Today's Euro looks ugly once the cold air moves out, next Saturday looks really toasty. It makes a big storm but takes it to the lakes by day 10. it still shows a positive nao.

otoh, its 8 day forecast last week showed an east coast bliz for Tuesday, so who knows

I guess we'll see if Euro MR forecasts only bust when they show cold and snow

(GFS) PNA, AO, NAO all look unimpressive though right until day 15... not much changing in that regard despite the artic looking different

Ensembles all look slightly better but nothing earth shattering.

PNA dipping down into the negatives on both by 1/8 and staying there.

Several GFS runs have now modeled building heights into AK. A great sign. I think pattern continues now for the next 10 days. Pattern change around 1/10 begins, with differences showing by 1/20. Probably the first east coast threat featuring the metros between 20th-25th.

Im leaning toward forgetting the whole winter. We, granted, have a ways to go, but judging from all of the views, and changing views of the experts on here, hoping for snow maybe a lost cause. I can stand this winter the way it is right now. If you cant get what you want,,want. What you can get!!! Its an old sayng my father used to say to ME ANd he was from Pa snow and cold lover like me.i hope it snows for all of you. But if it doesnt what canyoudo about it?????

But the euro ensemble never showed the snowstorm but did show the cold jolt. Now it shows a warm look that maintains the positive nao.

The euro ensembles look pretty nice in the 11-15 day. They continue the theme of very cold air seeping into the CONUS from western and central Canada. The se ridge doesn't look terribly robust on this run.

As usual, models may be a hair too fast, so if you keep that in mind..I think things seem to be slowly edging closer.

Maybe you are talking about the 6-10 day period Wes but they sound better after that. I think we all knew that following the cold blast another warm up was coming.

At day 10, it's still a bad look, maybe several days after that it gets better, i don't see those progs.

I guess the bad euro weeklies don't matter?

I feel like many are (have been) attached to a mid jan pattern change so they'll of course stick with it. Not to mention a better pattern for New England can still suck for us. But in January it's going to be cold at least twice I'd think..

It will be cold more than once and we'll probably see some accumulating snow. In January that doesn't mean we will have had a pattern change. When the NAO changes and we have a positive pna, then I'll get excited, until then, I think staying conservative will win out. Heck, many were touted a ssw event giving us a change and that never happened. Of course maybe they are right.

We could easily go wire to wire warm. There really is no reason to think there will be a pattern change. I'd still like to see a few snow events. I think/hope we will but they may be in transient patterns that are just mediocre. It is kind of silly to wait for a good atlantic. We are probably going to need to work without one.

You are going to have to build a cold air maker as well. Still 50 freaking degrees at the end of December at 5:30 PM here. :axe:

This is very true. Hopefully some chilly nights but even those have been marginal lately.

EDIT: maybe I will just cover the front lawn in packing peanuts.

Makes sense. I'm probably on the opposite end of those who have "seen" this pattern change for a month or whatever. I like seeing everyone freak out so warm is good. :P

What a difference a year makes. This is my second new years in a row in manhattan visiting my sis and bro-in-law. Last year had boxing day storm snow mountains everwhere. This year I didn't even need a jacket today.

I posted a month ago that if we were still having the same conversation it would be a bummer and sure enough.....here we are.

I'm going to dig into the nao dailies when i get back in town. It's pretty surprising that the nao has been positive for basically 2 months now. I'm not sure how rare that is or if we have ever had a winter with no periods of -nao. We've had winters with all monthlies coming in + but I'm not sure about dailies. This is getting kind of ridiculous!

I thought your original comment was on the operational and not the ensembles...

it was made at 2:05 PM before the ensembles from the 12Z run came out

my point was just that the Euro has stunk in the MR (5 Days+) so a torch days 7+ is meaningless almost

The ensembles have been supporting that mild period for a while now...so there is some reason to believe any solution that gives a warm shot post-Jan 7th.

The pessimism of this thread is astounding to me. The GFS has been consistently showing a "pattern change" in the day 10-16 range for several runs now. It's been showing some ridging in the GOA starting around day 10, flooding the CONUS with cold air.

This - if it happens - would be a significant change from December and hence constitutes a PATTERN CHANGE...

People around here seem to believe that a pattern change must represent a -AO/-NAO. Pattern change simply means a change in the pattern of persistence; just because that change isn't our most ideal setup of a -NAO doesn't; mean it isn't a pattern change.

Heck, the fact that we're getting a transient cold shot this week shows a break in the pattern. we didn't get any cold shots in december for pete's sake!

whatever, and mine was no one believed the euro snowstorm and that the euro ensembles don't support it, that pattern has stunk all winter, that has been the one constant. You are hoping for a change, maybe it will happen, I don't see it. You don't like me saying that so put me on ignore.

Quote this post for verification. There is nothing wrong with this winter and no need for panic, it is behaving how it should given the steady signals, and they won't last much longer.

The MJO is now racing, IO SSTAs are dropping. After this brief tease it should reconfigure in the COD about 10-15 days, before making the big final push late in the month. We'll see the signs on the pacific side first, the jet will buckle along with a disruption of the polar vortex leading to a powerful storm system(s) crossing the nation late in January which with a semi cut negative tilt in the trough will pull high heights into greenland entraining in the process without the flow to flatten it.

Favorable pattern from the very end of the month throughout most of February.

Still a reason for focused convection, but the cooler IO relative to the La Nina in January with the SW budget increasing in January and February indirectly weakens the easterlies, Loop 1 and loop 2 had no hope, neither did a downwelling SSW. Conditions were unfavorable and still are.

The same won't be said about the third loop since there will be less contrast in forcing to hold back the reassembling of the new regime in convection once the MJO goes back to the Maritime regions.

I must be crazy but the only person I'm really listening to is Wes. I mean it's a close one on Wes v BB but...

That said, I don't believe most people have much clue what will happen past D10.
