I’m still waiting for the 8-12 inches in my area that the GFS showed for run after run earlier this month…..

The EPS is not showing a KU pattern

If the PNA rise is real and that’s a big if, then you have a major snowstorm pattern. I’ll believe a +PNA when I see it. Let’s see if those 2 models hold it for more than a couple of runs

Central and northern Northern New England should do well….

Looks good for New England

As long as there is a mega -PNA/full latitude trough in the west, we have big problems here, real big. And the La Niña just peaked at moderate intensity in early December, which some said would never, ever happen….it should have been long dead and gone back in October, that’s going nowhere fast. The weak SPV in December didn’t happen either….the SPV is very strong and we have the strongest -PDO since the 1950’s. It’s time to stop listening to the wishcasters and listen to reality. The SE ridge is going to be a real big problem too….look at those blazing SSTs along and off the east coast…..feeding back into it

All the people who wrote off the La Niña as “dead” back in October were dead wrong. It just went moderate, peaking in December. Time to start praying for a major SSW to disrupt the normal Niña progression for mid-late January and February, especially given the severely -PDO/coupled Niña or the pattern is going to torch big time once the tropical convective forcing moves back to the maritime continent as per normal Niña climo, this isn’t last year where the Niña never coupled….

@donsutherland1 They are all very persistent with the -PNA, also, some big questions on what actually happens with the MJO and if it actually gets into phase 8 or does then dies out. Allan explains: Also, the La Niña has now gone moderate, doesn’t appear to be going anywhere soon, it’s effects will certainly continue into January, February, March:

A big concern for sure

I was not trolling anyone. My point is this, the hype about the upcoming pattern on twitter is crazy. This is not even close to 95-96 as some are saying there, which was a classic KU monster snowstorm pattern. 95-96 was a 1st year Niña, coming off a Nino, you had ++PNA galore, +PDO and a +PMM, which lead to a Nino like STJ. Super west-based -NAO, strong -AO, strong -EPO/-WPO and it was off to the races. This winter, aside from there being a La Niña is night and day different, the biggest difference being the huge RNA/-PNA, -PDO/-PMM and we have an extremely well coupled Niña, unlike 95-96 where it barely ever coupled. I respectfully disagree with some about a -PNA not mattering, it’s going to help pump the SE ridge and given the ridiculously warm SSTs off the coast, it’s just going to give it more juice. If there’s any kind of thunderstorm blowup in the SE during a storm formation it will really boost the ridge and then you will have cutting issues. Just my opinion

You are going to get cutters with a full latitude -PNA trough in the west and a SE ridge. Keep following the wish casters and believe that a huge cold and snowstorm pattern is inbound. It’s hilarious

That’s a cutter pattern not an east coast snowstorm pattern

For central and northern New England? Yes I would agree

Here come the “it’s only warm aloft” posts. The severely -PNA full latitude trough in the west, as depicted is a huge problem. It’s a cutter pattern through and through and I don’t care what the abysmally awful GFS shows, there’s no way to sugar coat that look in the long range…huge -PNA and strong SE ridge city, not only that, the blazing SSTs along and off the east coast just act to sustain and positively feedback into that SE ridge and the WAR. Once you get any kind of thunderstorm blowup in the SE, it’s only going to act to pump the SE ridge even more. The pattern depicted in the long range is not anything close to arctic cold or a KU pattern for us

The common theme through the end of the month on all ensembles (EPS, GEFS, GEPS) is the continuation of that -PNA, full latitude trough in the west

@donsutherland1 @bluewave One of the most well coupled Nina’s in history….

You need to move to New England lol

It did yes, but the late November through mid-late December very cold/snowy prediction has been a bust as has the very weak SPV prediction

There have been a few surprises so far since mid-November….remember the “unanimous” predictions for a very cold and snowy end of November through mid-late December? Then there was predictions of a major SSW, SPV split and a record weak SPV for December?……we have anything but a record weak SPV right now:

Mid December looks good? Long range, the GEFS just caved to the EPS and shows a massive -PNA and SE ridge going into late month

@bluewave @donsutherland1 This would also question how long any end of month change lasts….if the models are correct about IO convection firing by the middle of next month:

Allan Huffman shares your concerns:

I agree with you there and I’m not sure where this “SSW”, “SPV split” hype on twitter is coming from, there’s zero evidence of either, it’s clearly a fairy tale…in fact the stratosphere is really ugly right now and may get worse, it’s starting to couple into the troposphere in fact….

You can have a -NAO and a SE ridge at the same time, I’ve seen folks say they can’t co-exist but that’s nonsense. It’s very possible and has happened many times before. That severely -PNA along with the SE ridge flex is going to be an issue. It might be a “gradient” pattern for New England…..
