A lot will be happening this weekend into next week as an extreme cold airmass comes down behind a clipper. The question becomes, will a wave of low pressure develop along the arctic front and bring snow into the East? Some models have the event and others do not. ECMWF has it but the GFS does not. Keep in mind, the GFS did better last week.
I think all the models are hinting at something happening behind the arctic front in the East but just how much snow is unclear. I do know that a swath of 1-8 inches of high ratio snow will move down from the Northern Plains, through the Midwest and Great Lakes into Ontario and Quebec. Chicago for example should see 4-6 inches of snow with more on the north side of town. Chicago will also see highs below zero next week.
Lake Effect snows in Michigan should be fairly impressive behind the arctic front.
