impressive snowfall totals we've just seen along the shores of Lake Erie can effect seasonal snowfall totals, but these extreme types of events are not predictable on seasonal time scales.  The average lake effect snow totals are a part of the long term climatology, but there's no way to determine whether a particular season will see less than or greater than lake effect snows.
