It's not really even flipping around.  It completely lost a storm it's had for like 10 straight runs.

Good point.  I would guess this is one of those weird Euro MR burps where it has a totally new solution and then comes back (weenie, I know).  I remember it did that with some of our other events too.

This looks like a 6z control progression but spacing not gonna be enough

I told you that probably wont work.  Even that control run wasn't going to work and it wasn't even going to be close.  I saw some of the posts about it and went and looked and was like...huh this was going to be way OTS.  The angle that trailing wave is coming in at and the angle of the trough trailing from the TPV makes it almost impossible for that final caboose SW to amplify and come north.  It's going to swing way too far SE before turning the corner.  Plus, with 2 waves ahead of it, its simply unlikely to have enough left along the STJ boundary for it to activate a healthy storm in time.  

Yes, in an ideal world we get the TPV out ahead and then something comes in behind but the spacing isnt even close for that to work.  I was just thrilled the guidance went from keying on the lead wave on Monday/Tuesday to the second wave on Tuesday.  That allows the chance for the front the clear and to get a healthy enough boundary wave like the GFS.  You're going greedy and trying for the next wave which yes if you were to change some variables would have HECS potential but its too late in the game to get those changes imo.  I've been wrong but man would I be really really shocked if that last trailing wave was able to turn the corner and amplify.  I hope I am wrong but that seems far fetched imo.

5 day model losses storm rule? Weenie handbook item from long ago? But having it completely disappear is just so strange! Ensemble time! BUT this is disheartening to say the least

 

this would never happen with a cutter/Rainstorm

You know this is BS.  First of all of course a cutter doesn't just go away because for a storm to cut up into the lakes it has to be way way way more amplified than the subtle arctic boundary wave we are tracking for our snow here.  A very minor difference won't make a 988 cutter just turn into nothing but a subtle difference on a weak boundary wave can.  But cutters change all the time, but we don't give a crap if the snowfall goes from 12" to 6" in Green Bay or if the snow line moves 50 or 100 miles when its 600 miles away from us!

Welp, we've flipped places. GFS looks good and Euro looks sickly and supressed/weak  Barely any precip in the area

Called it this morning, “watch gfs be snowiest model today”

Look I was rooting for a different evolution, but I’d 1000% take cmc/Ukie/gfs over this crap. Let’s see what eps does.

the euro was the only model showing something a few days ago. Now its the only model showing nothing. How is the GFS/GGEM/ICON/UKMET showing something and the euro comes out with this

There were plenty of EPS members with this suppressed nothing solution.  There are two options here... either the Euro op is leading the way and the others are now just where it was yesterday and will catch up to the suppressed idea soon.  Or the op euro just randomly drew a solution out of different chaotic options affected by minor changes and it messed one of them up and it will come around to the others soon.  I have no idea which one it is, and neither does anyone else.

Yea guess you’re right. I’d risk cmc inland vs this route lol

I think the euro DID get the 850 down to bermuda this run.  This means we are in the sweet spot in 5 days

I know you're kidding but I do not think this is the type of setup where we will see a huge NW shift once guidance does settle on a solution.  Right now its bouncing all over because fairly minor changes in a lot of factors have a huge impact on this, so they are all over the place.  But once they settle in on a basic solution I don't expect HUGE shifts NW with the boundary.  This isn't the same type scenario as last week.
