    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?
  4. 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.

    It’s very likely overdone, which is why I say it is more like a dream. But IF it were to actually have an inkling of what’s to come, we could be in store for an exciting or possibly even fab Feb. It is essentially going for another Feb of 1958, one of the greatest Febs on record in the E US and this with Feb RONI way up at +1.84! The CFS RONI prog for Feb ‘27 is for a rapid collapse down to +1.5. So, is it likely? No. But is it doable? Yes.

    Due to the extreme cold anomalies progged by the CFSv2, look how cold the progged CFSv2 March ‘27 SST anomalies are off the E coast and in the N Gulf! Some areas are -5C/-9F even vs the slightly colder 1984-2009 climo!

    The latest 10 day mean of CFSv2 op runs for JFM is even colder than what had very briefly just become the coldest ever CFSv2 10 day JFM mean that I had ever seen, which I posted last night! It has KATL at -3C/-5.4F vs the 1991-2020 mean. That’s 44F. For reference: since 1980 only one JFM has been 45F or lower: 2010’s 43F!

    This OISST relative 3.4 anomaly graph shows a rapid warming the prior 48 hours of ~0.2C.

    A thunderstorm started here a little before 5PM. Coming down hard! Edit: Total for 8/10: ~0.5”
  15. GaWx
    But this Nino at +1.8 is already stronger than 23-4 at its +1.5 peak. This is going to dwarf 23-4.
  16. GaWx
    This is still another model looking great leading up to a potential Fab Feb. It’s ashamed we can’t see Feb on this run.
  17. GaWx
    As expected, today is a +SOI (+2), thus ending the -SOI streak at 91 days. Thus, the 100 day streak of 1998 is safe.

    If so, Feb would seem to be the best opportunity per models and analogs with a mild Dec and in between Jan.

    Mainly for entertainment: The image below is the TT 2m mean of the last 12 CFSv2 ops for Feb ‘27. It is extremely cold from the C Plains to the SE US with anomalies of -8 to -11 F even vs 1984-2009 climo, which is a bit colder than 1991-2020! It’s just about as cold there as the frigid Febs of 1978, 1958, and 1905 and is a bit colder than Febs of 2015, 2010, 1968, 1963, 1947, and 1902. So, it is the coldest Feb there since 1978. It isn’t quite as cold as the record coldest, 1895:

    1982-3 and 2015-6 are two super strong ones with both a +QBO and descending solar fwiw. 1957-8 was a super strong with a +QBO and was barely after peak.
