The problem when someone argues that AGW is causing winters to be warmer or AGW is causing the Polar Vortex to weaken more often than usual. Yes AGW is happening but how it's really effecting weather patterns we still don't seem to have a good grasp on that yet.

This will save us from going back to a La Nina base state. PV-Forecast @PvForecast · 5h nice wave2 @judah47 @MattHugo81 @SimonLeeWx

Oh but we do need the -EPO to get the cold really loading. The positive PNA is only going to give low level cold not the deep stuff that a -EPO provides.

How is the 12z EPS looking?.

The biggest problem I have with this new pattern is there is no cold arctic air in Canada. You want Canada like a freezer, having a positive PNA is nice but it only temporary delivers cold down to the Eastern US.

That is a good thing would give us a -EPO. We need that -EPO for a cold load to drop into Canada. Your positive surely helps you guys out in the eastern US with some cold and would help me some too here with big storm chances but need the -EPO too. I don't see how a -EPO would lead to a return of La Nina?. I heard it's getting weaker anyways heading into a moderate one.

Need a -EPO hopefully it comes soon.

Any hint of a -EPO yet?. Because I find it's good too get cold into Canada.

My point yesterday is we need the help from a negative EPO to get the cold source. Because if you don't have a cold source what good is the positive PNA really going to do?.

Very Interesting Judah Cohen

Well doesn't help with the cold arctic air?. The distribution of it.

A negative EPO too, Really need that.

I don't know about that as there has been bad California wildfires in 2018 as well. That winter was a good winter if I remember correctly.

I have been noticing a mute on the warming in the medium range as the time gets closer. I think it definitely has to do with the 1025 and over highs coming out of Southern Canada. That is a very good sign all we need is one of those to link but with a storm and could have a nice swfe.

There saying too that the winter after this winter which seems over is going to be another strong La Nina.

Hmm I don't think so. Years ago there was a major snowstorm here on Halloween back in 1993 however the winter that year was snowy and cold.

Why you say that it stayed all winter last year. The difference is we are getting this ugly pattern six weeks earlier than last winter.

Yeah no cold air to be found at all.

What does it show?.

How?. Please explain. We need a negative EPO.

Wall to wall to winter. Kidding of course whatever happened to those winters anyways?.

Yeah doesn't seem to want to go away the warm weather pattern. Hopefully December, January and February and March is not like this too.

We had a 11-12 redux last winter.

What were the temperatures like in February that year?.
