In kind of punting Sunday night for anything more than mode flakes, maybe someone scores an inch, but it looks very underwhelming.

I'm much more interested in mid week, that seems to be growing some legs, still an eternity away in this type of pattern.

I envision this pattern similar in ways to the one we saw in January at times. Events kind of pop up on short lead time, and deliver small/moderate events potentially.

BTV is also in agreement with my punting the rest of the month: .LONG TERM /MONDAY THROUGH THURSDAY/...
AS OF 315 PM EST FRIDAY...NOTHING NEW IN THE LATEST DATA THAT SUGGESTS
WE DEVIATE FROM THE OVERALL THINKING OF COLDER AND DRIER
CONDITIONS THROUGHOUT THE EXTENDED. BELOW NORMAL TEMPERATURES WILL
BE THE RULE WITH NORTHWEST FLOW ALOFT BRINGING COLDER AND DRIER
AIR DOWN FROM CANADA. THERE WILL BE A SHORTWAVE TROUGH MOVING INTO
THE NORTHEAST UNITED STATES ON WEDNESDAY AND THIS WILL BRING A
CHANCE OF LIGHT SNOW TO THE AREA. MORE IMPORTANTLY...A LARGE UPPER
LEVEL LOW PRESSURE SYSTEM BUILDS DOWN FROM ONTARIO AND MOVES INTO
EASTERN CANADA AND THE NORTHEAST THURSDAY INTO FRIDAY. THE
DEVELOPING NORTHWEST FLOW ALOFT WILL DELIVER A SHOT OF VERY COLD
AIR WITH 850 MB TEMPERATURES AROUND -30C BY FRIDAY MORNING. THUS
LOOKING AT TEMPERATURES BELOW ZERO THURSDAY NIGHT AND HIGHS ONLY
IN THE SINGLE DIGITS AND TEENS...WHICH WOULD BE 15 TO 25 DEGREES
BELOW NORMAL FOR THE TIME OF YEAR.

 

 

We will be falling back into negative snowfall departures.

I'm thinking the coastal plain doesn't do better than 45F tomorrow and Sunday with southwesterly winds.  Sunday night looks questionable at best, the fact that the GGEM is most robust is not a surprise and is not grounds for concern in my opinion.  GFS and EURO are more robust for Wednesday, and I think we get at least advisory snows into Southeastern MA.

Nobody should be punting d5 events.

 

Nor banking on them ;)

 

But agreed, that could bring some light snow up this way.  The seasonal persistent pattern though would favor SNE into CNE and maybe eastern NNE for more appreciable snows.  I don't think anyone would argue that system looks more geared towards those regions over the NW quarter of New England.

What a truly deep, deep beast that is mid week aloft.  

 

There is an intermediate stream impulse that tries to entice the entire SPV to slice in and capture it... and it does, but just too late.  If that can happen 12 hours sooner, you'd have the most epic subsume scenario ever, period!  It would blow 1978 away.  

 

Not sure folks truly appreciate how close that is to being a once/multi-century type of thing
