The models have been targeting the first few days of the New Year for a potential winter storm along the East Coast. But there is also utter chaos in the models, with everything from a major snowstorm to ice to rain to nothing. To illustrate this, I grabbed the GFS ensemble forecast chart – courtesy of the PSU EWall – valid for Thursday, January 2, at 1 pm, EST (see above). This is just one model and its tweaks and reruns, and does not account for what other models are saying for the same time. I annotated the image to make it a bit easier to interpret.
