Why would anyone think a 10-15 day ensemble of anything has good confidence The gfs op hasn’t led the way with anything, it has been all over the place. Lows can’t ram into a massive block, the GFS is acting like the blocking doesn’t exist and keeps cutting the lows to Wisconsin, garbage model. 1 Link to comment Share on other sites More sharing options...

They can certainly cut into Wisconsin and then they try and redevelop late . Look at the 500mb heights and anomalies on 0z gfs at hour 150-200. There is a reason it shows it cutting . Loom what the gefs did with the block for days 7-10 compared to a few days ago . It’s wild Link to comment Share on other sites More sharing options...

George-get ahold of yourself and try to remember what you've learned from being on these boards for the past 2-3 years. NAO is not be all end all. See last December for proof. GFS has performed better vs euro in recent weeks. Canadian is a shitty model period. qq omega implied the block would hook up with the SE ridge. He was correct in that regard. Eventually the block should orient to actually NOT allow storms to cut west but we're not there obviously. Keep your eye on the western US and hope for ridging. And as ScottN (coastalwx) mentioned a few days ago, orientation of the block in the north atlantic makes a difference. Link to comment Share on other sites More sharing options...

Yeah I just looked at the 500 mb apparently the blocking weakens and expands south over the US. That’s strange, the other models don’t have it though. If that did happen I would think the storm would be suppressed if anything due to how far south the block is. Link to comment Share on other sites More sharing options...

Ya it really shows up as early as hour 144 with the shift south in the blocking as it weakens over and west of Greenland and moved considerably south and that is day 6 Link to comment Share on other sites More sharing options...

The block is a block due to high H5 heights. If those heights merge with similar heights in the SE, it kind of encourages a stronger RNA and blocks cold and snow from getting here. 1 Link to comment Share on other sites More sharing options...
STILL N OF PIKE Posted December 6, 2022 Share Posted December 6, 2022 Regarding the Blocking differences Over days 5-9 between 12z eps and gefs At 0z You can see the small difference in the way the 0z gefs And the 12z eps handle the eastern flank of some lower hieghts at 500mb rotating north Thru Hudson Bay as early as hour 84-96 and how the GFS almost allows that area of lower heights to bleed East toward Greenland over the next day and weaken the blocking over Greenland significantly and the block sort of re-establishes itself weaker well South west over S Hudson Bay almost . where as the euro has that same hint of slightly lower heights rotating up thru Hudson Bay at hour 84 and after but it **doesn’t then bleed East and significantly weaken the block over Greenland** Over the subsequent couple days (like the gfs) and that hint of lower heights just sort of fills a bit and ya the block backs SW a tad bot nowhere need as far Southwest as the GFS https://www.tropicaltidbits.com/analysis/models/?model=eps®ion=namer&pkg=z500a&runtime=2022120518&fh=18 And in case anyone is wondering the GEPS shifted a tad south with its blocking on 0z Run for the above mentioned time period . lowered heights over Greenland for that day 6.5 period when comparing to the 12z run And is sort of a blend of gefs/ eps But trended south with the block more toward gefs a bit 1 Link to comment Share on other sites More sharing options...

Eventually the block should orient to actually NOT allow storms to cut west but we're not there obviously. The gfs got worse since the upgrade, it’s been shifting thousands of miles every run. The Euro has struggled with the pattern as well but not to that extent. Since when did blocks hook up with SE ridges? Aren’t they supposed to suppress the storm track south? If I end up being wrong and the blocking hooks up with the SE ridge, and then the low rams into the block I’ll admit it. But right now I am going to ignore the GFS and stick to looking at what the other models do. In my opinion every model is cutting the low too far inland, and I think it will turn into a Miller B as we get closer to the storm. There was a storm a couple years ago the models had cutting to Wisconsin, and then it turned into a Miller B in the mid range. That said, I do have concerns about the airmass. It is not all that cold. Link to comment Share on other sites More sharing options...

It is not all that cold. Usually they will. Because the normal NAO has lower heights SE. But if the trough is too far west, the SE ridge pumps up and actually becomes part of the (no longer working) block. This in general rarely happens but it seems to happen this year. The GFS since the upgrade is pretty unstable-I'll give you that-but all the guidance has been unstable-but the GFS has had the wildest swings. The GEFS have actually seemed to be leading the way of late. You hate to see it.... Link to comment Share on other sites More sharing options...
George001 Posted December 6, 2022 Share Posted December 6, 2022 Euro is trying for a Miller B. If the primary low was in even Chicago instead on Wisconsin that would be a lot better for us. Still plenty of time to correct that. There was a storm in mid December a few years ago that gave Chicago a blizzard, but then it redeveloped offshore and turned into a Miller B. The secondary low underwent rapid cyclogenesis, and NYC north got buried. Both Chicago and Boston got over a foot of snow from that storm, and some areas in CNE/NNE got over 3 feet of snow. 5 Link to comment Share on other sites More sharing options...
CoastalWx Posted December 6, 2022 Share Posted December 6, 2022 The nao is becoming kind of bootleg . The eps shows is really elongated and weakened as heights are knocked down from a temporary H5 trough. This is sort of what the gfs showed yesterday at 12z when everyone mocked it including me lol. You can see the height changes below. It does help form a block after day 7 or so and the pacific continues to show a very favorable look so that’s good. 1 Link to comment Share on other sites More sharing options...
CoastalWx Posted December 6, 2022 Share Posted December 6, 2022 Not sure what to make of the 12th. I think it’s voodoo but I’d still watch. Still a SWFE type deal possible on the 13-14. 1 Link to comment Share on other sites More sharing options...

Sey-Mour Snow Posted December 6, 2022 Share Posted December 6, 2022 I am liking the steady continued improvements in the EPS in the Pacific as Scott said. I wish GEFS AND GEPS would stay consistent with that regard. 5 Link to comment Share on other sites More sharing options...

Baroclinic Zone Posted December 6, 2022 Share Posted December 6, 2022 Uninspiring overnight runs for winter enthusiasts. SWFE potential around the 13th-14th but that remains to be seen with strength of primary and block. Could break either way. 1 Link to comment Share on other sites More sharing options...

The block is elongated in Greenland and then it sort of get a boost by the cutter or SWFE next week, But that occurs to the north of us. Not in agreement.That is not what was modeled even three or four days ago. It might be a different story in the interior if we can get more of a southwest flow event next week. There’s still a chance even coastal areas can get some snow, but I would obviously caution that. 1 1 Link to comment Share on other sites More sharing options...

STILL N OF PIKE Posted December 6, 2022 Share Posted December 6, 2022 The nothing has changed folks , everything as scheduled were put out to pasture . The kicking and screaming is over . It was clear at 1:30 am when I really looked at those 5H anomaly changes and toggled thru them . There were hints of this the last couple days but there was more clearly shown last nite . EPS Weren’t out yet when I fell asleep but they moved oward the others in that “bootleg “ look . Just look at the 500mb Height anomaly ( not the 5 day mean ) look to see the trend clearer The block Had morphed into something significantly differen then forecast days ago and last nite continued with more changes as heights over Greenland fell significantly on all modeling in the day 5-9 time frame Things are up in the air as they have been , unless you wanna pretend a 11-15 day look is not la la land . 1 Link to comment Share on other sites More sharing options...
