February 11 -12 Winter Storm Threat

Hadn't seen anyone post the GFS-FV3, which has been extraordinarily consistent on at 8" or more of snow/sleet (assuming the sleet is 10:1 snow) and it amped that up a little bit at 18Z.  Most of the TT map is sleet, assuming the PW graphic is correct with there only being a few inches of pure snow to start off. That would then be about 2-3" of sleet (7-10" of snow at 10:1 vs. 3:1 for sleet) on top of 2-3" of snow (except for the odd strip of <1" on that map, which seems unrealistic) if the models are correct (for a total of about 0.9-1.3" of liquid equivalent as frozen mass). Not so pretty, but high impact, as modeled.

No photo description available.

Why does the Tropicaltidbits keeps showing Northern New Jersey more accumulation while Pivotal weather shows Southern New Jersey more accumulation?  Sorry if that's a stupid question.

Yup its holding serve.  If it was to verify, it would be a mess for some areas.  It will be interesting to see the future runs indeed.
