I saw that on my drive home last night. You can clearly see accumulation was elevation dependent. The magic number seemed to be 500'.

Yeah even down here that was around the number...we didnt accumulate anything besides slush but below my hilltop it was just wet.

Upton:

 

A MIX OF RAIN AND SNOW WILL TAKE PLACE...MORE SNOW ACROSS THE
INTERIOR N/W OF NYC
AND MORE RAIN ACROSS THE COASTAL LOCATIONS FOR
THIS NEXT PRECIP EVENT. TEMPERATURES AT THE SURFACE FOR MONDAY MAY
BE LIMITED QUITE A BIT AND TURN OUT TO BE SEVERAL DEGREES LOWER THAN
MOS IF PRECIP IS MODERATE TO HEAVY. THIS WOULD MEAN POTENTIAL FOR
MORE SNOW ACROSS THE INTERIOR
WHILE TEMPS AT THE COAST EVEN TAKING
THIS BIAS INTO ACCOUNT WOULD STILL RESULT IN MAINLY RAIN. TIMING
WILL ALSO BE IMPERATIVE AS MORE PRECIP AT NIGHT WOULD TRANSLATE TO
MORE SNOW EVEN AT THE COAST.

THERE IS LOWER CONFIDENCE IN THE SUNDAY NIGHT THROUGH TUESDAY
TIME FRAME AS MODELS MAY VARY WITH THE TRACK OF THE WEAK LOW AND WITH
ITS CENTRAL PRESSURE WHICH WOULD RESULT IN DIFFERENCES WITH THE
RAIN/SNOW LINE AND AMOUNTS. WITH THE MODELS CURRENT OUTPUT...IT
LOOKS LIKE THERE WILL BE THE POTENTIAL FOR SEVERAL INCHES OF SNOW
ACROSS THE INTERIOR
WITH MUCH LESS AT THE COAST...WHICH AGAIN LOOKS
TO BE MAINLY RAIN. THERE IS THE POTENTIAL TOO WE COULD SEE A WINTRY
MIX AS THE LOW MOVES ACROSS BUT WITH THE UNCERTAINTY IN TRACK AND
STRENGTH OF THE LOW...LEFT AS EITHER RAIN OR SNOW IN TERMS OF PRECIP
TYPES.

I was up near Crystal Springs Mall in the Middletown area and nothing was on the ground.

Crystal run I think u meant.. Yeah that area is 450-500' in elevation. Pretty much all of 17m from Chester to Middletown was snowless but once u climbed in elevation u almost immediately saw accumulation. Like I said earlier 500' was the magic number

Yep, I saw on my drive in that I missed accumulations by about 100 feet in elevation.

Animal and Julian, and anyone else who got accumulation, did your snow make it through yesterday?

Most of it melted away, but there are some residual patches, and some sheltered evergreens are still holding onto some snow. I'm on a south-facing hill and usually lose snowpack faster than my surroundings.

 

There was actually a pretty uniform layer of ice on my pond this morning, for the first time this year.
