How is this little lobe even possible? I never saw anything come straight down from Eastern Canada. 

It doesn’t magically appear. It originates from the same shortwave the main ULL does. Go back to the beginning of the run and watch progression. It breaks off from the energy coming onshore

I’d be out on this one for Ne and even down to my area in Philly. I’d focus on the 12th right now imo. Unless we see models change that lobe position it’ll be tough for it to come north 

Or unless the lobe is bullshit

You have the blocking that will be present over Greenland.  This current storm slows as it encounters the blocking and that lobe of vorticity has nowhere to go but South and pivot around the exiting low, over the Northeast

If that lobe weren't there, we'd be talking about another storm.  That's not to say something still can't occur but it muddy's up the water.

Most storms don’t come down the line in place from 300 hours out. I tend to see ripples or changes upstream at 120-200 hours where they come in a side door onto the conveyor belt

Probably be gone next run...things will change for sure. Blocking g makes the pattern do odd things...you never know what can pop up? 

It’s there on euro and to a lesser extent, the cmc.

Ah yea you’re right. H5 height field was misleading. Looking at H5 vort is clearer. The shortwave traverses across canada then gets deflected south by Dikembe Mutombo into our weekend system.

Flagrant foul.

The way this last one went bad 24 hrs out, I wouldn’t trust any of those small nuances at this long lead for this weekend..whether it be “bad” or “good” for us here in SNE.   That look and evolution will change going forward.  
And who knows what will come out of it, or how it will affect the next potential system(s)?

maybe we should just nowcast everything

yesterdays system was a prime example IMO of a system that needed to be nowcasted IMO - I was just using various radars -I didn't use any of the mesoscale models since people were complaining about them yesterday and I  had  plenty of notice in advance of what probably would happen in my area just using the radars........

Personally I think we have a better shot with the 12-13th timeframe than the 9-10 timeframe. 

Sort of in agreement here ...  ( just using your post as a launch pad - am aware no one cares... )

Kind of a broad-stroked perspective but given the past 20 years ?   considering the lion's share of snow verification did not take place in a -NAO, and were in fact Pac guided, then adding that this recent NAO's handling: those two aggregated facets =  f* this man    

None of that lends to even wanting to engage in this as a hobby at this time.  Ha, can you imagine the professional that is by trade, forced to examine and eat the shit of this pattern?  I mean the poor schmuck - LOL

I just would rather swipe the eraser lever on this drawing toy known as Internet weather charts... and start a brand new paradigm.  If that means returning to the faster flow, progressive needle threading, so be it. We had better productivity that other way.   

No but seriously ... it seems this convoluted pattern/nebularity isn't handled very well.  That Euro 00z cannot be resolved - even by that particular model's touted acumen and monstrosity of daunting complexity built in, that's a convoluted exercise in fractal apoplexy it's trying to manage in the D5-10.   And given its own recent performance during this pattern ( *relative to just that regime ) ... well, it's beyond its wheelhouse anyway.   

What leaps out at me through it all... the PNA - go wonder ... Pac guided ;)   ... we just can't seem to pop a western ridge/+PNAP expression, which is needed for basic wave position mechanical arguments.
