    The Aug ‘23 Jamstec was actually slightly colder than the prior two months. But to be fair, Sep and moreso Oct were colder than the Aug run before Nov warmed back up to no BN. However, even the Oct 23 run, which a number of us including me were understandably salivating over, wasn’t nearly as cold as the current run (also note how much colder is the Arctic vs 23-4): Current run (Aug):

    Not only have the last 5 Jamstec runs had cold and the coldest on the globe on land in the E US for winter, the 2023-4 winter forecast made in August was much warmer with it NN (see below). Also, this NN DJF forecast made in August of 2023 had been the coldest DJF made by Jamstec in August back to when the current records go back to, which is August of 2017! So, the following for 23-24 and today’s for 26-7 are the two coldest August runs for DJF: @bluewave

    The cold dominating a large portion of the E US and it being the coldest land area on the entire globe goes all the way back to the first Jamstec run with DJF, April! April: May: June: July: Aug:

    I wonder how cold Feb, alone, is in the E US. Also, I wonder if any individual winter months are colder than the prior run. I bet this DJF avg is incorporating a relatively mild Dec compared to Jan and especially Feb, which would mean quite a cold Feb. Note that the E US is the coldest land area throughout the world, which is also the case on other models. In addition, Alaska and W Canada are quite warm, which typically teleconnect with a cold E US.

    C Joe Bastardi calls them “ham sandwiches” . Well, Cristobal is the latest ham sandwich.

    There’s a decent chance for a record breaking long phase 6 this month. It started in phase 6 on Aug. 3rd: The latest GEFS, one of the more reliable for the MJO in the WPAC, has phase 6 through the entire run, Aug 26th, except it has it on the border of phase 5 Aug 18-20th: The EPS has it in phase 6 through 8/23: These are the longest phase 6 periods on record (back to late 1974): 6/13-30/1984 18 days 7/28-8/18/1984 22 10/6-20/1988 15 7/15-8/4/1996 21 2/25-3/10/1997 14 11/16-12/1/1998 16 7/19-8/1/2018 14 10/13-31/2022 19 1/5-21/2026 17 So, the longest phase 6 is currently the 22 days of late July-Aug of 1984 with the 2nd longest of 21 days mid July-early Aug 1996 (both near same time of year). The GEFS is suggesting the current one could reach 24+ days while the EPS has it ending up at 21 days.

    Initial WxBell Nov ‘26- Mar ‘27 forecast looks very reasonable although I’d like to see the month to month so as to see the expected large variability from early to late as I’ve just been posting about although they did say this: The bottom line is the colder part of the winter is expected to be later, rather than in December. Temps: Snowfall:

    The TW following 92L is also making some noise on the models and is now a lemon although the 0Z UKMET has it just as a TW moving similarly to 92L into the E Caribbean: 8AM TWO: Now up to 20/30:3. Eastern Tropical Atlantic:A tropical wave just offshore of the coast of west Africa is producing disorganized showers and thunderstorms. Environmental conditions are forecast to be generally conducive for some development of this system during the next several days while it moves westward or west-northwestward across the eastern and central tropical Atlantic.* Formation chance through 48 hours...low...20 percent.* Formation chance through 7 days...low...30 percent.

    Thank you for adding Feb of 1995 and especially 2007 to the list. Indeed, two more cold Febs and they both had warm Decs! So, the idea continues to be that a warm Dec, which is expected especially up north and especially what @snowman19has emphasized and which El Niño climo favors, has little to no bearing on how cold Feb could be. That imho tells me the best way to look toward this winter, looking at its prospects month to month. Models and analogs are emphasizing the prospect for a big range from warm start to cold end.

    Central Tropical Atlantic (AL92): Showers and thunderstorms are showing some signs of organization in association with a tropical wave located around 700 miles southwest of the Cabo Verde Islands. Environmental conditions are forecast to be conducive for development during the next few days, and a tropical depression will likely form within a couple of days while the system moves westward to west-northwestward across the central tropical Atlantic. * Formation chance through 48 hours...medium...60 percent. * Formation chance through 7 days...high...80 percent.

    Here’s the mean of the 9 Decembers preceding these very cold Nino Febs: like night and day! Look familiar?
  14. GaWx
    It is usually either a 3 month or a 1 month avg.

    Thanks, Chuck. The quite cold E US Nino Febs I’m aware of are 2015, 2010, 2003, 1980, 1978, 1958, 1914, 1912, 1905, 1889, and 1885.
