Nothing like a new model run (ecmwf) to dampen some enthusiasm. However, and a big however, you can't live and die with each forecast cycle! There are plenty more cycles to run.
So far, there has been really good agreement on the big picture. But those details! Any trends in speed and how far north/south will make or break this forecast. There will likely be an area that looks primo, at least right now. That's likely to be between DC and Philadelphia. Uncertainty increases north and south. North with the possible sharp boundary with little vs lots of snow. That's the case so far NYC and Boston. Uncertainty increases south with mixing issues...Virginia.
Looks like 1-2 feet in the max, 30 possible. Where? You tell me.
This is how these systems typically work. Some are horribly unpredictable (or parts are....) but some are relatively predictable, like this one appears to be, just like Snowmageddon in Feb 2010, one of those cases. We will see.
But it is likely that any trends in speed and north vs south will likely be key in the next few days. My thoughts
