 Major disruptive storm to affect much of the east.

Energy in the SW will move out phasing with energy coming from the north. Dual lows will form, one in the gulf running up the apps or just west, and another off SC/GA and going up coast. Not the fastest system. 

Ahead of the system a near record 1052mb high will bring down record breaking arctic air across the northern half of the country. As the storm ejects from the SW, this will result in warm air in front of it riding up and over the arctic air.  The result is a wide area of winter weather, with snow, sleet and freezing rain over most of the eastern states.  Below are the Euro and GFS ensemble snow fall predictions. Note the widespread 6+ amount. 

This is the National Blend of Models

To the south of the heavy snow line, there will be significant icing.

The operational models more extreme. Canadian being the furthest north. Expecting high ratios in the Mid Atlantic and Northeast as temps are in the single digits and teens and the DGZ is low and large. 

What can go wrong?  Phase isn't as strong or timed differently. If the northern system gets stronger and buckles the jet more, then the storm can go north. However, there's a pretty strong banana high that it has to move. Not sure about how we get this storm south at this point though. It's a really wide 12-18 swath going from the PA/MD border to Canada/NY border. While the edges can fluctuate 6" or so, we are pretty much in the middle.  It would have to shift south by 400 miles, which I guess could happen if the northern stream just continues east instead of diving into the mid west.
