If anything I believe this helps aid in stj energy undercutting the ML ridge on the West coast and as it ejects east in pieces will provide SWF/gradient overrunning situations for us and more specifically the OV as it runs between the SE ridge which will appear periodically and NS 500mb trof over the GL/NE. That look has been showing up on the LR ens for a few runs but as you noted...la la land for now and nothing I would be too concerned with one way or the other right now. More interested in how the HL players line up going forward the next few weeks. 2 Link to comment Share on other sites More sharing options...

Looking at December with interest to see the validity of whether the recently record high +PMM actually does influence the STJ. Link to comment Share on other sites More sharing options...

In about a week we will start to get an idea if this pattern rolls into December. If so I will get more optimistic. So far so good. This is pretty much my thinking. Nothing alarming at this point. Still most curious to see how the advertised NA blocking plays out. Would not be surprised if it verifies weaker than depicted, and does not persist into Dec. As I mentioned previously, I am not going to bother much with trying to glean anything meaningful from weeklies/climate/seasonal models. I will just continue to monitor the LR ens guidance daily to see how the h5 pattern is 'trending'. Link to comment Share on other sites More sharing options...
WxUSAF Posted November 15, 2019 Share Posted November 15, 2019 Potentially cold thanksgiving week if the GEFS and Eps are right with a piece of the tropospheric PV stuck under the NAO ridging. And potentially a stormy look bracketing thanksgiving as well. 3 Link to comment Share on other sites More sharing options...
CAPE Posted November 15, 2019 Share Posted November 15, 2019 Continue to see favorable h5 looks around the 25th. Who knows if anything will come of it, and yeah lets hope we see something like this in another month or so. 3 Link to comment Share on other sites More sharing options...

CAPE Posted November 15, 2019 Share Posted November 15, 2019 This was h5 leading up to T-day of 1989. Cold powder to right to the beaches. That was a great event for the coastal plain. 6" +. It can happen in late November. Link to comment Share on other sites More sharing options...
frd Posted November 15, 2019 Share Posted November 15, 2019 I can tell you one thing the orientation of snowfall anomalies seem to be lining up a bit differently this late Fall versus last Fall. Totally speculative. I know the Euro Control run is wild beast but you know looking at it last Winter it did depict future snowfall in terms regions rather well. No one should ever put any faith into the 46 day snowfall totals regardless of the model. Maybe the lower latitudes score more than Maine this winter. 5 Link to comment Share on other sites More sharing options...

In about a week we will start to get an idea if this pattern rolls into December. If so I will get more optimistic. So far so good. It is nice to see where we've been and where we seem to be heading as we approach December. 2M temp anomalies are blues of varying degrees for as long as the eye can see. End of the GEFS looks really nice at 500mb so it would seem likely that if things hold, we might be able to score a little early season action. A pleasant way to start tracking season regardless the outcome. Pac seems to be cooperating early on and in my mind has to be a big part of the perty maps. Couple that with some help in the NAO domain and it could feel like normal winter round here. Link to comment Share on other sites More sharing options...

Don't recall the details but the pattern flipped in early Jan to complete suckage. eta- DCA had 15.3" that winter. 12.5" fell in Nov-Dec (9" in Dec). Nothing significant after that until March. Jan was an all out torch following a very cold Dec. Perfect I guess for those who want a cold, snowy, front loaded winter. 1 Link to comment Share on other sites More sharing options...

You'd start to see a SE ridge reflection in that case. So far, we don't see it, which is cause for optimism. 1 Link to comment Share on other sites More sharing options...

Because after Dec the winter was basically a torch. Probably could not have a worse Jan for cold/snow. Plus it followed an extremely cold Dec. It was quite the flip. 1 Link to comment Share on other sites More sharing options...

I wasn't alive for it, but 89-90 had one of the most dramatic pattern flips I've seen. Second coldest December on record in DC (-12.2 departure) to blowtorch January (+7.6) and February (+6.2). December 22-24 1989 was the biggest snowstorm on record for ILM and OBX (15 and 13 inches respectively) while our area was mostly shut out. We did have above average snow for the month but most posters would have been frustrated. 1 Link to comment Share on other sites More sharing options...

Yeah as CAPE was saying I’ve never seen a flip like that. November and especially December were brutal. Then right about Nee Years it flipped. Down in swva where I was living at the time it didn’t snow another flake until St Patrick’s Day. 2 Link to comment Share on other sites More sharing options...

As Ralph said what I see there is a split flow. It's not perfect but I am ok with that look, especially during winter. The southern jet is crashing into the southwest and lowering the heights there but so long as there is riding over the top and a decent pattern to our northeast with lower heights in the Newfoundland regions with ridging over the top of it... those systems should mostly be forced to slide across the south and not cut to our west. That may not work in November, but in mid winter that would be an ok pattern. 1 Link to comment Share on other sites More sharing options...
