OBS NOWCAST for low confidence possible untreated surfaces icing or possible first measurable snow under 1/4" part of NYC metro sometime between midnight and 9AM Saturday?

OKX issued an SPS for tomorrow morning covering parts of the area and multiple models but not all, have spotty very light freezing-frozen precipitation in our area over night.

mPing may be helpful in addition to monitoring radar developments, especially 4A-9A Sat.  

Questions are: will the expected low top precipitation be heavy enough to measure 0.01 NYC metro and will temps remain at or below 32F in CP overnight. 

Couldn't wait much longer to decide. Graphics below: WSSI-P for winter drivIng habits overnight... ie not even MINOR impact according to the criteria, and the probabilstic snow portal for NYC CP. 

So odds are against but am not waiting this out. Probably no measurable snow NYC but someone in the I95 corridor of NJ-NYC-CT is going to get a little wintry weather overnight... more than the flurries of earlier today. 658P/5

Same here in central Morris County (except for 26F). Been snowing on and off for several hours. Mostly snow grains.

Pretty snowy night out there. Alternating flurries and light snow with intensity gradually increasing since 9pm or so. Probably a few tenths accumulation on all surfaces... could be some slick spots. Nice job by the hi-res models even days in advance. I'm not sure how well models would have picked this up 15 years ago.

Dusting to 1/2” in Chester. All surfaces covered and road crews came thru.

It's pretty cool to see embedded bursts of steadier snow with real snowflakes and maybe 1mi visibility. These bursts are evident on radar as parallel bands oriented transverse to the direction of movement. Model soundings were reflective of the low level pixie dust stuff that's forming below the radar beam. But the heavier banded stuff is actually showing up on radar and accumulating.
