Check out the video. I show how the dam-breaking high wind event will unfold tomorrow along the I-95 corridor. This was something that Elliot and I discovered 20 years ago, and in fact I did a paper on the event and how it occurs. I wish I could find that paper. Here is the general way it works; cold air gets trapped on the west slopes of the Appalachians and once a storm moves by up the coastal plain, the cold air rushes over the Appalachians and down the east slopes gaining momentum as it does so. A line of low-topped showers or thunderstorms will occur along the leading edge of the cold air and that enhances wind gusts over 40 mph. I have seen events that have had wind gusts over 70 mph. The event will occur Wednesday afternoon.
I posted the AccuWeather snow map because I am in agreement with the snow totals. There might be some surprises across parts of southern Ohio into central Pennsylvania today when the snow band has set up in response to a front that moved into that area late yesterday. The front has set up a natural boundary for snow to develop along, but it will eventually be washed away as the storm brings in warmer air aloft tonight.
I think we will see a backlash of snow all the way down to D.C., Philly and NYC Wednesday evening, but don't expect much in the way of accumulations. Just watch for roads icing over as the cold air comes in.

The same storm that produces severe weather will produce a major storm this weekend.
