Well theres been some snow grains or whatever just E of here...not sure what that is from...maybe some weird snow growth. The sounding is certainly below freezing. Its heavy snow SE of there too, so it must just be a weird location of the lift in a small pocket.

I have all snow here with no snow grains.

It's weird; it has made up to Ayer, too - best way to describe is that some small dendrite aggregates passed through a warm layer and balled them up - it isn't clear like pellets; they are white semi-solid. A narrow warm layer west of BOS and E ORH zipping up prior to 700mb closure it seems.

INTENSE SNOW BANDS ARE SETTING UP WEST OF THE DRY SLOT AND ARE MOVING

INTO EXT E NJ/W LONG ISLAND. VISIBLE IMAGERY HAS CLEARLY SHOWN THAT

THERE IS GOOD TEXTURE IN THE CLOUDS ASSOCIATED WITH THESE SNOW BANDS,

WHICH INDICATES IMPRESSIVE SNOW RATES. THE FORMATION OF NEW SNOW BANDS

CLOSER TO THE LOW CENTER ARE ALREADY BEING SEEN IN IR/VISIBLE IMAGERY

AND SHOULD CONTINUE TO FORM IN THE NORMALLY FAVORED LOCATION WEST AND

Maybe some heavily rimed flakes?

Maybe some heavily rimed flakes?

Interesting idea but ... I have seen this before. Snowing moderate to heavy while simultaneous 10% of the particulates are partially melted but refrozen balls.

There has been thunder reported in the area; in fact, this type of particulate behavior is not uncommon during thundersnow. Every one I have experienced did this.
