MO/KS/AR/OK 2019-2020 Winter Wonderland Discussion
raindancewx replied to JoMo's topic in Central/Western States
I think the NE US and Ozarks are risks for ice-storms in this winter. I also think there is a lot of snow in MO and other areas nearby this winter. You guys tend to get a lot of snow when we do in NM, and it looks good for us, and it hasn't in a while. I don't think it will be super cold personally, but it will be stormy. -
The thing that strikes me about the Euro / Jamstec runs is you rarely have +1.2 (Euro) or +1.8 (Jamstec) readings in February - the events tend to be lower if they are weak and weakening, and the super-events are still around +2 or more. The only real years like that are 1941, 1969, 1973, 1987, and most of those are double El Ninos.

MO/KS/AR/OK 2019-2020 Winter Wonderland Discussion

Thew new Jamstec run has corrected to anomalies that approach Super-Nino territory in Feb/Mar 2019. I really don't know what to make of it. The Euro went to +1.2C or so for its peak, but the Jamstec is +1.8. The look of the winter looks like my outlook - pretty severe for the SW and MO/AR etc. It looks like 1968, 1986, 1991 all peaked around Feb at +1.0 to +1.8, might have to look at those. -
I've done some research on the SOI for snowfall here. It isn't a great indicator for individual months, except a -SOI in Aug/Sept/Oct all pretty strongly favor snow in November here. High Oct-May seasonal snow, and a high single month for snow is favored with a -SOI in those months too. The NAM is bringing pretty good rainfall here Tues Night/Weds Morning, with snow for the tallest peaks.

I remain optimistic for this winter. There isn't a huge signal for extreme cold or extreme wetness here, but compared to last year, average is going to seem pretty great. My winters with <=50% of normal DJF precipitation and highs 3F or more above the long-term mean are pretty rare - 1933, 1995, 1998, 1999, 2005, 2008, 2013 and then last year. The following years, 1934, 1996, 1999, 2000, 2006, 2009, 2014 are varied, but overall, the signal is for a somewhat wet winter with average highs. Most of these years feature one fluke snow event outside Dec-Feb, Oct, Nov, Mar, Apr, May all had measurable snows. My winter last year was close to a blend of 1933-34, 1985-86, 2005-06, so tentatively looking at 1934-35, 1986-87, 2006-07 for this year.

Officially got 0.31" of rain today. That brings June 15-Sept 9 to 4.50" exactly for Albuquerque. The 1931-2017 mean for June 15-Sept 30 is 4.32". So we've had an above average monsoon here now. For June 15-Sept 9, against 1981-2010 we're about +17% now, against 1931-2017, +28%. El Nino cold seasons after a wet monsoon tend to be snowy here - (long-term snow mean is 9.6")

I've decided to roll with 1934, 1976, 1986, 1994, 1994, 2006 as my Fall analogs. Cold AMO ring, slightly positive PDO, El Nino developing, La Nina in prior winter, low-solar, similar Modoki structure, and similar Monsoon conditions. So we'll see how it does. We had near record November highs here last year (65.4F, average in Nov is 57.3F), so that is the main reason for the huge drop off expected. Going from +3.3F for Fall highs to -1.4F for Fall highs against 1951-2010 is what the analogs get for Albuquerque.

Sea Ice Extent on 8/17/18 was 5.568 million square km. That is above 2017 (5.371), 2016 (5.398), 2012 (4.691), 2011 (5.495), and 2007 (5.322) for the same date (8/17). Will be curious to see how the annualized AMO v. ice extent on 8/1 plot looks after this year is over.

As of July 21, ice extent is +0.5 million square km above last year. Math for the win.

The June AMO came in at the lowest value since 2002. https://www.esrl.noaa.gov/psd/data/correlation/amon.us.long.data AMO peak looks like it was 2005-2012, after warming a lot in 1997-2004 and near neutral for much of 1989-1996. We may be transitioning to a more Neutral AMO for 2019-2026 before the real flip to the cold phase begins. I look at 2013-2018/9 as kind of a "warm, but cooling" era. We seem to be past the era when every month is warm in the Atlantic, to where MOST months are warm, and soon it will be half, then it will be rare, and so on.

My point was more that even in areas where people supposedly care about environmentalism and global warming, they really don't. If you believe the oceans will rise 50m in the next 100 years why would you live by the ocean? I've been to Cape May County, used to go every Summer - would bet good money no parcel of land is more than 100 feet above level, and it is surrounded by water on three sides, but I'm sure some of the people who live there haven't put two and two together about the possible sea level rise. To go back on topic, the AMO has been warming up recently after the cold May/June, will be interesting to see what it looks look by mid-September. If it stays relatively cold, I don't think the min or shape in Sept of sea-ice extent looks anything like last year.

The idea that civilization can be redesigned because people care about the environment or the Earth's temperature seems kind of ridiculous to me. Liberals are supposedly the people who care about the environment, but they live in densely populated, highly urbanized areas, not just in the US but globally. I live in the West, with people who are small farmers and ranchers, where we have clean water, clean air, and can see thousands of stars every night and we kind of laugh at the idea that somehow the right is the problem. There is literally nothing stopping the Democrats from changing civilization to adapt to global warming in areas that are urban and by the ocean - that is how you know it won't happen. Los Angeles alone probably produces more smog and warming than 30+ US states if traffic is as bad as I remember.
