CAPE Posted December 13 Share Posted December 13 Need to see a stronger overall signal on the ensembles over the next few cycles. GEFS is the closest right now with a handful of hits and near hits. Link to comment Share on other sites More sharing options...

Terpeast Posted December 13 Author Share Posted December 13 Ensembles show signs of aleutian low retrograding at the end of their runs, bringing more cold air back into our source regions (it’ll get mild locally for a bit) 5 Link to comment Share on other sites More sharing options...

The energy dropping in behind with colder air coming in is the one to keep an eye on. Precip from that looks light/offshore for the most part on the means. 1 Link to comment Share on other sites More sharing options...

psuhoffman Posted December 13 Share Posted December 13 7 hours ago, cbmclean said: I certainly get why it is disturbing to see the eastern CONUS warm in that scenario, but isn't it expected for a strong -EPO to torch our source regions, with the huge ridge there and all? Again I'm not saying that it is not an ugly look, but I would not necessarily have keyed on the warmth in NW Canada. 37 minutes ago, Terpeast said: If canada is gonna torch, I rather it be NW canada than SE canada The thermal distribution isn’t the issue. That’s general profile is what to expect with a strong -EPO. The issue is the degree of the anomaly. It’s ok if western and central Canada are +3 or +5 but when it’s +10 or more we’ve seen recently that even when we get a favorable long wave configuration the air masses here just aren’t cold enough because our source regions are torched. Southeast Canada isn’t super warm yet but roll that day 15 forward 5 days and it would be. it’s way too far out to worry about the specifics I was just trying to point out that we’ve blamed the hostile pac of the last 8 years for our source regions being torched several times. But there we have the opposite pacific long wave pattern and it’s a similar result. 1 Link to comment Share on other sites More sharing options...

Well, its December and an el nino longwave pattern for Decembers tend to be warm. i just hope that the mid-lat atmosphere doesn’t flip Nina in January and maintains a torch pattern the rest of the winter. That’s the worst case scenario 2 Link to comment Share on other sites More sharing options...

Guidance has repeatedly been adjusting colder at shorter lead times for the eastern conus with more -EPO and less of that rollover ridge. 12 1 2 Link to comment Share on other sites More sharing options...

That’s the worst case scenario Just spitballin but nino hangover is making things muddy imo. We need to work through the tug of war before worrying much beyond that. I personally expected Dec to provide few chances for snow. Really hard here for early season northern stream stuff in any enso setup. That said, we've had the ingredients flying around already and guidance says that isn't changing yet. Get enough chances and you can stumble drunk into something if you try hard enough lol. Imho, Jan will feature a "hammer period" with cold and snow but it will primarily be NS driven (stating obvious) so my gut says a chaotic take what you can get versus tracking an actual big storm pattern. So far things have been moving along pretty close to what I was thinking in the fall. 11 1 2 Link to comment Share on other sites More sharing options...

NS = Northern stream Meaning that he doesn't expect much southern stream involvement like energy ejecting out of the SW region. Instead, clippers and little impulses in the northern stream - and getting them to dig and time up to pass south of our latitude (hopefully). 1 Link to comment Share on other sites More sharing options...

Terpeast Posted December 13 Author Share Posted December 13 Really not a fan of 93-94. We may have gotten a lot of record cold, but it really isn't a snowy pattern. Lots of mixed precip/ice with the baroclinic boundary more inland. 7 1 2 Link to comment Share on other sites More sharing options...

Yeah I was out of school a lot, but hurt myself falling on ice. Either way I don’t see this happening. Replay it now, precip will mostly be rain. Early-mid January could go either way… if the pac jet lets up a bit and allows the aleutian low to retrograde, we could get 2 week of cold. But if the trough sticks itself over AK, we torch like 2023. 1 2 1 Link to comment Share on other sites More sharing options...

I remember it well because we had just purchased replacement windows and the guy called the morning of the 21st to see if it was ok to come and replace them. 1 Link to comment Share on other sites More sharing options...
