Aifs is likely the ceiling for this one imo. In some regard, I do agree with Dave. An 18z gfs seems most probable...a little less digging with the sw and a more progressive system like we have seen much of the winter. Still a respectable snowfall. But as I noted and Heisy as well earlier today, some of the more progressive solutions on the models are not far at all from a bomb that gets captured (see ICON and aifs) and goes from respectable to MECS/HECS. Too early to say one way or the other....alot of moving pieces in play.
