Do you try to educate/enlighten any of those around you who you feel are ignorant and/or stupid? After all, ignorance and stupidity can at least be partially cured through educating. It obviously is going to be harder to help those who are stupid due to lack of intelligence, which of course is genetic. Unfortunately for them, it is a difficult situation....a disability of sorts.

For the SE overall: In terms of cold, only late winter was cold. In terms of wintry precip, it was feeble at best (vs our normals of course). Charleston did get a trace of wintry precip in Feb. Don't laugh as getting ANYTHING on the SE coast is a victory for winter lovers per the climo of most winter months on the deep SE coast having zilch.

1. Based on my location and preferences, I'd rather have El Niño than neutral and there is good support for that possibility. But after being humbled in 2017 by an epic forecasting failure, when it took me (and others like JB) til July to give up on El Niño for that fall/winter, I learned more than ever before that significant uncertainty almost always exists this early in the year and will try not to bet too heavily on any one scenario until getting later in the year. 2. Location, location: - Dec 1989 was epic in terms of severe cold in the E US and especially epic in terms of a very rare coastal SE US snowstorm. - January of 2002 gave Atlanta its heaviest snow since the great blizzard of March of 1993. - Per Eric Webb's tables, the winter of 1894-5 also was a neutral winter that followed La Niña. Feb of 1895 was absolutely epic in terms of severe cold and snow in the SE US. This includes not only a place like Atlanta, which had its snowiest month and coldest Feb on record (still is), but also down all of the way to the Gulf and SE coasts. https://www.webberweather.com/ensemble-oceanic-nino-index.html 3. So as one who prefers a cold winter, I'll be glad just to lose La Niña with the hope we get El Niño.

Is the U.S. really a "nation"? Not necessarily according to this: https://www.philosophytalk.org/blog/why-america-not-nation "The short answer is that too many Americans hate, or at least really dislike other Americans for us to count as a nation."

Yeah, there hasn't been a quadruple dip LN since at least 1850 per Eric Webb's ENSO tables. So, the odds are very low for a quad dip though of course not zero. But keep in mind that neutral is quite possible as 30% of falls/winters since 1950 have been neutral, which is almost as high as the % for El Niño. Who's to say that the three in a row La Niña isn't broken with a neutral rather than El Niño? I'm not saying that I'm necessarily looking for another 2017. Rather, my point is that 2017 illustrates well the uncertainty this early despite El Niño being favored. Consider that the % chance for El Niño per the CPC is at 63%. While that's rather high for this early, it isn't even quite to a 2 in 3 chance. If they were near certain, they could have given a 90% or so chance.

Further to my prior post about the uncertainty level this early, here is a link to the March of 2017 ENSO outlook report from the Columbia University site that has model as well as official CPC probabilities: https://iri.columbia.edu/our-expertise/climate/forecasts/enso/2017-March-quick-look/ To compare, here is the link to the same issued last week: https://iri.columbia.edu/our-expertise/climate/forecasts/enso/current/ At this time in 2017, the model based probability of El Niño was way up at 68% already in JAS and 60% in NDJ. It had the chance at La Niña in NDJ (which is what actually ended up occurring) at a mere 11%. That compares to the current model based probability of El Niño at a nearly identical 67% as of JAS and an identical 60% in NDJ. The current chance for La Niña in NDJ is at 9%, which is not that much lower than 2017's 11%. The dynamic model mean peak for Nino 3.4 at this time in 2017 was during NDJ, when it was way up at +1.4. But NDJ ended up way down at -1.0! In comparison, the current dynamic model mean peak is only +1.0 and that's during SON. In 2017 at this time the models had a similar +1.1 during SON. But SON ended up down at -0.7. As I said in my prior post, I do feel El Niño is favored. But then again, I thought similarly at this time in 2017 per this 3/20/2017 post at another forum: "The weekly SST anomalies rose rather substantially in all 4 regions, including a rise of 0.5 C in 3.4. That is the largest weekly rise there in 3 years and is encouraging to me because it is an indication that El Niño will likely be here for next winter." At this time in 2017, JB was already showing El Niño winter temperature analogs to be used for 2017-8. He continued to go with El Niño well into the summer. I also maintained "very good" chance at El Niño through June. It took all of the way til July before I started backing down. So due to a high level of uncertainty this early as illustrated well by 2017, I wouldn't bet the farm on a strong El Niño or any El Niño for that matter for 2023-4 this early even though El Niño is favored (and I'd strongly prefer El Niño occur due to them overall averaging colder in the SE vs other ENSO).

Today's weekly SSTA release (based on last week) has the relatively volatile Nino 1+2 region up to +2.0 C. This +2.0 is quite notable since it is the highest in Nino 1+2 since 3/15/2017, when it was at +2.3. But oddly enough, that +2.3 was during a neutral period that followed La Niña (weak) just a few months earlier and preceded what turned out to be a moderate La Niña in 2017-8. Nino 3.4 was then at +0.2 (vs 0.0 last week) and peaked four times at only +0.5 during April-July. So, Nino 1+2 at times can be very misleading. Here is the link to the 2017 ENSO discussion thread to illustrate how deceptive things turned out to be in retrospect during March of 2017: From that thread, the first post (done in March) had this: "Lots of things to iron out over the coming months, including the infamous spring barrier forecast. But as of now we are under an El Niño watch with a 50-55% chance of an El Niño event for 2017-2018. 6 models have El Niño developing by July 2017. ENSO regions 1+2 are reading at 2.6 C, meanwhile regions 4, 3.4 remain cool." So, as of March of 2017 when Nino 1+2 was last +2.0+, the models were suggesting that there was a good (50-55%) chance for El Niño in 2017-8. To compare, we're now at ~63% chance for El Niño in 2023-4. However, the CFS changed drastically as per this post just 1.5 months later in early May: "The CFS has backed off dramatically on El Nino strength and has more of a weak Nino or even neutral conditions. Meanwhile the JAMSTEC is gung ho." And then this post from September summarized very well the drastic change in the ENSO outlook: "How can it be that we went from a good chance at an El Nino, to now a very good chance at a La Nina? Is it that unpredictable?" So, whereas I agree that El Niño is favored for 2023-4 and strong+ is quite possible, this 2017 thread illustrates well why there's still significant uncertainty this early.

Wow, that's awesome! I watched the point counterpoint videos regularly. I remember Ken (RIP) ending them saying "We are the weather warriors". I also remember Dr. Joe Sobel, Elliot Abrams, and a few others doing those videos. I especially enjoyed Dr. Joe!

Regarding the good and despite the mess he's been getting his forecasting reputation into in recent years largely due to minimizing the effect of AGW, I'll always have the utmost respect for his being a good father, husband, and family man overall (based on my perception, of course). I've had a good feel for his love of family based especially on the numerous videos I've seen. When they were little, he had both of his kids on a lot of the videos and they seemed happy most of the time and enjoying being with him. In judging the quality of a person (as much as I'm able to do), things like that far outweigh many other aspects.

The last few days of modeling has suggested to me fwiw no signs of unusual cold the next two weeks at least. Instead, it is suggesting to me more typical ups and downs with the % of time AN probably a bit higher than the % of time BN, especially down here. I'd prefer more BN overall but that's not what I'm seeing. AN is ok with me if the dewpoints are low enough...say mid 50s or lower. I mean a high of, say, 85 with a dewpoint of 52 along with a nice breeze and sunshine (like we had here for a couple of days a few days ago) feels good to me, especially if I'm in shorts.

He's often noted having "energy clients" going back many years in his free videos and on Twitter. Since many in the fossil fuel industry due to bias are often at odds with the research that shows the burning of fossil fuels as the primary reason for GW, I figure that some of them likely prefer a meteorologist who doesn't recognize that. With JB knowing that, I'm betting that he figures he'll have a better chance to hold onto these clients and get new ones with his denial of AGW.

So how did the cold CMC end up doing in comparison to the not as cold other models in the Atlanta suburbs for lows on 3/20-1? Here are the actual lows: March 20: Marietta 26, West Atlanta 27, NE Atlanta 25; so average was 26 March 21: Marietta 29, West Atlanta 28, NE Atlanta 28; so average was 28 rounded For March 20, the CMC predicted 21 while the others were 28-30 (GFS was at 30). For March 21, the CMC was at 23 vs 32-35 for the others. So, as expected, the CMC was quite a bit too cold (5 both nights). However, the others were 2-4 too warm on 3/20 and 4-7 too warm on 3/21. So, none of the models did all that great with their predictions 3-4 days before although the CMC was predictably too cold.

In his free video today, he said nothing about his NYC 5 BN/20" snow prediction for 3/1-4/15. Instead, it was dominated by his saying that SST increases over the last 40+ years may have been primarily caused by sharp increases in underwater seismic activity. Then he said that CO2 increases resulted from increased SSTs based on a two year lag after the last two superstrong El Niños as opposed to the other way around. I'm just communicating what he said. He's great at cherry picking, which is probably what he's doing here. He also said that the prime reason for a trough on the west coast/ridge east coast this winter was a "hotspot" in the N Pacific south of the Aleutians. He said that the strength of the upcoming El Niño is likely going to be dependent on how strong is the Wolf Volcano(es) activity off the west coast of South America. Evidently, JB is feeling that underwater volcanic activity may be the most important factor regarding climate change as well as for the shorter term. One thing that's likely biasing him away from the idea of fossil fuel emissions being the primary cause of GW is his having energy clients. In summary, I think he's lost it.

Don, JB sounds desperate and he's clearly not admitting to his impending major forecast failure. So now he's citing underwater volcanoes as a potential indirect main cause of GW as you've undoubtedly read: "@BigJoeBastardi · 6h 75% of volcanic activity is underwater and we know virtually nothing about it . Given that even Al Gore admits how hot the center of the earth is, would it not stand to reason that scrutiny of that input should be a major priority?" -------------- Where the heck is he getting this from? What do you know about underwater volcanoes and their effect on ocean temperatures? In trying to be as open-minded as possible to what sounds to me like BS, is there any reasonable chance that they can be having a significant effect on ocean temperatures? Is it possible for the absolutely massive volume of water in the oceans to somehow be significantly affected? I don't see it, but still want to read your feeling about this.

It is now in the low 80s here with dewpoints in the 50s, a beautiful blue sky, and notable breezes. The birds are very active as if to say spring is back. This is all making for a pleasant day to be outside. If that looks like a copy and paste from yesterday, that's because it is. Unlike yesterday though, I hope to have some time today to sit outside and take it in.

More on 1982-3: In the SE, DJF 1982-3 temperatures averaged near normal. KATL had 10.3" that season from a highly unusual four different events. No season's snowfall has exceeded that there since but there was heavier prior, including 1935-6 and the historic 1894-5. To top that off, Raleigh had 1.8" on April 18th! That was and still is their latest measurable on record, with 1989's April 11th second latest. Those are the only two measurable April events there during the last 100 years. But the prior 40 years had four Aprils with measurable at Raleigh.

No season's snowfall has exceeded that there since but there was heavier prior, including 1935-6 and the historic 1894-5. Regarding that April of 1983 latest on record JFK accumulating snow that you mentioned, Raleigh, NC, had 1.8" on the 18th from the same system. That was and still is their latest measurable on record, with 1989's April 11th second latest. Those are the only two measurable April events there during the last 100 years. But the prior 40 years had four Aprils with measurable.

On this date 40 years ago, Atlanta (the official station at the airport) received 7.9" of a very wet snow from a Miller A GOM low near the tail end of the very strong El Niño of 1982-3. The high and low that day were 47/32 with the high just after midnight preceding the snow. Nowhere near that much had been expected due to the borderline temperatures. This 7.9" is the 3rd heaviest on record in Atlanta with only late January of 1940's 8.3" at the airport (10" downtown) and mid January of 1893's 9.6" (downtown) exceeding this. For those not familiar, the airport is ~10 miles south of downtown. During the 11 days prior, KATL's lowest was 32 (and that was 11 days prior) while highs were all 51-73. We even got a trace of sleet way down here (Savannah) from this, our second latest wintry precip on record.

The new Euro weekly for 4/3-10 (Masters time) has switched from a pretty strong cold signal to a neutral signal. Actually, all of the weeks have a neutral signal.

It is now in the low 80s here with dewpoints in the 50s, a beautiful blue sky, and notable breezes. The birds are very active as if to say spring is back. This is all making for a pleasant day to be outside. If I had the time, I'd be sitting outside now to take it all in. There's no notable cold wx in sight at least down this way. It looks solidly AN til it cools to possibly a little BN near 3/28 for a couple of days.

March, specifically, was actually AN in 2020-22. The last ones BN were in 2019 and 2018, with 2018 similarly to 2023 influenced to colder by a major SSW the prior month. Despite the very cold mid month thanks to the Feb SSW/very weak SPV, March of 2023 appears to be headed to pretty close to normal rather than solidly BN because the first 10 days overall were so warm. In 2018, it turned colder a bit earlier due partially to that SSW being about 4 days earlier and less time needed to overcome the strong -PNA that had been in place. This time it took til 3 weeks after the major SSW, a bit longer than the more typical 10-14 days, again thanks to the stubborn strong -PNA that didn't give up easily. It remains to be seen whether or not a particular location's March will be colder than Feb as it will be close. But I expect at least some to be colder.

In my area, KSAV (airport) ended up with a low of 35 this morning (normal is 50). Similar to you, this was the coldest low of this airmass due to having a better radiational cooling setup vs yesterday, when the low was 36. But unlike your area, today wasn't the coldest of this month as KSAV had 34 with the prior cold period on 3/15 followed by 35 on 3/16. At KSVN (Hunter AAF), the low today was 38, which is warmer than yesterday's 36. The radiational conditions weren't quite as good as at KSAV.

As @dsaurhas alluded to, having cold during and near the Masters is common. Today's Euro weekly for 4/3-10 suggests the patrons and golfers may need to bundle up (see below). There have been eight Weeklies runs covering that week and the one issued today has by a good margin the strongest cold signal for the SE/E as the others were either neutral or favoring warmth. That week has the strongest cold signal for the SE on the run and looks to be largely -NAO influenced. Are there more frosts and even freezes on the way for much of the SE within the first 10 or so days of April? This could be another Feb SSW influenced cold period as major SSW influences sometimes last a month or longer. Stay tuned! Today's Euro weekly for 4/3-10, which is reminiscent of what many runs correctly called for the very cold week of 3/13-20:

With today's 28 at KATL being the coldest year to date, that (March 20th) sets a new record by one day for the latest coldest year to date (excluding the subsequent cold season that starts late in the year, of course). So, this is on day 79 of 2023. The old record was March 19th of 1892, though that was a leap year meaning that it was also the 79th day of that year. However, unlike today, that coldest to date on 3/19/1892 was actually a tie with 1/7/1892. By the way (this is very likely just a coincidence), the Arctic north of 80N just had their coldest day of the winter to date on March 16th.
