It would be the most ironic thing in recorded weather history if the GFS 12z happened verbatim as depicted...
On the above scenario, BOS, NYC and PHL all receive > 20" of snow. That has NEVER happened in recorded history from the same storm. Ever.
For it to happen on this, of all years, in this, of all patterns...
There's a first time for everything, right?
Edit: Meant to say that it's never happened in MARCH. Sorry!
