One thing to keep in mind regarding CAD is that the global models very often tend to underestimate how much cold air is in place. There have been many times that snow, sleet, and/or freezing rain has been expected during a CAD event and we end up getting twice as much as the models had shown. I'm definitely not saying we'll all be getting 4 feet of snow out of this storm, but it's worth keeping in mind that the cold air may be more firmly in place than we all currently think. Once we get closer I'm curious to see how the NAM handles it, that model tends to handle CAD events better.
