That's a coating around the city, and maybe 1-2" for central/southern NJ and Long Island. Unless there are huge changes, I don't see anyone around here seeing more than that. This is an eastern Carolinas special.

Agreed. Although one more small NW shift of 20 miles or so and it could become a 1-3" or 2-4" type of event for NYC. I have a feeling it's gonna be painful to look at the radar on Wednesday and see the steady precip JUST offshore.

GFS definitely not showing this, FWIW. Have to go south of DC before seeing any real accumulation.

What counts for real accumulation?? Southeastern NJ will see 2-5"/3-6" from this if the models are correct. And LI sees 1-2" and maybe 3" in eastern Suffolk.

If Ocean and Monmouth Counties  and onto Long Island see an inch of snow out a system that 36 Hours ago was

forecasted 300 miles to our South  ,  then you have to take that as a win .

Its not wide spread , but it may just be another example it wants to snow here .

As of right now there looks to be .10 inch of liquid on many of the models from the city S and E .

From Atlantic City, NJ...

AS WE MOVE INTO TUESDAY NIGHT, AN AREA OF LOW PRESSURE IS FORECAST

TO BE LOCATED OFFSHORE OF THE NEW JERSEY/DELAWARE COASTS. THE LOW

STILL LOOKS TO BE FAR ENOUGH OFFSHORE THAT IT WOULD NOT BRING A

SIGNIFICANT AMOUNT OF SNOWFALL TO THE AREA. HOWEVER, THERE IS SOME

LIFT IN THE SNOW GROWTH LEVEL, AND MODEL CONSENSUS DOES SHOW SOME

QPF ACROSS THE EASTERN PORTIONS OF THE AREA, ESPECIALLY FOR SOUTHERN

DELMARVA AND SOUTHEASTERN NEW JERSEY. THEREFORE WE HAVE INCREASED

POPS ACROSS THESE AREAS FOR TUESDAY NIGHT. TEMPERATURES WILL OF

COURSE BE COLD ENOUGH FOR SNOW. THE LATEST MODEL RUNS ARE

INDICATING A SLIGHTLY GREAT QPF POTENTIAL FOR SRN DELAWARE THAN

EARLIER. IN ORDER TO KEEP AHEAD OF THE TREND. WE HAVE DECIDED TO

ISSUE AN WSW -ADVISORY- FOR THE POSSIBILITY OF 2 TO 4 INCHES OF

SNOW ACROSS SRN DELAWARE. OTHER AREAS (PERHAPS CAPE MAY NJ) MAY

HAVE SOME ACCUM SNOW TOO...BUT CONFID IN THIS IS STILL LOW. THE

OVERNIGHT SHIFT CAN ADJUST AS NECESSARY.

Gfs has .09" of precip for JFK with temps in the upper teens. 1"-2" there.

LI is 1"-3" as well on both the GFS and RGEM with both models having ISP at .15" of total precip.

ok, but cape may and southern delaware are pretty far south, so I'm not sure how this refutes what I said about the 0z GFS.

JFK looked more like .05 to me, but if you have the actual output at .09 I won't quibble over that.  As have been pointed out in endless threads, snow ratios are not merely determined by looking at surface temps.  20-1 ratios are not commonplace.

Bottom line all it will take is another 75 mile shift NW & city is comfortably ensconsced in 1-3 territory when we had less than 10% chance of flurries this time last night.....Just sayin
