Based upon the snow climo around here, the Euro map looks pretty close to what I think will happen. NW of DC get 20+, my yard gets 12-14 with rime on top. I think high end we bump those totals up to 6 inches, low end we take 6 away and add a lot more sleet. I think higher end is more likely, but we'll probably end up close to the middle.
Considering we haven't had an event like this in 10 years, just book it.
