It's a Nina, with a primary well west that has the warm advection hang up just south of us. Classic SWFE. It's a perfect case where the cold air is deep enough over SNE and Boston to let them snow like crazy and have it be over before the warm air arrives, while here it's too warm and just miserable and cold rain. I'm surprised honestly we haven't seen more of these this winter. 07-08 had tons of these and drove I-84 south berserk. Very typical for Ninas and its why the Mid Atlantic often suffers bad while New England can have blockbuster winters. :(

It's likely too late for Boston to have that big a season but I can see them cashing in a few times at our expense if we have more storms like these in the next few weeks.

There is a tenor to your posts that has always struck me as a touch odd; that being this fascination with Boston and their snow and how it is always at your area's "expense".

First off, Boston / Logan Field averages....about 150% of the snow NYC receives on average...around 42" to 28" in a normal year. Believe it or not, there are legitimate reasons for this. First off, the difference in latitude is nearly 110 miles! So not only are they closer to sources of cold air; they are have a far better chance to be south of the track of a general mid-latitude cyclone. As a general rule, along the Eastern Seaboard, being further to the north will virtually always guarantee you more snowfall over the long haul...Norfolk averages more than Hatteras, Salisbury more than Norfok, Atlantic City more than Salisbury, NYC more than ACY, Boston more than NYC, Portland more than Boston (and the difference between the last two makes the NYC / Boston delta look puny).

Now as far as your tacit assertion that the NYC area always seems to miss out...I can happily cite scores of storms that just managed to produce good snows in NYC area while areas from Monmouth County south (or just a little below there) just missed out...like the Blizzard of '82...which put down around 10" in NYC but was generally rain south of a line from Barnegat over to Philly (the 40th parallel).

Just look at some of those seasonal snow maps from the last decade on NorthShoreWx's website...sharp gradients in seasonal snowfall are often south of the area just as they are often north...

Logan Airport in Boston recorded a trace of snow with this last event....
