I was wondering if someone with more knowledge could help me understand the soundings and non-optimal snow growth we're seeing. Looking at the observed 0z Monday sounding for GYX that just came out, it looks like the most saturated parts of the column are in the DGZ, but the saturation is incomplete. I'm wondering we have the right temps here but the reason we're seeing finer powder / plates instead of large dendrites is the lack of saturation. Am I understanding this correctly?

Haven't look at all posts, so sorry if this has been already mentioned

WTH is this thing that crosses SNE around late this evening on the RRFS?  You can trace it back to WV.

Gravity wave?  Notice it flips the S to IP over CoastalWx's area.

A strong gravity wave occurred from the Mid-Atlantic ti SNE on 1/4/1994.
Here is my summary I made long ago when I worked at WSI.

A major coastal storm was in progress across the Mid-Atlantic
 states and northeastern U.S.  Elkins, West Virginia recorded
 6 inches of snow in one hour and Syracuse, New York had 5
 inches of snow in a hour for two consecutive hours.  Syracuse
 measured 18 inches for the storm.  Other big snowfall totals
 included 20 inches at Renovo, Pennsylvania and 18.5 inches at
 Tully, New York.  As the storm passed off the New Jersey coast,
 a gravity wave was induced near Allentown, Pennsylvania.  The
 barometric pressure plunged 22.4 millibars from 997.7 to 975.3
 in just 45 minutes at Allentown, and then rebounded almost as
 much in only 15 minutes.  The gravity wave propagated
 northeastward and produced similar pressure fluctuations in New
 England.  Boston, Massachusetts recorded a wind gust to 66 mph.

Walkway was shoveled less than two hours ago, and filling in again nicely.  Part new accumulation, part drifting.  Wind is picking up a bit, and the snow blowing off the roof sounds like granulated sugar.  You can even see sparkles in the pic...
