You have:

An El Nino thread

A Monthly discussion/obs thread- actual a pattern discussion and obs

A specific storm thread

A model times thread- so no one can ask when a model comes out that no one posts in

A storm tracking thread- for radars and other stuff

A banter thread- so all garbage stays in here. This also serves as a long range thread for people to follow the models in the long range to post stuff that will change 100 times.

A Today in Weather History thread- which is always interesting. Thanks again Uncle.

A NW Burbs thread- for our NW posters to have their own spot

A Long Island thread- that is mostly inactive

A Vendor thread- there's no talk about DT and JB every 2 seconds in discussion threads.

A couple other random threads that do nothing to distract from the subforum.

What more do you want?

 

This is just my opinion, but I think it would be helpful if there were fewer pinned threads. I think having 5 pinned threads makes it a bit harder to navigate, because a number of threads get shoved towards the bottom of the page - the ones that actually are active - and some of the top, pinned threads are not active. I think this makes it harder to get to actual discussion and it make the board "appear" dead.

 

A minor detail but I thought I'd mention it.

Archambeault event incoming next week as severe nao begins to relax/flip while the pos pna tries to remain positive. Huge signal there with regard to those teleconnections imo. Something is going to pop between Jan 17-24. I know thats a vague 7 day range but IF IF IF we r going to get something from this epic pattern it will be when the nao relaxes or tries to flip next week. These is support in the ensembles for something during this time frame as well.

I tend to agree. It's unfortunate that 2 of those threads need to be pinned but they do.

-EPO also which could help

 

Ant, you should start a thread ;-)

No way lol

I thought I was the only thinking this. I guess not. I fully agree. Most of our best KUs happen when the NAO goes from -1SD to +1SD. Let's hope that the Pacific will hold up on its end. Otherwise it will suck again.

Last nights GFS splits the 10mb PV at two different times. Need to get this moved up in time. It's all fantasy still and the Euro still says no.

The stratosphere is very quickly becoming a total lost cause, in 2 weeks we are going into February. By the middle of next week we loose all the high latitude blocking and canonical El Niño domination of the pattern begins and continues into February. What's worse, we loose the cold air in both Canada and the CONUS and are left with screaming zonal and semi-zonal flow, pacific maritime air flooding us and all of Canada. Make no mistake about it, it's going to get very, very ugly

Classic stuff, thanks Warmy. So based on this post, you're going with departures similar to December for February? At least +10 right? Put some numbers out there.

Without an SSW, the effects of which would be felt much more immediately than I think you realize (within 2 weeks), I think Feb is +2 with normal snow since there is still the active STJ. Think March would be a lost cause in this scenario as the days get longer.

With a SSW, if guess Feb would be -2 with a persistent -AO, which would last well into March. Both months would be above normal snow and potentially quite a bit above.

Until the Euro jumps on board, will go with the former scenario, which is still very respectable. Tropical forcing will continue out by the dateline as the now more west-based Nino gradually weakens over Feb and March. So, while PAC air could certainly flood the conus, the NPAC low should remain predominantly south of the Aleutians and I doubt we see anything ugly like December.

For everyone else, understand I am not giving up on Winter, just the belief that an almighty SSW will save us from the clear El Niño driven PAC dominated pattern we have seen so far. I believe we will see accumulating snow in February either way since this is a basin-wide event. And because it would be unprecedented for us not to see any accumulating snow.

Having more Pros and less readers equals less activity. Remember. Not everyone is a legitimate forecaster or a Meteorologist.

It would be like having a racecar forum that only drivers could post on, or a car forum only mechanics could post at. In short, reading the musings of experts only would be boring, especially when the main topic is that there is nothing interesting going on....how many people are meteorologists? I only ever met one in real life years ago and he was teaching middle school science and doing the weather locally part time.....and since it is not a licensed field, any happy jack can call himself a weatherman and make a living at it, and some do....

Can you post canonical nino february temperature departures? Thanks. (Not a sarcastic post, genuinely curious how it changes month to month)

Again, SSW events:

 

1) Do not always deliver cold into the continental US...let alone the eastern United States

2) Displace the vortex enough on this side of the pole to deliver the goods

3) Split the PV

 

Just as a heads up as Larry Cosgrove continues to hype everyone up about it.

Quick question: At what site can one find these maps?

 

Many thanks.

This has been covered by a few already, but the first image was just simply the daily temp anomalies on the ESRL reanalysis site.

 

The second I cannot take credit for...that was good old fashioned analog work done by a colleague of mine.

Agreed. However, the progression this winter is eerily similar to that of 1958. 1958 delivered cold air into the CONUS. We've also seen little resistance to the establishment of arctic blocking and, in fact, a near record -AO value occurring as we speak, and all without actual PV displacement.

I've made my thoughts clear on why I thought that Arctic blocking took place.  Largely MJO induced, with contributions from a crazy anomalous Kara Sea high.  If you're relying on the SSW for the goods as far as further blocking goes, you need to wait (my opinion).  They (SSW's) do not have an instantaneous effect on the troposphere...there's a physical process that must take place with a warming event like this.  Even then, it's not a given it delivers cold here.  

 

High amplitude MJO, high amplitude ENSO, high amplitude Kara Sea high...

It's not only Cosgrove that's talking about SSW. It's other social media meteorologists also.
