temp anomalies are fairly below average for the same time period though. i wouldn't expect extended ensembles to have good thermals in regards to individual events - that is most definitely not what they're mad for and you can't disregard a pattern because of controls runs. i get the concern but really i don't see where this is stemming from

Then that makes even less sense. How are the anoms below normal, perfect looking pattern, yet no snow? And of the things that could make a storm rainy...would snow means pick up on discreet features like that? If this is an error I'm wondering why it's been repeated over 10 days of runs...Doesn't make sense.

I don’t know what to make of it. It’s an anomaly that’s unusual and something I’ve not seen before. I’m sticking a pin in it. That’s it.  I’d much rather the pattern look good than the snow products.  The details usually follow the pattern.

because extended ensembles aren't made to pick out individual storms & all. they're mostly used to identify general features like precip anomalies, temp anomalies etc and give u a good idea ab the pattern. using them to explain why a pattern is bad bc it doesn't produce snow doesn't rlly make sense imo bc it's not made for that 

You’re jumping between two arguments here though. I was using individual control runs to analyze why the means might be doing that. The individual runs do pick out wave tracks. They have to because those tracks are a product of the thermal boundary which is a product of the pattern. They’re all related. You couldn’t design a product to accurately predict the pattern but disregard thermals or storm track. They’re all linked. Screwing up one affects the others. 
 

Look I can’t explain it. It’s weird. I don’t get it either. It makes no sense at all to have that kind of blocking and pattern and not much snow south of 40. It just doesn’t. So I pointed out something very unusual. People can make of it what they want or dismiss it. I haven’t really edited my expectations at all based on this. I’m just flagging an oddity and we can come back to it later if it actually goes down that way.

Our next best chance for something other than rain looks to be in the Feb 6-10 window, as the longwave pattern transitions to more favorable. There are quite a few hints on the 0z ensembles during that period. Cold air availability looks marginal, but the atmosphere finds ways to snow in February, especially in a Nino.

EPS has something cooking for the 6th.

yeah i get the concern, but to me the weeklies snow means looks great. there's a constant 2"+ mean for the 7 day snow between the 19th and 28th. the snow axis is gonna be N of us because it's js climo and it's still so far out, so it's smoothed out to the point that it looks unfavorable for us

I'm guessing he realizes southward displaced jet extensions are common during Nino events, although it comes across otherwise. Ofc he has been telling people extended jet = torch for so long, now he is forced to backpedal.

Where the fuck is everybody?  We have an impending MECS on the GFS in less than 105 hours!! if you don't consider the surface temp above freezing and it's during the daytime....start a thread!

Wait..I was joking but...it's all during Sunday night :o

Prob too busy overanalyzing rainstorms and how much snow would be falling from it in the 1960's.

WB Day 11 GFS.... parade of storms with temps cooling ahead of schedule.... buckle up!!!!!

Looks like a double barrell shot for that time with another southern slider in tow on fantasy range.  Close enough off shore to make it trackable. Cold air looks to be in place as well.

this somehow didnt work out like i planned. 

Well, don’t look now but 6z op shows 3 hits down underneath into NC. Right where we want it? 

Btw I’m not worried about lack of snow on the means on the weeklies. It’s just not something to take seriously until discrete threats show up in range.

Heaven forbid!!  On this day in 1967 it was 72 degrees at Staunton!

The 06z GFS op.  gives Boone N.C. 26 inches of snow during early Feb...... The EPS will save us!

People sensationalize EVERYTHING nowadays. Gotta yell at the sky and your followers right?! Lol. Gotta be first too! Haha.

It is a crappy snow pattern and it is happening as modeled. The way out has remained locked in. Doesn't have to be a scorch the earth and leave charred remains to be a terrible snow pattern. Imo, bigger deals are too often made with just about everything since the internet became more important than reality. Hahahaha

a really nice pattern beginning next weekend emerging on the 6z GFS......unfortunately it will be gone at 12z.........nice to see storm after storm after storm threat with some cold around...

The longwave pattern becomes quite favorable by Feb 10. The 6z GEFS teleconnections: -AO, neutral NAO trending negative, -EPO/WPO, slightly +PNA.

that split flow is what we were missing from the mid-Jan pattern. you're gonna get blocking a few days after this look as well

Lots of action in the southern stream on that run. And yeah it looks like the NAO will become more negative towards mid month.
