Finished with .40" and melted of .03".

My street has a ton of salt on it this morning and no rain for at least a week to ensure a dusty mess until further notice.

Some finals, past 24 hr CoCoRaHs  snowfall, and the entire mid Atlantic 2 totals totals from NOHRSC.  If interested click for clarity.

CoCoRaHs data this morning had a bunch of T's snowfall southwest of NYC.  Sometimes I think observers got to it late, wind impacted measuring, or that less than 1/2" was commented as a T-the latter I hope I'm wrong.  Imperfect... but the main thing, many had a little snow to brighten spirits last evening.  

I see nothing confidently more than 0.1" CP snowfall for at least a week.

Walt, JFK only measured 0.1 probably because of that darned wind, but I'm not complaining, it was at most 0.5 inch anyway.  Besides the air was really dry here and we had hours of virga when we were under radar returns for snow and nothing was falling.  We had 4 hours of snow here but were under radar returns of snow for 8 hours.

Thanks for this post Don.

 

I want to add...  The LGA snowfall was on an ASOS T... doesn't work that way in temps 20s. That needs NWS fixing as does NYC and EWR meager or nonexistent w.e.  Common sense tells you from the web cams that this is too low for W.E... I'd use 13  to 1 NYC metro,  as per modeled snowratios prior to the event.   Guess that doesn't mean much in the big scheme of things except when someone goes back to verify model qpf, or check on days with measurable w.e.

 

JFK is also too low at 0.1 probably because of the wind but see my above post, we had very dry air here and were under 8 hours of radar returns showing snow, but it only snowed for half that time or 4 hours.  Half an inch is more accurate, but in the end it doesn't matter much.
