March 2-4th ... first -NAO anchored storm perhaps in years

The thing with the EURO is it continues to follow the southern/eastern convection.  It creates this duel low that never consolidates until its too far SE but that convective low stays with it the whole time as the "stronger" low.

If everything were to bomb out where it looks like it could or should (the X) then it would be able to wrap the firehose moisture conveyor belt more efficiently into SNE.

Euro wasn't the only model doing this either. There's a chance we see a good bump if we can get rid of that.

Good post dude. Something is all fooked up with that Euro run. It’s hard to toss it so close in, but as they explained earlier.. you really have to

It's a tough call. Here's 925...

The EPS individual members have a good deal that look much more like say the NAM with 2" QPF all over SNE.... but there's also a surprising amount (maybe a quarter?) that really have like under a third of an inch north of the Pike.  Like so low that you'd have to toss those considering the other models.

There is a very strong internal struggle going on within the EPS that is odd for that product at this close range.  Certainly not clearing anything up.  I'm fascinated by this.  How close can we get to go-time without a real clear picture.

hydro vs non again?

Yeah the non -hydros def seem to be a little more wrapped...though even the RGEM was being kind of ugly with a secondary eastward center. The NAM was being the most consolidated...and not surprisingly, it has the firehose further north and lasting longer. Even tries a secondary push of moisture around 09-12z for eastern MA.

The euro huggers saying the euro has been steadfast is sorta too much

I mean c'mon 

Last nite was pitiful even in Catskills

Theres so much juice, I’m going with guidance that handles convection better. Remember Jan 4,euro was chasing convection blobs...its last run before go time was still too SE.

Worth looking back at 4/97 H5 charts... maybe I'm giving this too much weight, but it probably helped that the bulk of vorticity circled around to the north of the ULL
That system had multiple low centers too, but they were developing even northeast of the main low, prolonging the CCB into SNE

In tomorrow's case, bulk of vorticity is southeast of the ULL as depicted on current guidance... the entire thing gets tugged out faster.

24-30 hours is still time for this to improve. First out of the gate 12z Nam will be telling as it's the most aggressive at the moment.

Seems like we’ve been taking one step forward and two steps back for days with this storm.

Finally see a positive trend late yesterday with the snow... now suddenly we are losing precip all together

Will not matter to me at this point as it is still looking  a mostly rain event, with a possible attempt at a 1/2" of accumulating snow after hours of rain.  I've had my share of rain this winter.
