    00z GFS continues with an extremely impressive blocking pattern in the long range. By the end of the run has TWO closed upper highs in Canada/Greenland with the PV basically trapped over the Great Lakes. Given support from the GEFS and the Euro/EPS this is about as encouraging a sign as one can get for cold/snow at lower latitudes, especially if we can keep this blockiness into December. 

    Yes. Going to be hard to see a late fall pattern better than that. When retrogression begins,....  boom. This winter could be pretty historic. Too many dominoes falling in a row for it not to. Looking forward to writing about a lot of exciting weather this winter. Really haven't had much weather to write about around here in nearly 3 years.

    Building consensus for a period of increased blocking in the 7+ day range. Currently the position of the block looks to focus the core of the cold to our east but overall I’d say blocking showing up is a good sign heading into winter. Definitely a completely different look than the past couple Novembers.

    We're heading into a pretty good spot for being November. Hoping for a bit of retrogression after this pattern sets up.

    I'm somewhat familiar with ONI/PDO/AMO/Solar values for years before 1950, but I generally forbid myself from using anything before 1931 because there is no snow data for where I live, so its kind of pointless to look at for me. But I did want to ask you...what do you like about 1917-18?

    N. Pac configuration and solar mostly. It was a strong La Nina but it fits an overall pattern of years similar to 2010-11, 1988-89 also. There's some huge potential for major pattern amplification and blocking once we get a little way into winter and all throughout the rest of it. That also shares the characteristics of 1917-18.

    I dunno if the "snow" anomalies I'm linking include sleet/freezing rain, etc, but this forum region did pretty well in terms of snow anomalies in a lot of the winters I like. If SSTs mean anything, its a good sign, since the blend is very close to current conditions.

    Sanity check for analogs in Oct of analog year v. Oct 22 2017:

    Looks like I would have gotten snow in about two of those really. Talk about winters of being one county away from the fun. Yikes!

    I want to see what the AMO value for September was, but pending a sudden warm up / cool down from the hurricanes, I like a blend of 1932, 1943, 1944, 1996, 2005, 2007, 2008, 2012 for the winter. Tried to pick warm/neutral AMO years, with a mix of positive PDO/negative PDO years, low solar, La Ninas or Cold Neutrals after La Ninas, similar values to what I expect on the Jamstec's Modoki index which goes back to 1870. Also try to blend it all in a way that matches Summer rainfall patterns here, since we get so little rain even in the wet season.

    Weighting is something like:

    1932: x3

    1943: x2

    1944: x3

    1996: x3

    2005: x3

    2007: x3

    2008: x2

    2012: x1

    I think it's a much colder, but still not particularly cold winter for much of interior South, South Central, and SW US. 1932-33 was one of the winters that triggered the Dustbowl so hoping it isn't that dry, but with a VEI6 volcano in the tropics, and a hurricane hitting SW FL, a four hitting Puerto Rico & TX, something is similar - whether its Nino 3.4, trade winds, or the Atlantic, its not like Puerto Rico & TX have both been hit by fours in the same year in any other year since 1850. 

    I'm almost done writing my winter outlook, will put it out sometime between 10/7 and 10/15. Want to see how much rain we have in Oct and a couple other minor things.

    I'm looking forward to it. I'm still working and waiting on a few things to happen also before I write my thoughts out. Things are looking good for my area, in my opinion. The next 2 weeks are very critical in the overall long term pattern. Trades burst looks to cool ENSO back down. Something to keep in mind also, +AAM, -QBO, and a climbing PDO all argue for a -AO and a period of at least some cold for a large portion of the US this winter.
