    I was looking around yesterday at all the puddles in the fields, the water table is certainly up there these days.

    It’s like a sponge out there. Went to the angry orchard last Sunday before this weeks rain and it was sloppy then. Was wondering if you have the monthly precip totals since October. Can’t remember when I had to drain the pool so many times vs. years before.

    12.7 inches for the final.

    To call it an over performer would not do it justice, to call the models performance through the whole ordeal pathetic, would be kind.

    Agree, a lot of hair pulling for the last couple of model runs.  I came in at 12.2”, nice to see some snow cover.

    If the 6Z GFS is correct for Trenton to NYC along 95, for example (and we have no clue), it's showing 7-8" of 10:1 snow falling from the sky from 10 am to 4 pm with good looking DGZ snow crystal formation/growth, column temps well below 32F until very close to the surface and surface temps around 33F.  Verbatim, that snow is ;likely going to accumulate easily at over 1" per hour rates and will likely do better than the Kuchera algorithm, which treats a 1500 foot deep 33F layer aloft the same as it does a shallow 300 foot 33F layer right at the surface (it only takes max column temp into consideration, not depth=time at that max temp) and those aren't the same, as less partial melting will occur in the latter case, meaning less compaction and loss of good ratios.  If the GFS is correct.

    Interestingly, the GEFS shows warmer surface temps of 35-37F during the event, but since it's showing a smoothed mean of many members, the ~6" of snow it shows falls over 9-12 hours, so at maybe 0.5" per hour, which is not nearly as dynamic and that could be why there is less cooling at the surface; at those temps during the day and at lower intensity, though, one would expect a fair amount less snow to accumulate.  One would think the Op is more likely to show dynamics better than the ensemble mean, though.  

    Intensity is going to be so important for this storm if the GFS is close to right, especially during the day...

    Nice write up.  It will be interesting when the short range models such as the HRRR and HRDPS are in range.

    And a general 2-3” of QPF thru 274 hours.  And as we know this will flip flop like a fish out of water for the next runs. Some better sampling in the next few days will get a better read.
