Euro is crazy. Hooks around NYC and then comes up and destroys Mass/Boston (shocked).
Everyone mocks the GFS, but the Euro took places from like 18” to nothing in one run.
Warm air rises, cold air sinks. When the warm air rises, it condenses into precipitation and since it’s moving into a cold air mass, the precip falls as snow.
This is not going to be 2016 imo. This could be a big storm but that was historic. If you are expecting 2016 then you are setting yourself up for disappointment.
