NAM was way too aggressive up here with the sleet. Sorry. 

Agreed. It was def the first to really sniff out the potential for taint but was way too aggressive with it. The mix line stalled out between I-78 & I-80. Based on the reports here sounds like it may actually be retreating a bit

I'm looking out my window and it's 100% sleet right now. The NAM won. No other model was as fast or as far north with the mix line. Same thing in DC and PHI. People need to learn the difference between a CLOWN MAP and model output. Prior to 2010 or so this was not a problem. People used NCEP QPF and temperature maps. Hobbiest were better forecasters.

absolutely the nam won here.....its clown map was off mainly because of ratio but for south of 78 it won..it was the first to show the warm nose and stuck with it while other models never had it at all and put out `12-16..the gfs which many weenies clung to was embarrassing

Remember that Pivotal or TT clown maps show the ptype colors based on model output and a ptype algorithm. If sleet is shown on Pivotal that doesn't mean the model precludes a mix of snow and sleet south of that line. And yes the HRRR has done a good job of sagging the mix line south. It also has the benefit of being run every hour.

It's all or nothing on the pretty pictures.  I have seen output that shows mixed precip, but that isn't great either.

I miss the days when people used the NCEP page for QPF, 925/850/700 temp, 850/700RH & omego, and 500mb heights. The snowmaps from Pivotal and TT that get thrown around online have really caused a dumbing down of meteorology.

You realize how elitist you sound right? I am trying to help you. Just act normal and not like a snob. It will go better.
