No they don’t, and I don’t blame anyone for not giving a crap what I have to say at this point..., but here is the deal.  Back on the horse. Analysis. Not using clown snow maps lol. 

this is the setup for day 4 and then day 8 with key features identified

As I said it’s almost a replay do over.  The pattern sort of hit the pause/reset button because of the amplification of the Thursday wave delaying the eventual progression.  
 

Btw it’s possible  if that were to happen with each wave we get through the “reboot” period without ever having the pattern break down before what could evolve mid Feb but one step at a time and that’s rather hopeful but it’s on the table.  
 

So what are the difference that could lead to a better outcome day 8.  Frankly both look good at a quick glance.  It’s not like Thursday is an awful look.  But when you zoom in the spacing issue becomes apparent.  The wave in front has slowed significantly in the last 72 hours.  The ridge behind has shifted east slightly.  The combo is compressing the flow around our wave and limiting its ability to amplify.  
 

Looking at day 8 the spacing seems better.  What sticks out to me is the block is weaker, it’s more just a ridge in northern Quebec by then but that’s fine it’s done it’s dirty work and set up the suppressed flow across the Conus and the 50/50s.  The 50/50 is exiting though and there is more space between the waves here on both sides!  Don’t mind the lesser amplitude of the wave that’s mostly due to the longer lead time washing things a bit.  All features are more muted on ensembles at range. 
 

Flashing ahead to the critical moment we need amplification as the wave crosses our longitude

you can see the difference with the spacing. 
 

All that said...the issues to be careful of here are that the spacing could change. It looked better for Thursday around day 8-10 too then the wave in front slowed down. Also like I’ve said were in a double bind so if the spacing is too great we could go the other way and get rain. But that look there is worthy of interest. It’s basically a do over of Thursday’s setup and I was in love with that look from range so I would by a hypocrite to crap on this next one. Let’s try take 2. 

lol I went through this morning, but with a lot less words :P

I would be shocked because I have not seen things turn better as we get closer in a long time.  That said, if I could get 2 inches then it would double my total for the season.  2 inches is underrated.  It can have impact and make someone happy.   Most prefer 6 inches or more but some are satisfied with a solid 2 inches.  

Hmm

My rationale two days was either a) storm is more progressive (weaker) and we Chet light snow but perhaps better temp profile (maybe) or b) it’s wound up and we get more dynamics and qpf. The reason we’re failing is confluence to the north created by TPV. I mentioned too much confluence and we get no development and southern track. Pretty sure that’s close to what’s happening. I dunno

I don’t think that tpv is the issue. It’s behind the trough axis. It’s close but so long as it’s behind it’s not compressing that much. It’s not helping unless it dives in behind and phases though. But the bigger issue is the spacing (or lack of) between the waves off the coast and Thursday’s storm. The ridge to the west is too close also.

Glad you are back. We need you and this is your life!

Lol. I laughed. GFS was funny. 

I lol'd for real.  What else can we do?  2 days ago we had back to back runs showing us the son of Jan 2016.   And now, not even a passing flurry.   We all knew the GFS was overdone, sure. But we figured a 3 to 5 inch snowstorm.  I would have gladly accepted that.   It is what it is, but the frustration level is real.    It's hobby...we have real lives and hopefully nobody is on a ledge somewhere.   I'm about to pig out on some uber eats and watch the games.

LOL, at this point (could end different I suppose) it’s looking like a legendary performance by the gfs.

I hope we all remember this the next time there's a Euro vs GFS fight.   I gave our models a shot, never again.  The Euro luster isn't what it used to be, but it's still a deadly model to bet against.

All you can do.  Keep on keeping on.  We’ll try again next season...Lord willing.  Cheers!

My rule on the euro worked again. Next time it shows snow and the gfs dosent...the euro will cave

Lp in sw va that gives us no precip. What world do we live in?

We knew we needed that primary to get into WV or OH in this setup because of the suppressive flow. Let’s not act like we thought a typical progressive wave pattern track would work here. Different setup. Just like in a progressive pattern a primary tracking to our west would be no good. Each setup has different variables.
