The current pattern makes it even more difficult to use them. Look at the EPS forecast from 0z for +84:https://www.tropicaltidbits.com/analysis/models/eps/2022120500/eps_z500a_namer_15.png Compared to the EPS forecast for the same period but + 192 + 252https://www.tropicaltidbits.com/analysis/models/eps/2022113012/eps_z500a_namer_33.png + 252https://www.tropicaltidbits.com/analysis/models/eps/2022112800/eps_z500a_namer_43.png The PV is not caught under the block as forecasted but instead is heading into BC with a much stronger -PNA. Also the ridging is connected from the SE into Greenland resulting in a warm cutter pattern. Exactly as I warned a few weeks ago, you need the pattern shifts to move forward in time and just because the NAO is negative, doesn't mean much if a pacific airmass is trapped under the block, even for NNE. Storms cannot cut when there’s blocking this strong, the problem is the airmass sucks, and the ocean is still really warm. The earth is warmer than it used to be so more has to go right. Even a perfect track isn’t enough with the lack of cold, the low needed to deepen a lot and create its own cold air. Ridging doesn’t connect from the SE to Greenland, the block suppresses the SE ridge. NNE will still probably get lots of snow, but for the rest of us yeah the epic pattern looks like it’s going to be delayed. Honestly for those of us not in NNE the delay is good, because it means the window for the epic period is closer to peak climo when it comes. That said, the 13th threat hasn’t gone anywhere. The 10th is probably cooked though. 1 1 2 Link to comment Share on other sites More sharing options...

Snowcrazed71 Posted December 5, 2022 Share Posted December 5, 2022 So with the ECM and the GFS being in completely different camps, who do we trust and who do we lean towards. Did GFS did not do a good job with the upcoming storm for this weekend. It had it far north and now it's making its way down to meet the ECM and other guidance models. In the long run who has done a better job with the pattern, that's the question. Are we going to melt, or are we going to freeze? Can't wait to see what happens haha Link to comment Share on other sites More sharing options...

ORH_wxman Posted December 5, 2022 Share Posted December 5, 2022 GFS suite has been downright bizarre in how it handles the NAO block the past few runs. Def does not match the GEPS/EPS evolution. It's not even a block at all after about day 4-5. 2 Link to comment Share on other sites More sharing options...

GFS just disintegrates the block and never rebuilds it after Dec 10th and instead the heights fall over Greeland/Baffin and a monster ridge builds in the east. 1 Link to comment Share on other sites More sharing options...

You confident in a good pattern upcoming sir I've honestly been out of the loop with the LR for awhile...been busy with some other things. I just check in to get an idea of what's going on from the big dawgs in here. I've been peeking more myself the past few days though and it does look good, but I don't have much to add beyond what others have said. I don't usually invest too much emotionally in LR progs since they can change quite a bit come verification time. These epic d15 -NAO blocks have been fool's gold it seems during winter so I usually keep my guard up with anything in the N ATL. Basically I don't stress too much about the extended beyond d5-7. I like to roll with whatever comes and just fan the stressful flames from weenies time to time. Get the favorable pattern into that 120-144 window and I'll start paying more attention to the chances. 2 1 Link to comment Share on other sites More sharing options...

bwt3650 Posted December 5, 2022 Share Posted December 5, 2022 That was a 2015-2016 GFS run for the ski areas. It's one op run, but verbatim, there aren't even many snowmaking windows in that 360.
