Using my older 1951-2010 base base, that's a +0.66C reading in Nino 3.4 - still real weak. Until September, 1992 was easily the top match in Nino 3.4 since 1950. Starting January, 1993 should become a pretty good match once again going by surface and subsurface readings in Nino 3.4.

raindancewx Posted January 4, 2020 Share Posted January 4, 2020 Long term, the Fall transitioned from a pretty canonical El Nino Modoki event - very warm Nino 4, cold by Indonesia & Peru, to kind of a mess. Anomalies below are 1951-2010 basis. December featured a very warm Nino 4 and a very warm Nino 1.2, with the heat skipping Nino 3/3.4 to some extent as a cold wave below the surface moved east. It's amusing to see 1953, 2003, 2004 among the top six matches to OND 2019 - I had experimented with using that exact blend for winter. You'd have certainly have the heat in the Plains that exists now, with the NE & SW relatively average. I didn't use it because I don't think it will hold the whole winter. That blend gets you the huge heat waves in the Summer (2003), a fairly high ACE value (2004), El Nino winter SSTs after El Nino (all), and fairly low solar with a Neutral PDO, and warm AMO. That blend with one or two other hot SE years thrown in will probably end up pretty close given how hot it has been outside the mountains of New England & the Southwest to date. I did use 1953 in my winter blend, but I substituted 2004 for 1992 since it had been the top objective Nino 3.4 match for Spring/Summer in 2019 by a country mile. The January pattern forecast looks more like January 1993 than January 2005 anyway. Link to comment Share on other sites More sharing options...

raindancewx Posted January 7, 2020 Share Posted January 7, 2020 If you use 1951-2010 as the baseline, on average, Nino 3.4 will warm 0.2C from January to February. La Ninas typically weaken late Winter and Spring, so they warm more than 0.2C. El Ninos typically weaken late Winter and Spring, so they typically warm less than 0.2C because they are cooling/weakening. Last year, Nino 3.4 warmed from January to February by 0.28C - that is much more like a weakening La Nina. Now, look at the composite for an extra 0.1C of warming above the 0.2C average (i.e. a weakening La Nina reverting to Neutral), and look at the composite for at least 0.1C less warming than average: The map on the left is the ten most recent years that warmed at least 0.3C from Jan to Feb - typically La Ninas, but also 2019 which warmed 0.28C. Now...look at February 2019: It is an exaggerated, extreme version of the left map. I think it's all but guaranteed that Nino 3.4 finishes warmer in January than December. It's not a guarantee that February finishes 0.3C or more warmer than January - but I think it's pretty likely - remember 0.2C is how much warmer February is "typically", so you only need an extra 0.1C. 1 Link to comment Share on other sites More sharing options...

raindancewx Posted January 8, 2020 Share Posted January 8, 2020 MJO currently looks like it could move back into phase four/five later in the month or in February. The high amplitude 4/5 call was depicted by late December, so it's likely the weakening phase five call is right - beyond that in late January...we'll see.

raindancewx Posted January 16, 2020 Share Posted January 16, 2020 Winter Weather Advisory for me means Albuquerque should be ahead of the combined snow total for NYC, Philly, Baltimore & DC again if the advisory verifies. Currently pretty close - 4.6" v. 5.0". The new Jamstec has El Nino / near El Nino conditions lasting for another full year, with an extremely hot Spring for the US. The ideal El Nino Modoki look in Sep-October for severe eastern cold has crashed pretty hard since, which coincides well with the rapid warm up in the East since the severely cold start to November.

raindancewx Posted January 17, 2020 Share Posted January 17, 2020 I think this El Nino may last deep into 2020, and then turn into a La Nina that peaks late in winter 2020-21 or early in Spring 2021. I'm expecting the cold water below the surface to end the El Nino from West to East, meaning we'll have Modoki La Nina / East-based El Nino forcing for a time later in 2020 (colder Nino 4, warmer Nino 3.4/1.2) Link to comment Share on other sites More sharing options...

The western subsurface does look pretty cold, so the models showing +0.5C to +0.8C in Nino 3.4 through Feb/Mar and then a La Nina next winter are probably right. I'm fairly confident that the periods of extreme Eastern warmth in the Fall/Winter are going to show up again in the Spring. Will be interesting to see how that evolves. I'll link my Spring Forecast here around February 10th if anyone is curious. Winter to date has looked a lot like 1953-54, 2003-04, 2004-05 as a blend warmed up a degree, with the heat core somewhat SE, and it's not a bad SST match either in the Nino zones. 1 Link to comment Share on other sites More sharing options...
raindancewx Posted January 22, 2020 Share Posted January 22, 2020 Not structured the same as last year, but looks like an El Nino to me.

raindancewx Posted January 23, 2020 Share Posted January 23, 2020 My January outlook from October is actually starting to look pretty good nationally. East probably won't finish +6 to +12 by the end of the month, and the Northern Plains will warm up some, it looks pretty warm from Montana to Michigan over the rest of the month. General idea from me was weak cold Plains and West in January, warm elsewhere. If you add 2F to my blend, it should end up pretty close to the final January look. My NAO indicator, and the growing model consensus of the MJO starting February in phase 5/6, not to mention the super +AO in January, all point to another warm month for the East. I don't expect the Montana anomalies to finish 10-25 below normal for the month though, if the cold goes into the West again. With Nino 3.4 not really warming up at the surface in January, but lots of warmth below the surface, I'd expect Nino 3.4 to be much warmer in February than in January, which is atypical in an El Nino. So some kind of western / central cold dump is likely if Nino 3.4 sees a big jump, like last year. The 3.5 month lag that had mid-Aug to mid-Sept fairly similar to December still seems to be working, which implies a pretty cold February for the Plains, or an area near the Plains. Here is Sept 16-Oct 5 v. Jan 1-20. There's essentially been a clockwise rotation centered on the Canadian Plains of some of the East Canada Fall warmth into New England, while the cold centered on Reno, NV shifted up to Western Canada. Very curious to see if there is any resemblance in February to this. My hunch is there will be, but it will be shifted to the northwest from the Fall.

raindancewx Posted January 28, 2020 Share Posted January 28, 2020 Subsurface is still warm, but looks like it will rapidly cool from mid-February or March on. Similar thing happened in Nov-Dec, coinciding well with the big Eastern US warm up. I'd expect a pretty warm April nationally if I have the timing right on the warm up to cool down. Long-term, a warm Spring in Nino 3.4 is a warm signal for the US in July-Sept. Last March-May was 7th warmest since 1950 in Nino 3.4. So a cooler Nino 3.4 favors somewhat less heat in that period.

UniversesBelowNormal Posted February 6, 2020 Share Posted February 6, 2020 looks like an El Nino is developing for 2020 as per the subsurface.. Link to comment Share on other sites More sharing options...
raindancewx Posted February 7, 2020 Share Posted February 7, 2020 If an El Nino is to develop again for winter 2020-21, that's pretty rare historically. Only cases I know of for a 27C or warmer Nino 3.4, three times in a row, in the past 100 years: 1939-40, 1940-41, 1941-42 2002-03, 2003-04, 2004-05 (and here you have to fudge 2003-04 - it's right at like 26.96C or so). The early 1990s are kind of an interesting case, since 1992-93 was not 27.0C, but came after a volcanic eruption that cooled the Earth, and so you had essentially an El Nino without Nino 3.4 warm in 1992-93.

raindancewx Posted February 8, 2020 Share Posted February 8, 2020 The Nate Mantua/JISAO PDO isn't in yet, but the NOAA version of it is, and shows a big crash for January. The JISAO PDO usually moves in a similar way to the NOAA PDO, but with higher values. https://www.ncdc.noaa.gov/teleconnections/pdo/ 201910 -0.96 201911 -0.28 201912 0.01 202001 -1.17 1 Link to comment Share on other sites More sharing options...

That’s probably a sign that things are changing in the Pacific. 2 Link to comment Share on other sites More sharing options...
andyhb Posted February 10, 2020 Share Posted February 10, 2020 JISAO PDO is no longer being updated. Also, the +AO has reached an all time record daily value at 6.34, surpassing 2/26/90 at 5.91. Link to comment Share on other sites More sharing options...

Nate Mantua sent me this a while ago and it's the same data as before through December 2019. https://oceanview.pfeg.noaa.gov/erddap/tabledap/cciea_OC_PDO.htmlTable?time,PDO Big drop on the weekly data. But the subsurface 100-180W is still warm and warming. Nino 3 as the coldest anomaly is unusual. We're in like an El Nino sandwich, warm edges, cold middle.

raindancewx Posted February 11, 2020 Share Posted February 11, 2020 I've been fairly impressed with 1953-54, 1992-93, 2004-05, 2018-19 for recent ocean/solar/weather conditions in the US. Had used three of those years in my winter forecast - it's the other three that screwed me up. With some adjustments for the record +AO, warmer oceans, and warming subsurface, I used that blend for my Spring forecast: https://www.scribd.com/document/446483878/Spring-2020-Outlook 1 Link to comment Share on other sites More sharing options...
