No northern stream interaction = no new eng storm

i think that about sums it up

 

and it seems we still have a bit of time to get this to uccur

 

canadian is further north without much N stream involvement that i can see....has the ML low east of HSE but precip well into sne thur eve but HIGH thickness values look to be tickling BOS-BDL basically where the precip is...maybe a warm toungue....dead dynamics.....meh on cmc

 

i see one gefs 12z member that gives us excellent snows and 1 that gives us 3-6.

Definitely not writing this system off but time is waning.   The Euro has really honed in on the VA/MD area over the past couple days and I have felt that area was in a better position for this system.  There are other issues with this system outside of track that make an accumulating snow difficult.  Even if we do get some bands over us from a southerly track it will be difficult to accum with the E flow.  BL will be marginal even with 850s below 0c.  We will need more dynamics to cool that.  I give a SNE snowstorm a less than 20% chance right now based on what I see.

Euro has been too supressed many times this winter.

At 4 days the error has been a few hundred miles or better. My bet is this comes north.

I have nothing invested in this threat, zero.  But at the same time many are basing what happens 3-5 days from now on models that have been fairly inept for most of the winter with threats ejecting off the east coast, ensembles included.

if the n stream gets involved boom phase snow chance

 

if not ......these s stream n trenders wont' trend 500 miles north into a monster block....even if the SW modeled takes a more N path w-e across the miss valley.  plus it's bootleg so like capecod and bob said. no phase no new england snow.

 

so i'm basing this on a monster west -NAO block  and this baby likely getting supress'd by it. if there was NO block i'd think the seasonal trend may wiggle this north. but because there is i don't know how this will get up here unless it's just a huge windfield and isolated showers around the huge low pressure with mid level low off hatteras and 1k getting catpaws potentially

There could be a system tracking south across FL out to Cuba and some will hold out hope that the models will trend north.

I think winds would be more ENE than due east.
