That analog list kind of backs up my point.  There are a few SE misses...but because they were really weak sauce waves not some 16" snowstorm.  The March 2016 storm for example...yea it missed because the wave was a pathetic pos that didn't give anyone more than 2-4".  

Some of the Spring storms are hard to apply because they happened after the thermals had deteriorated such that there isn't much we can take from what would have happened in a colder regime. 

The rest were either DMV area Jacks or storms that Jacked just north of us.  

I counted 7 that were 4”+ for parts of this sub forum- what I think you’re referring to as the DMV jackpots. 3 had 10”+ amounts (I didn’t count the 1/19 date  because it was too far in date from 1/12-13/19).

But only one, 2/06, was a megalopolis storm. That storm as most of us know was very significant, though, as it reached NESIS Category 3.

Going down with the ship as any respectable captain would. I admire this! Keep sailing high and proud on the S.S. PSU2. Regardless how it transpires you win....you called this 4+ weeks ago. Much respect sir.

it would be bittersweet to call a big mid atlantic snowstorm a month out then have it crush Richmond and fringe me

I'll say it again -- I find it interesting that in the Richmond top snowstorm composite, the 500mb trough in the Southeast, US was the 4th strongest 500mb anomaly in the N. Hemisphere. That is so interesting, because it's a 20 day-analog composite of picked-and-choose analogs of Richmond centered snow. So what that tells me is we need those other N. Hemispheric anomalies to really hit. The -NAO extending to the Hudson bay is a big hit -- but the one missing is a <-100dm anomaly off the west coast. At 500mb, there is even a NW, US trough in the Richmond-snowstorm-map! This time we have a slight High pressure off the west coast, meaning that the East Coast trough may not dig as far south, and the wave may be more progressive vs something that really bombs.

Fascinating reads last couple pages for sure. @psuhoffmanHow bout comps where RVA and DCA get comparable snow totals where both get double digit snows? How many of those?

BTW was at the SB parade yesterday. Such a great day!

Almost every scenario like that is a January 2000 type storm which isn't very applicable to this setup.  It's really difficult for Richmond and DC to both jack from a SW to NE wave like this.  Would have to be a crazy large snowfall distribution.  That 1980 storm came really close...JUST south of DC got a lot, I posted that above.  Again the H5 was tracking much further south than this setup.

A 'SE miss' isn't the same as places relatively further SE forecast to get somewhat higher amounts of snow, which is what the preponderance of current guidance is depicting. Ofc current guidance may not be completely correct about that and some adjustment NW can still occur. 

I don't waste hard drive space remembering specific bad storms but I always thought a SE miss was a whiff north of EZF and flurries in Wes' yard at best. The infamous VA Beach shellacking with broken clouds in the DMV is another one. 

If the majority of the sub gets accum snow, it's not a miss or a whiff in my book.

I was looking for storms where the jack zone was Richmond to Delmarva area (similar to what the miss solutions are showing right now) and all of the storms I used did deliver some snow to the whole area...Most still got 6" or so back to 95 and a lesser type storm the further NW with like 2-5" where I am.  I was trying to see if this pattern fits the composite for a storm like the ensembles are hinting at...a 12" type storm for those places and a lesser storm 95 west.  That just wasn't what I found.  I looked at about a dozen storms and didn't see any like this.  Doesn't mean there aren't any, I didn't look at every storm to ever hit that area of course.  But this would not be a common H5 for a storm with a snow swath that far southeast.  That typically featured a H5 path across southern VA or NC.  Then when I went looking for analogs with a cutoff H5 over the upper midwest tracking through OH and MD or PA, most of the storms were actually NW of 95 jacks.  That's just what I found.  So "confused" describes my attitude towards the guidance.

I was glad to see it on that list because it was one of the storms I identified with a somewhat similar progression when I gave examples earlier.

@Ji I'm going to do something that makes me feel icky and dirty... quote (or in this case paraphrase for copyright reasons) JB.  

He just posted that in this pattern we should be more worried a storm comes straight up the coast not OTS.  Also pointed out the confluence zone is up in Canada, and shout out to you, pointed out what you did about the 18z euro actually trending better at H5 but somehow east at the surface.  

The silly part...said the GFS and Euro are suffering from feedback...I swear he just says that anytime the models don't agree.  I think they are in error but that's like a easy button cheat code thing to say.  But I actually agree with the rest of it.  UGH whats happening to me.

JB is due for a stellar call.  I recall the early 2000's when only he nailed a storm to come North, ( think he followed the Canadian model ) it did and caused massive snows in our area. The JB index is at a ATH.

I used to correspond with him quite a bit through email when I was a meteorology student at PSU.  To be fair he was really nice, responsive, willing to help when I knew next to nothing, and was very informative.  Which is maybe why I took it so hard when he went full tilt cray cray (or sellout if its all just an act) and become what he is now.

at least its a +PNA lol 

Yeah, with the MJO.

Scandinavian ridge is building another -NAO bout potentially in the long range, but the +QBO/Weak Nina impact on the Stratosphere has been strong this Winter -- it's been hard to sustain a -AO with such a cold 10mb layer. It's actually been a surprise we've had so many -AO periods, but they generally aren't sustainable with such a fast flow in the upper atmosphere. 

Fits the seasonal trend of late - we are getting -NAO's, about average to even slightly above average, but they are in continuum less than average.

Another miss on the AI. Here's how it does it. Basically  the tpv becomes a wrecking ball and just drops in too fast and is big. Scroll forward from this spot. It's the only 500mb map worth anything from the AI.

Richmond's 20 greatest snowstorm days since 1948, based on the Feb 20 date. Pretty close to the current projected pattern.. 3 troughs Pacific-US-Atlantic around a -NAO, ridge extending into the Hudson Bay.. 

1A-65.gif

1aa-30.gif

That difference off the West coast (ridge vs trough) could be a reason why it will be a flatter storm, vs a more S->N amped one. 

I would double check the dates, I don't recognize a few of them like 4/5/1980.

I could see this system being further west if there’s more phasing since the high isn’t exactly parked over Quebec, though I still think this system has the most potential further northeast. The NS just doesn’t seem diggy enough for our latitude…at least for now. I think by 12z tomorrow the goalposts are gonna tighten enough that we’ll have a better idea of where the greatest max potential is.

Just step back and look at this... (18z EPS) and tell me...is "oh no that might get suppressed" really what pops into your head?  What am I missing?

Without looking at the surface and just by these maps, I’d worry about it missing me to my north

I am going to get destroyed for saying this but the 18z euro was a better run. The kicker was better..the 500mb was better...consolidated and not as stretchy...it was just a hair off in the phasing

I know u didn't ask me, but it does get N and isn't suppressed. The problem is the kicker pushes it all too far east before it can begin the move to the N. At least that's the way I am seeing it. Up top looks fine....weakening block. 50/50 progressing along and confluence where we like it. I am convinced that vigorous kicker is the culprit. Without that kicker it comes N sooner. 

Eta: kicker, not licker. Fixed typo stupid screen protector

Is that a kicker system in the Rockies as our storm moves east? The trough moving through out there. Maybe that’s what’s getting in the way of a full blow up? admittedly not great at deciphering 500mb maps

So it's not just me seeing that? That feature has been a thorn in my side since this threat surfaced. Not allowing the pna to spike more, it just plows thru the damn ridge. A vortmax on a mission....to crush east coast weenie dreams.

I feel like that oughta be on a T-Shirt...and distrubted to everybody here, lol

But seriously...what could be the disconnect here? Is a storm just gonna magically defy what's going on at that level?
