Surprised to see some new snow otg.  Keep the faith Kevin-you may be on a nice heater-looks like we possibly will have another muted torch.

Hey snowcrazed-I was poking fun at everyone yesterday-hope you didnt take too much offense.  Besides, recovering from a lingering cold has made me more salty than I like to be.

It's all good. You are right though... I used to get somewhat defensive in the past. I get you though. Feel better ( just got over a nasty one myself ). Just in time to go back to work after being out since Christmas eve!

Another good write up regarding the disappearing La Nina

IT’S TIME TO SAY GOODBYE TO LA NIÑA

What this chart is showing is a series of strong westerly wind bursts across the western and central Pacific, and this is exactly the kind of atmospheric signal that I said earlier this season would start working against La Niña and help bring it to an end.

Under a typical La Niña background state, the Pacific is dominated by stronger-than-normal easterly trade winds, which drive warm water westward toward Indonesia and allow colder water to upwell across the central and eastern Pacific. That cold-water upwelling is what sustains the La Niña pattern, but this is what I believe is now beginning to change.

When we start seeing repeated westerly wind bursts like the ones highlighted here in yellow, the atmosphere essentially begins to flip the script. These westerlies weaken or oppose the trades, allowing warm water to surge eastward across the equatorial Pacific. That process triggers a downwelling Kelvin Wave beneath the surface, carrying a large pool of warmer-than-normal subsurface water toward the central and eastern Pacific. Once that warm pool begins to surface, the cold anomalies tied to La Niña lose their foundation and the pattern starts breaking down, and this is exactly what I’ve been talking about for quite some time.

This isn’t an isolated blip or noise in the data. It is a structural shift in the coupled atmosphere–ocean system. The more frequent and sustained these westerly bursts become, the harder it is for La Niña to maintain itself, and in my view, the system is now gradually transitioning toward a neutral, or potentially even a weak warm-phase background.

I’ve circled the yellow westerly wind bursts on this chart, and I want to be very clear: these winds are now observed and are happening right now. This is not a forecast. These are current, ongoing observations. In my opinion, these westerly winds should be the nail in La Niña’s coffin. I’ll go a step further. I believe that after this week, La Niña will no longer be the dominant background state in the Pacific.

What we’re seeing here is one of the classic mechanisms that brings La Niña to an end. The atmosphere is no longer reinforcing it. The atmosphere is now actively working against it, and the Pacific is already responding. There is plenty of winter still ahead, and within a week or so, you’ll begin to see that reflected in the pattern.

This is what could have/cause February to not be a flower February.  Just what we wanted. 

I don't think so...RONI and MEI are still safely negative....GLAAM only approaches neutral next month. It's more the +TNH that will save February...a la 2014.

Pattern looks to be pretty favorable by mid-month now. Hopefully something pops ala 12z Euro today. 
 

Ensembles still showing a nice pattern out in the extended. There’s your +TNH pattern…basically -EPO and a near neutral to negative PNA.

I like it. Let’s get some juicy systems out of the SW and slam them into some cold.

PNA looks to stay negative this month

Good for us, but challenging New York City and south. I’m thinking. But with the strength of cold this year I think New York City gets some good outcomes.

That is the type of pattern where you get a slew of moderate SWFEs and redevelopers...not a big dog set up with that gradient.
