During the last -PDO from 1945-1980 the pna was negative about 80% of the time. So long as we remain in a -pdo cycle, and the last one was 35 years, this is just how it’s going to be most of the time. 

I’ve seen no evidence the last 8 years that blocking can offset a -pdo anymore.  At least not on a grand level. Could we luck into one snowstorm like March 2018, sure.  But even during extreme blocking most storms go well to our north lately. 

 Look what that period looks like now…

But isn’t this just a 2023 version of a similar pattern at the same time of year in 1962

Look at where the core of the anomalies are.  Isn’t this just that pattern adjusted for the warmer base state?  Even during many of the very snowy periods during our last -pdo the trough was out west and the ridge was in the east in the means.  It was just so cold it didn’t matter.  But what happens if we adjust that same exact longwave pattern for todays base state temps and the ridge wins now?  Would that 1962 pattern even lead to that huge early March mid Atlantic snowstorm or would it be further north now?  
 

And I am not saying it won’t snow at all coming up.  I think we could luck into something similar to 2018.  But even if we do, so what?  One snowstorm doesn’t change this larger issue.  This is why.    If we are in another -pdo era, which I think we are since we were long due for a pdo flip, and the pna is going to be negative almost all the time for the next 30 years…we know +NAO periods are going to be awful.  So we need the -NAO periods to be blockbusters with a lot of snow, not also these struggles where maybe we get lucky one time. 

 

No one is saying it won’t ever snow.  It’s snowed over the last 8 years some.  But if bad years are this bad…and even the “good years” are now a struggle it’s not good  

@CAPE is right that we need to see what happens when we get a favorable enso.  But don’t assume that means the PNA issue goes away. During the last -pdo even during some ninos the pna was negative a large portion of the time.  

Look at an extremely snowy Nino month Jan 1966 for example.

The pna was still negative we just overcame it.  

I’m curious myself to see how much of this a Nino can offset. 

The lower heights over the Aleutians is my guess as to what saved us? Brings the source air directly from the Arctic. You are far more educated about this stuff than I am. But that is just my guess.

I am probably one of the few who want a cool Spring. I don't want to see an effing 80 till June. Hold off the inevitable tropical weather as long as possible. Last Spring/early Summer was probably as good as it gets around here these days.

@psuhoffmanRegarding tropical weather, maybe what we need is an active Atlantic hurricane season to stir up the SSTs in preparation for what could be a better ENSO/base state next season.

Can we just package a p03 and p06 together and make everyone happy for once????

P23 and P29 would make most happy too.

Let us get ONE banger to end the winter. Give us an areawide 8-12” storm to get most areas up to about 30-40% of climo and let’s move the fuck on from this shitshow of a winter.

No intent to derail the thread here. Feel free to move if not appropriate.

 

87storms, there are a couple of issues with this:

1) After a three year Niña, we’re almost certainly going to a Niño or at worst warm neutral ENSO for the coming hurricane season. Activity is a lot more complicated than strictly ENSO, but warm ENSO should dramatically reduce Atlantic tropical activity.

2) Even after historically active seasons in terms of absolute activity and tracks in the western Atlantic, it hasn’t done much to temper the anomalously warm SSTs in this part of the basin. You need a wholesale and persistent atmospheric change to reduce those anomalies.

I'd like a copyright on that last one--let that be my valuable contribution for this winter :lol:

Let me ask you this (and my apologies if this has been discussed already): Is the SER a direct result of these SSTs...or is that driven by something else? Someone answered earlier it was a nina thing, but given how strong it's been I was wondering if those warm waters were a cause.
