     Follow-up: Today’s SOI is -10, which makes the current streak at an amazing 91 days, 2nd only to 1998’s 100 days for longest on record back to 1991. I’m predicting that tomorrow’s will be a +SOI, which would mean the streak ends at 91 days.

    As expected, today is a +SOI (+2), thus ending the -SOI streak at 91 days. Thus, the 100 day streak of 1998 is safe.

    And just like that GFS goes poof for everything. As Green Day once said, wake me up when El nino ends.

    Does the cold model forecast for this winter jive in any way with Super El Niño? Are there reasons to believe this winter season goes against the grain and produces widespread cold and snow?

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

  4.  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:

    The westerly QBO and the descending solar are two red flags for that kind of an outcome in the seasonal mean, neither of which were present in 2009....not to mention nearly 20 years of CC.

    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.

  6.  Yesterday’s NOAA weekly release for relative 3.4 came in at +1.8, which is the warmest early August on record back to 1982:
     

    29JUL2026         3.2        2.1        1.5        0.2

    05AUG2026        3.3        2.4        1.8        0.3

     ————————

    How does this compare to 1997?

    06AUG1997         3.9        2.3        1.6        0.3

    ——————

    How does this +1.8 for 3.4 compare to others for weeks centered near August 5th?

    2026 +1.8

    2023 +0.4

    2015 +1.1

    2012 +0.7

    2009 +0.4

    2006 +0.2

    2004 +0.7

    2002 +0.7

    1997 +1.6

    1993 +0.4

    1991  +0.7

    1990 +0.4

    1987 +1.2

    1986 +0.3

    1982 +1.0

     

     The earliest any of these reached +1.8 is August 20, 1997.

  8.  The image below is not only the coldest CFSv2 forecast for JFM made in summer for the SE US to C Plains part of the U.S. in El Niño, it is by a good margin THE coldest JFM forecast for this area that I could find made from any season and in any ENSO back to the start of the CFSv2 in 2012! This is extreme, folks!

     Looking at Feb, alone, the progged coldest month:

     Although the -SOI streak is up to a whopping 89 days and it will reach the low 90s (2nd longest on record back to 1991 by a large margin to early 1998’s 100 days), there’s a good chance it will finally end early next week short of the 100 day record with at least one smallish +SOI as it now appears. Let’s see what actually happens.

     Follow-up: Today’s SOI is -10, which makes the current streak at an amazing 91 days, 2nd only to 1998’s 100 days for longest on record back to 1991. I’m predicting that tomorrow’s will be a +SOI, which would mean the streak ends at 91 days.
