Early on there was a lot of concern that the storm might go out to sea with only SE of 95 to the coast getting decent snows, which is why Lee's Thursday afternoon forecast was low on areas to the NW. To his credit, he had upped those areas to 4-8" by Friday afternoon and the first NWS forecast map Friday morning had 3-6" for that area, but they also bumped that area up to 6-8" on Friday afternoon.
I don't actually see a problem with trying to give people a heads up that a moderate to significant storm was likely and by Friday night the NWS, Lee and everyone else had the higher snows for the Poconos, Lehigh Valley, NWNJ and the Hudson Valley nailed pretty well. That's just my opinion and you're obviously welcome to yours.
Their bigger miss, IMO, was along and SE of 95 in SEPA/SNJ and up into CNJ/NNJ, where both the NWS Philly and NYC offices had a general 4-6" forecast (warnings for Philly/SNJ and advisories for CNJ/NNJ/NYC, due to the 5" warning criterion S of 276/195 vs. the 6" warning criterion N of 276/195) starting Saturday evening (they had that much Friday morning, but backed off a bit Friday night through Sat afternoon, but upped it back Sat evening) through yesterday. They obviously missed for folks in the 4-6" zone with most of those areas getting 2-4" vs. 4-6". It's a bust but not a "major" bust, IMO as ~3" of snow accumulating on all surfaces making driving a mess, as it was last night is almost as impactful as 5".
