This could be a humdinger. They had a warm fall so Erie is “warm”. The cold air coming down from Canada will pick up huge amounts oof moisture. They have already had snow in Pittsburgh which is an indicator.
What’s unusual is that while the southtowns are currently getting the snow, the big forecast is for tonight through Sunday for northern Buffalo and Batavia.
It appears that the winds will shift around and park over the northern suburbs and give them 2-3 feet of snow.
