Pattern November Knock-Out

We had nothing going for us last year. At least we got cold and snow building up in Canada this year. It only takes one good storm to make a good season.

Actually, correct me if I'm wrong, but cold built up in NW Canada last year as well... and gave the Western US a pretty good first half Winter. Then the whole Continent went warm after that.
 
This morning's EPS run is warmer than yesterday's 12z during the 2nd week of November, temperatures solidly above normal over the southeastern US thru mid month but there's some volatility especially the further north you go.

Take home message: Colder Decembers in the SE US are often preceded by -NAO stints in November.

Unfortunately, this year is showing little-no sign of that as the EPS weeklies depicted wall-to-wall +NAO for November. Now this doesnt necessarily mean that not having a -NAO in November automatically means December will be warm or vis versa, but it's a large-scale signal that's prevalent in a majority of Decembers during the preceding November and is something worth considering
 
I can’t wait for just one more cooler anything before global warming takes over and there is just no chance of having a cooler month.
 
These models have been wrong before and will be wrong again.

Predicted temps next week have inched downward.

The predicted temps ticked down one run yesterday and they've increased yet again. I don't expect the models to bust so hard that we see temps turn way below normal by mid month and the strong agreement amongst them and support from the large scale seasonal pattern only lends more confidence to their solution
 
Webber, I know u said December would be our best chance to get cold or At least seasonal. With that said, since we will apparently have +nao, are we thinking down the lines of maybe Jan or Feb now?
February by far is the most likely to observe a +NAO but it may occur in all 3 months. I anticipate more volatility and a less predominant positive regime this year vs last winter because the far North Atlantic is warmer, the QBO is easterly (favoring more MJO activity), & this NIÑA may remain east based (although that's highly uncertain), which will aid in reinforcing a low frequency pattern that's less conducive to a strong Icelandic Vortex however we will have to fight against an unfavorable interannual-interdecadal bgd state, persistence, etc... I would lean neutral to positive if anything but probably not as positive as last winter given the aforementioned reasons
 
Greetings from the mountains !!! Look what I found. I bring hope as we roll into a new month

Did Kory hack Webbers account?? All I hear is : blah, blah, warm, blah blah, torch....models coming in warmer, which I really don't get, unless we're talking about a winter storm?? What's the difference between 75-80 degrees, really? As long as it's in Nov and not Jan/Feb :)

Some were trying to allude/hint to the potential for temps to go below normal in this time frame and assumed the one run cooling trend was going to continue hence we aren't talking about just a 5 degree difference here lol, perhaps as much as 15 degrees or so had that trend continued in earnest. No Kori didn't hack my account and to be frank I don't care if you or anyone else doesn't like what I have to say about the forthcoming pattern, im not going to sit here and lie to you and gush over every single thing that supports cold and snow because that's not unbiased forecasting, that's unhinged wishcasting (which unfortunately JB et al are all too familiar with). If this means every one of my posts here are about mild weather and/or a blowtorch for the next several weeks so be it, I'd rather be right and/or actually gain forecasting experience in doing so than whoefully disappointed for no apparent reason

I agree 100% with what I bolded of yours above. That's why it was refreshing to see both JB mention the warm 2005-6 analog as well as Larry Cosgrove going quite warm and pretty snowless for this winter.

To clarify: it was a 2 run EPS cooling trend yesterday from warmer than normal to near normal that I mentioned yesterday and that you acknowledged.

Fwiw, today's 12Z Euro op run has the SE colder than normal 11/9-10 thanks to a 1038 mb NW Canada high that moves down into the Midwest though it just looks like a shortterm cooldown...again fwiw though I'll note that the 0Z Euro had a 1050 mb high doing something similar.
