susqushawn Posted November 12, 2020 Report Share Posted November 12, 2020 Signals of an overrunning setup the days leading up to Thanksgiving. Most 12z guidance has uber cold not too far north with rising heights (at least temporarily) in the PNA and AO regions. For illustrative purposes, here is the 12 GEFS that for now are trending in a better direction, but as we've seen, that Pac energy has been overperforming so need a few more days to see what will stick. I'll probably feel ashamed for succumbing to phanton d10 weenie pattern flips Link to comment Share on other sites More sharing options...
tombo82685 Posted November 12, 2020 Report Share Posted November 12, 2020 Made this thread because the setup doesn't look to bad as of right now. Certainly "could" do something if things come together. Would like to see a better pna ridge out west and some more blocking into Greenland/baffin island area to give the confluent 50/50 low. Could possibly a case where the first low that comes in early tgiving week sets up the system right around tgiving. Regardless, as of right now, tgiving looks chilly per eps.

tombo82685 Posted November 12, 2020 Report Share Posted November 12, 2020 EPS snow mean, this all falls Tgiving week. Obviously further north is best with climo and better shot of colder air but it can work if things I mentioned above come to fruition. 2 Link to comment Share on other sites More sharing options...
tombo82685 Posted November 12, 2020 Report Share Posted November 12, 2020 This IMO is what we need to see happen. You can see the players are there for something. Just comes down to cold air availability and track of the low. We have a -ao and -enao as well as +pna signal. I would like to see a stronger +pna signal, which would give a better drain of colder air southward instead of glancing by to the north. Would like to see -enao trend a bit more robust pushing the 50/50 low southward. 50/50 low goes south it flattens out the hgts along the east coast. Probably see one storm cut to our west, can't see how it wouldn't as there will be a se ridge there again after next weeks cold shot. That storm drags the front through and cold air dives south. With 50/50 low building in and compressing hgts, follow up overunning system tracks over or under us. In a perfect world thats how it would work. IMO, need to see the pacific cooperate first. Thats been the pain in the ass. 2 Link to comment Share on other sites More sharing options...
Heisenberg Posted November 13, 2020 Report Share Posted November 13, 2020 Awesome. I took a glance at the models yesterday and noticed the same thing. Kind of like the pattern in that time frame, but it obviously depends on timing. Link to comment Share on other sites More sharing options...

Heisenberg Posted November 22, 2020 Report Share Posted November 22, 2020 Just for shits and giggles... the 12z Euro & CMC both have a major cold blast at end of run, but both have a trailing shortwave. It’ll change anyway, but I’m getting my tracking boots ready. The 00z para GFS had that wave and turned it into an HECS for parts of mid Atlantic. With the pattern and air mass advertised we’d likely need a well timed -intense closed ULL to get snow in early December. Something to keep an eye on 3 Link to comment Share on other sites More sharing options...

Rainshadow Posted November 23, 2020 Report Share Posted November 23, 2020 This is not a bad outcome (northern stream cold arrives first) as the previous full phasing would have Wreck Of Edmund Fitzgerald the track. Still bleeds into the Euro's bias (which seems has either come back or become worse) of hanging energy too far back. The GGEM is still full boar on the phasing. The GFS has its own progressive issues. Link to comment Share on other sites More sharing options...

Kicker hot on its heels on euro op, hard to discount that possibilty given fast Pac flow, I eas excited to see the cold air settle in but that southern slider and block to our north reminds me of the last early season Carolina/VA hits that missed us.

Would think looking at that H5 with how progressive it is with kicker behind it lots are a good bit offshore with a few big monster storms that cut or hug the coast that lead to the low pressure placement there. I would like to see a bit more northern stream phase with a better ridge out west to bring a better airmass In, but you can’t have to much phase or west it goes.
