At work so just seeing the euro. It sped up the southern stream just a touch and you see the result. Man synoptically it won’t take much either way for this to be a GFS or blizzard version. Brutal event to track for me for how this winter has gone.

Increased spread on 18z eps has me shitting bricks. I really hope the Ai comes back to at least giving us something FFS

Of course here in Philly that was like a 30”+ run we were still in the ccb at 144 hours

Take this FWIW but I just looks at every eps member and the breakdown of NW v DC area Jack v weak/SE members is almost exactly the same 12z to 18z. 
 

The difference is the weak SE misses went from close misses with a ton of snow just to our east to in many cases no stole at all with like 2-4” as the max anywhere.  The weak camp got really weak. The already east camp went way east. 
 

The jack camp also lost some of its crazy 20-30” members. They are more commonly 8-15” type storms. Btw when judging the eps remember it’s a cold storm and they are low resolution using 10-1 and cut off the end of the storm.  So a .7 qpf run is probably a 10” snowstorm.  Comparing eps members to the op is difficult in that way. 
 

What to make of this?  I dunno. It’s good the track among the majority camp didn’t shift much. But it’s not good the weaker solutions didn’t converge at all and went the other way. Spread increased some. 
 

Euro members couldn’t even agree on the 2/19 storm even like 2 days out so not that surprising

Gotta set your expectations based on Nina climo and seasonal trends. With that said, you and I need to keep our expectations low....very low. I am serious when I say that. This is a Mid Atlantic winter and this one is eyeing them up once again.

But it did speed up the SLP. If it gets too far E before the N stream catches up it’ll be a GFS like scenario.

I need a dog

Therapy dog? Lol

It will be alright. You can road trip to Millville probably and get it on another snowstorm for that area.

Yeah I’m not getting too excited yet. I want this at 120 hours for the EPS to look good. We’d have to survive until like 18z tomorrow. 24 hours to go. If it’s under 120 and euro and eps look good I’ll get excited

This is 6 days out, but I'd take another sixteen inches of snow in Dale City FTW!

Your level of dedication to this hobby is inspirational. You've lived in Texas for a while now yet you still consistently pop in here before snowstorms to hype everyone up and root for your old hometown to score. That's next level shit lol! If there was a hall of fame for this board you'd be first ballot.

Ok a few points rattling through my brain

1) there are actually things I like better about this Euro run.  It focuses on the arctic boundary wave associated with the TPV more (as I suspected and hoped guidance would come around to) and because of that it develops the system and starts to mature sooner.  It moves a little quicker which cuts down snow totals from HECS to MECS levels.  But its a much safer way to go, this progression would have a lot less bust potential than relying on the late bomb phase capture tuck scenario of the 12z euro where everything gets under us and we need it to come straight north really to get us...a SW to NE trajectory is much safer if we want to guard against a really bad GFS like outcome which honestly is more important to me than shooting for the moon here.  Yea I would LOVE 20" but if it comes with a big risk of 2-4" instead...I'd rather take a safe 10-15" snowstorm.  

2) The 12z op euro was one of the snowiest solutions across the EPS.  There was one absolutely bonkers run that was a 2016 1996 type redux with 30"+ across the whole area...then there were 4 members that were similar...but the op was an extreme outlier high end solution.  It was probably just random chance that it spit out one of the bigger permutations.  A 8-15" type snow was the more common result across members.  And then there were some "blah" minority results also...BTW among those there were more misses due to over amplified cutters than OTS GFS solutions, but there were a few of those too.  All that to say, the 20" HECS solution was never the most likely outcome even within the euro suite.  

3) anyone who throws a fit if we end up with a 10-15" snowstorm should be taken out back the woodshed and *&^&%*$&&*%&%.  Frankly that goes for a 8-12" storm also... if we end up with some 4" weak sauce ordinary storm sure, if MD gets fringed again sure...if this euro ends up the final result we should be acting like those people in philly after the eagles won the super bowl.  We haven't had a widespread storm like that in years.  We don't live in Vermont.  A 10" snowstorm is a freaking huge win. 

4) The DC-Baltimore area has had 10 HECS storms since 1950 total...and worse only 1 of them came in a la nina winter.  1.  1 more than none.  in 75 years.  So get that out of your heads.  If we do get a HECS then act like you just won the weather lottery because you did.  Frankly we've only even had 8 MECS (this is subjective but by my count) storms in the last 75 years in a la nina.  But that's way better odds than 1.  8x the odds lol.  So I think MECS is probably the reasonable high end expectations here and that should be totally fine.  That's still a super rare outcome!  When I said I think this happens and we have a good chance at a big snowstorm before the winter is over...I wasn't ever thinking HECS.  I was picturing a 8-12" type storm.  

 

It's a brutal hobby though, I feel let down over the 20.8" to 18" drop like i was over Mahomes garbage 8 points over the backups. 

Going to be watching 0z with one eye closed and teeth clenched.

Our is at 9pm.  The Palm baby!

May seem a bit weird but I remember eating at the Palm in the late 1950s. Grandpa, who lived just off Foxhall Road in NW D.C., took us to dinner there once. What I most remember was discovering the "baseball cut" of sirloin. My god was it good!

Ai at 18Z is way out to sea.

You weren't supposed to post it. Lol 

But since you did, I  am starting to think the reason they're launching a new version on 2/25 is because there's a problem.  The 18z run gave us essentially no precip after this weekend. Everything was off the coast. Something wrong with that imho.

If that is true, they should take it down.
