Just prior to Christmas. The way things are going, probably will happen. Terrible month. Either cold and dry and every warm-up is rain. Hopefully it improves after Torchmas.

I think it will - that said, I have hope that the look around xmas will improve. Tell me if I'm wrong, but the dynamics of this year's weather feels different compared to that of previous torchmasses.

Some other stuff too. Hopefully the better guidance by a long shot is wrong. I'm not sure I buy a Christmas torch here quite yet. It's because the EPO tanks and the cold plunged into Plains first.

Yea the GEFS and GEPS look better for sure. The GEFS have been doing a better job the last month or so than the EPS. Certainly no bitterly cold air in site for awhile but I think once past the 20th or so it will be much better for snow chances than the next week or 10 days.

I don't have that stats in front of me, but it seems like the euro guidance has handled this better overall. Not that you should buy it outright, but it's been decent. BTW, yesterday when I talked about Mike Vs stuff...he has a euro set of guidance for tropical forcing.  Things like 850 winds, VP200 etc. The GEFS can have a retro bias I guess with that among other things, so it typically may not handle things right. 

FWIW I like to have some fun with the all cold all the time crew. But, I always put my thoughts out....and it's not always going to paint a rosy (or should I say white) picture. I like snow more as much as anyone...but I remove that bias as best as I can when it comes to putting my thoughts out there.  I know that's not what people want to hear, but why should I twist my thought process around for that?

I respect this. And speaking for myself, if I ever am over emotional while responding to you, it’ll always be from a place of wanting to shoot the messenger.

 

that said, just finagled some views at guidance, and it looks like we get a cutter then avg temps up till Xmas with possible warm ups when it gets wet. Not the end of the world. A very “2018” winter pattern.

I'm having a hard time with CLT seeing a lot of snow. FWIW the so called snow maps on weather.us look atrocious. It's giving CLT snow with what appears to be some parts of the 850-700 column above 0C. I wonder of this is a case, of the damming resulting in more ice..or penetrating a little more south, but the warm tongues that close to the source region may need respect.

GFS really goes to town with ULL snow after the rain next weekend in CNNE.  Have to watch that.

Just because I like to think things, it would be nice if we could get some trending to at least start as snow.  No reason to think that'll happen of course, but weenie hope springs eternal

6Z Euro was colder in the column

I agree with Scooter that EPS has gotten the better of GEFS lately....after the GEFS had done better with the November cold. 

EPS was seeing this coming mild period much more consistently than GEFS. Hopefully we stay on the cold side of the gradient near Xmas but it's def possible we are pretty mild with a classic grinch cutter too because of the EPO shoving the cold air straight south to the west of us while we have no blocking support in the Atlantic.

Could December's pattern stick for the rest of winter. 

I realize pretty much everyone thinks it'll turn around in Jan or February, but is that really guaranteed.

It would pretty almost unheard of for the pattern not to flip to much colder at some point by February. Only the super ninos seem to have warm/mild the way through. Other ninos tend to flip either in January or February. 

Weaker modoki ninos are even more likely to flip and usually it's a harsher period of cold/snow too.

Well I respect Orh Wxman, and Coaster WX expert opinions on this. I am leaning more toward Isotherm's own expert opinion when he says that the EPS has a bias of overdoing geopotential heights over the East. As well as overestimating the low-magnitude MJO signal  and goes on to say that the ""GFS based guidance will once again prove superior in the LR". Another expert opinion I agree with is PB GFI as well as SnowyHibbo.

Here says 

This is the last example,  but if we ignore the models past bias we will make the same mistakes in the future.

 

The model does hit forecasts, I am not saying that but this corrected from a 500 that is a lot worse than where the negatives are now forecast in the EP on its new 11 to 15 

 

Again the problem is washing troughs out on the EC.

 

When I see the new 11 - 15 I don't buy it.

Who/how many/how long until people start saying that Will punted January?

Lol. They'd need some reading comprehension brush up...since it reads much cold by February. 

Some years like 94-95 and 06-07 were warm in January and finally flipped cold for February. But most flipped before that...like '02-'03, '04-'05 and '14-'15...'57-'58 and '65-'66 for earlier examples.

That’s a pretty good foreacast. Low heights in AK. Warmer Canada and the storm signal in the south. All going to plan. Uncle Leo, you’re only fooling yourself.

We are pretty much following the 02 03 pattern . 

I'm not totally sold on that pattern yet.  There are several weak El Nino winters that this is actually following, not just 2002/2003.  An average of them all may actually end up being more appropriate
