The good stuff doesn’t happen until well after Thanksgiving. Thanksgiving week is your classic preload with the cold dump into the west and Plains and pumps up the ridge out east. No one saying 75 to 80, but it’s not gonna be cold or anything like that at all. Will average above normal. 

my guess is that the pattern becomes better for most after the 5th

Is it really? I get it it’s an OP run he was referencing, but at 250 hrs out that EPS isn’t all that reliable either. Especially the way it’s been scoring. 

 

I agree with you on the above…I mean if we can trust the ensembles at 10 plus days out. That ain’t no given either. 

When I say way different, getting a 500 MB pattern correct versus getting a solution like a low passing just south of you to give you snow, is way different. It is much easier to show a ridge over the East Coast 11 days out on an Ensemble versus getting specific details on an area of low pressure. It’s really apples to oranges. That’s why I mean way different.

Tops I saw on cocorahs was 8.9", between Ashland and PQI.  The Fort Kent pic looks more like 6-7.

Ya think? Maybe?  I was looking at the back of the sled-behind the seat on the tunnel…that looked more like 4” to me.  Gotta be careful because that sleds seat has a slight bulge towards the middle..so that may make it look like more snow there.  But nonetheless, it was a substantial event up there.

Overall (at least 12z) the not much difference between the Euro/GFS ensembles outside of strength of key features and placement of the main anomaly centers but that is a warm look overall but can't dismiss any wedge potential like Scott said. But I don't really like the way the pattern is configured overall to elicit some big magical changes going through the first week of December. I think we'll certainly see some colder periods, like we've seen this month, but they are brief and more transient. There are multiple things we're fighting 

1) Persistent evolution of lower heights and deep troughing across the West

2) A stout subtropical ridge which is flexed into the Southeast as those troughs amplify and dig into the west

3) Even with a -NAO look at times, which helps to bring in that colder air (for a brief period) you always have to watch for connecting heights across the east. 

Maybe things break down a bit moving through the first week of December but we're going to want to see something in real time (like in 7-10 days) that is in place that will not trigger it...not the it will change because it looks better at D10 ordeal

I understood that part…and as I said, I agree. But these ensembles haven’t been anything to brag about either…so I guess that was more my point.

I think you worry too much.

that EPO isn't a waste, though. always good to have Arctic air nearby so you get a quick flip and cold source region

Yeah, that far out ensembles can be wrong, but I think that applies especially getting details like low pressure locations, etc. versus a 500 MB pattern.

 

However, I don’t think there’s anything wrong with accepting that it could be mild next week. This is your classic EPO dump that always goes out west and in the plains first, and that implies a ridge over the east. So you also have Climo on your side along with the ensemble prediction. I don’t think that is unreasonable.

It's not worry, it's analysis, assessment, and questioning. There is way too much emphasis and focus on extended range EPS signals and not enough focusing on real time observations (current state/pattern) and evolution of the short term pattern to look for those signals which may begin driving the pattern. Patterns just don't magically change and don't magically change. There are typically day-to-day nuisances which will determine how the pattern unfolds and behaves. For example, let's say forecast models were showing a drastic change say D6 or D7 (even D5)...we would be able to see in the next day or two those pieces which will be responsible for the change and determine in the short term the validity of this change instead of chasing D10 EPS means.

I would just like to see the PV more towards Hudson Bay to spread the cold a little bit further east. I think there might be a better chance for more eastern Canada cold after the 5th like you said.

Fort Kent snow probably settled some.

With CC putting early snows further out of reach, the focus should be on the holidays. See if we can get snow for Christmas. Might still have a shot there.

I guess 11, and 12, 18, and 19 and 20 , and 21 doesn’t count?

He’s lurking…not Stein…not Phil…not even Wolfie’s estranged daughter Greta…

He knows what we desire most and is hell bent on making sure it stays bottled up in Siberia. 

His heart’s an empty hole…

Would not surprise me if 12/20-1/20 is really the period where it happens and 12/1-12/20 ends up normal or not overly cold.

Well there’s usually the lag right..so that would be plausible.

Also the PNA is likely to go + in that period, at least historically I think 95% of -EPO/-PNA E QBO Decembers had a +PNA January

[HIPPYVALLEY]

Definitely a winter feel today with that wind. 

[ORH_wxman]

Been a lot of -NAO showing up even on the warmer ensemble looks. That’s a good sign though because when the PAC finally relaxes a little that will help us a lot. You can see it in some of the OP runs heading into early December….the weeklies show what happens when you keep the NAO look with a better PAC. 
 

The PAC will prob be a bit stubborn for a couple weeks so I wouldn't really get too anxious before the first week of December.
