    Didn't expect this much, 2.3" here.  What did you get @rgwp96?

    I measured 2 and went back to bed and it was still snowing. After shoveling and everything I remeasured 2 but was hrs after it stopped. I prob had the same as you. I’m at an even 20 for the year

    sorry for the delay. RH is relative humidity.  Models are generally very good at forecasting deep layered high humidity precipitation, but are not so good with precip at layers of high humidity below ~3000 feet (example when a dry slot cleans out the high humidity above 3000 feet). In yesterdays case, With still very high humidity trapped below the inversion, and probably a temperature of nearly -8C somewhere in that layer, and just a bit of lift (with the secondary developing near the coast-there was convergence here), fine snow may have been produced because snow generally needs to be generated with ice nuclei in a saturated layer of ~ -8C or colder.  Also, as a side bar...when precip is changed to rain by a warm layer aloft, it can refreeze to ice pellets (sleet), with a temperature of -6C below that above freezing layer, or to ice pellets by a deep layer of sub0C below the above freezing layer. Anyway, hopefully the first part of your message is answered and my reasoning is possibly not the only answer. 

    Walt a Met here a few years ago here  kind of explained the same thing saying the fine snow must have formed right below the warm layer . I’m in butler and had that fine snow as well most of the day . They were needle shaped  when I examined them on my glove.

    Funny thing is, I measured on it and got 2 inches as well.  Now it's freezing rain.  Glaze on everything.

    Sidewalks were terrible this am and  side roads . Temps peaked at midnight at 33 than slowly dropped to a low of 30.8 at 430. What’s odd was the most ice I saw on trees was looking towards riverdale (also butler heights area behind hs )and Bloomingdale . Hills to my west and north  are higher in elevation   (kinnelon and west Milford) had no signs of ice in trees  . I have a decent view of both areas from my street
