psuhoffman Posted 6 hours ago Share Posted 6 hours ago I’m not saying this happens. But we’ve seen what the 12z gefs is showing several times. A SER linking with the NAO. But this is different because we have a favorable pacific long wave configuration with a trough centered from Hawaii to just west of AK with a ridge bridge from AK to the NAO. If that doesn’t work I don’t even know what we want for a big snowstorm anymore. If that happens I don’t want to hear “it’s the PDO or the pacific”. I suspect a big part of that is something else. This isn’t complicated. The more heat you add the the equation the harder it is to suppress a SER from over the top. Additionally the warmer storms are coming off the pacific the more they are going to amplify faster out west and pump that SER downstream. That’s a pure “too much heat added to the equation” issue that won’t be fixed by any long wave pattern. That said given enough time I’d still take my chances that something comes off the pacific and doesn’t over amplify and cuts under the NS flow. I’m not tossing any towel. This is just pointing something out. 1 1 2 Link to comment Share on other sites More sharing options...

This led to significant improvements in short-range t2m forecasts. Link to comment Share on other sites More sharing options...

This is just pointing something out. The warm Atlantic has been mentioned in this possible connection. The NAO block the is forecasted may very well linked with the SER diminshing the benefits of the NAO block. Hence the favorable patterm in the long range never happens, but that is too soon to worry about. 2 Link to comment Share on other sites More sharing options...

Depends how we fail. If we get a trough in the east but we just get unlucky with wave spacing and timing that’s ok. Sucks but doesn’t say much about future chances. That happens. But if we have a pacific Nino look with a central pac trough and an epo to nao ridge bridge w split flow and the stj waves all amplify too much out west and the SER can’t be squashed then I don’t even know what to root for if we want a big snowstorm. Yea sure we could root for a typical Nina look and hope to luck into waves like we’ve been trudging through the last 8 years but what’s our path to a legit big snowstorm cause that ain’t it. Our big snow look relies on a split flow with blocking over the top. Waves come off the pac and slide east under the blocked flow. But if too much heat gets added to that setup and there becomes a feedback loop where the pacific waves come in and amplify too much out west which feeds into the SER which is also getting fed by a warmer Gulf…well other than the pacific and gulf cooling what’s the solution. And I’ve seen no one saying they expect the SST trends to reverse anytime soon. 1 2 Link to comment Share on other sites More sharing options...

To say that scenario wasn't/isnt in the back of many of our minds that have been here a while and tracking global h5 tendencies would be fibbing, because that's one of the very few ways we would fail with those high lat looks.

Yes, but as pointed out by @psuhoffman , we do have the Pac in our favor this go around, ( minus the feedback loop ) but still a concern, don't mean to be a Debbie Downer.

Since we had such a fast PDO rise, I’d say we’ve had a +PDO atmospheric pattern and it’s taking time to make an imprint on the SSTs. But it’s still an uphill battle that becomes less and less the longer we hold this pattern. 5 Link to comment Share on other sites More sharing options...
Stormchaserchuck1 Posted 5 hours ago Share Posted 5 hours ago Polar blocking really lost steam on todays 12z GEFS. It's a weak signal in the long range. Last February the same thing happened, people were comparing to 95-96, but in those maps we have 200-300dm patterns, and what the long range models are showing is only 150-180dm right now. Allows other patterns to happen underneath of it. The NAO turning very negative right after the +EPO CONUS ridge now happens with a -PNA And although we still have -nao/-epo in the long range, this is a weak signal... oranges and light red. I would not be comparing to Jan 5th 1996, lol 2 1 Link to comment Share on other sites More sharing options...

Terpeast Posted 5 hours ago Share Posted 5 hours ago Still in wait and see mode. GEFS as depicted will be a cutter on Jan 3, and then *maybe* a follow up wave that slides south of us similar to Jan 2022. Not the big dog we’re looking for, but it still leaves a path to modest success here. 1 1 1 Link to comment Share on other sites More sharing options...
