However, if I were storing cold air, I'd start it over the largest landmass in the Northern Hemisphere. Interesting stuff indeed. I agree. Also, if I were to think of a similar "harsh" December for me it would be 1983 and 1989. December 1983 was very cold and snowy start to finish. December 1989 was very interesting. It was pretty mild on the front and backend with a bitter cold snap in the middle of the month Dec 11-24. Topeka set it's all time record low of -26 on December 23 and had a high of 46 on Christmas Day. The temp had climbed 72 degrees in basically two days. 3 2 Quote 23-24 seasonal snow total: 17.8" (as of 3/9/24) Link to comment Share on other sites More sharing options...

The 1983-84 cold spells are one of the longest and harshest in Oklahoma history. January 1984's cold wave was smaller, but I joke that it's likely the reason I was born because in mid-October 1984, there I was. Lol. Must be why I like cold and snow so much. 2 1 Quote Link to comment Share on other sites More sharing options...

jaster220 Posted December 15, 2023 Report Share Posted December 15, 2023 ORD Quote Discussion: Sunday night into Monday, the storm system responsible for a rainy Saturday in the Great Lakes will phase with an unseasonably strong Gulf low near Florida, leading to the development of a powerful 975mb or so low pressure system lifting along the Atlantic Coast. Meanwhile, a secondary upper-level shortwave will dive into the Great Lakes and pull a 1030+ mb surface high pressure system in the Plains. The net effect will be a tumbling temperatures and a tightly- packed surface pressure gradient across the Mississippi River Valley. As a result, Monday looks rather unpleasant with temperatures in the upper 20s to lower 30s, blustery northwesterly winds gusting 30 to 35 mph (if not higher?), and wind chills in the teens. Tumbling 850mb temperatures will support a blossoming stratocumulus deck smack dab in the middle of the DGZ Monday afternoon, which will likely spit out flurries from time to time. Meanwhile, in northwest Indiana, water-850mb temperature differentials will grow to 12 to 13C and inversion heights will build to about 8000ft supporting a period of low-intensity lake effect snow showers. Since the upper- level wave will be compact, there will only be a 6-12 hour period supportive of snow, so accumulations will be limited (generally an inch or two, max). However, gusty northwesterly winds of 30 to 35 mph may lead to periods of markedly low visibility particularly near Lake Michigan. Looks like Monday could be a brief taste of winter for some in the MW/GL's Since moving to Detroit, it's like I've almost forgotten what a real-deal winter stretch is like.

I don't think anyone has been calling for a cold winter, let alone a "locked-in" cold winter with the Nino still raging.

I'd like to have a better understanding if this is just more "model bias" in favor of our thirst for #realdealwinter? IMO, the JMA is one of the better and more accurate LR models for Weeklies and Seasonal forecasts. Just like the Euro, it has been showing this scenario play out, as well as, the good Ol' UKIE from the UK. I'm really confident in this forecast and there isn't much pull back I'm seeing that could totally flip this scenario into a dud winter. However, those over the northern Tier of the U.S. will likely stay drier bc of the lack of a storm track due to the strong NINO (ish) STJ that is firing up. The only saving grace up north would have to be in the form of clippers or PAC waves. You will love your new place up north amigo. The lack of any ice across the GL's and the brutal cold that is coming in JAN/FEB will undoubtedly produce some legit Blitz LES. 1 1 Quote Link to comment Share on other sites More sharing options...
Black Hole Posted December 18, 2023 Report Share Posted December 18, 2023 Definitely going to continued to see an assault on the PV with a good signal for a SSW event at the end of this year or first part of January.

I have talked to a lot of old timers and obviously the 30's stands out as the worst. Some farmers I have talked about said the 50's was worse. We are currently there right now.

Black Hole Posted December 19, 2023 Report Share Posted December 19, 2023 These are from Eric Webb, who I think got them from Paul Roundy. Anyway, constructed analog for January puts a SE ridge and western trough. Should be a good pattern for winter weather in the Plains. EPS/GEFS extended seem to agree with this statistical/analog method. I think this may end up being one of the best potential stretches of winter for OK and surrounding areas. Obviously will come down to the small details we just have no idea about yet. 3 1 Quote Winter 23-24: Total Snow (3.2") Total Ice (0.2") Coldest Low: 1F Coldest High: 5F Snow Events: 0.1" Jan 5th, 0.2" Jan 9th, 1.6" Jan 14, 0.2" (ice) Jan 22, 1.3" Feb 12 Link to comment Share on other sites More sharing options...

Black Hole Posted December 19, 2023 Report Share Posted December 19, 2023 25 minutes ago, sumweatherdude said: Is it possible to tell from these maps which way the cold air would be pushed? Not definitively, but it's typically the case that the way that the warming happens can give some clues about how it will manifest at the surface down the road. SSW's main effects are that they disconnect the troposphere PV from the stratospheric one making it more free to move about and secondly, increase upper level heights in the polar regions. With that said, it does seem to me that in general the location of the stratospheric PV as it weakens and moves loosely translates down to the surface. In that sense, unless the SPV is completely destroyed its better to have whatever remains move over or close to our area. Admittedly, long range guidance seems to favor a piece over Europe and a piece over east Asia so maybe this one won't really help us...we will just have to wait and see model trends the next week or two. 1 Quote Winter 23-24: Total Snow (3.2") Total Ice (0.2") Coldest Low: 1F Coldest High: 5F Snow Events: 0.1" Jan 5th, 0.2" Jan 9th, 1.6" Jan 14, 0.2" (ice) Jan 22, 1.3" Feb 12 Link to comment Share on other sites More sharing options...
Black Hole Posted December 19, 2023 Report Share Posted December 19, 2023 Here is the Jan 2019 SSW compared to the current forecast. Not a bad match anyway. But the thing that concerns me is that the highest anomalies are right over Canada where we just can't get rid of the ridging. The atmosphere does not need an excuse to build a ridge there lol 2 Quote Winter 23-24: Total Snow (3.2") Total Ice (0.2") Coldest Low: 1F Coldest High: 5F Snow Events: 0.1" Jan 5th, 0.2" Jan 9th, 1.6" Jan 14, 0.2" (ice) Jan 22, 1.3" Feb 12 Link to comment Share on other sites More sharing options...

Grizzcoat Posted December 20, 2023 Report Share Posted December 20, 2023 Agree on the 1950's being just as bad as the 30's if not worse for drought in the Midwest. A fun fact about July in Des Moines that was up until 2012 (July 23rd at 105F) the last time a high temp was broken was 1955 (57 years). That's incredible. 4 Quote The two loudest sounds known to man: a gun that goes bang when it is supposed to go click and a gun that goes click when it is supposed to go bang.

I strongly feel the July to Sept months have greatly decreased here. We have averaged mowing each lawn 8 to 18 times. Instead of the previous 25 to 32 times, which translates into millions $$. 2 lawns east of Ottumwa we only mowed 5 times all season in 2023!!! Irrigating is nonexistent here. We do large commercial lawns. Snow has been more reliable. Another interesting tidbit is OTM hasnt had a month over 4 inches since Oct 2021!! Which mean no runoff. Streams and creeks and some ponds are totally dried up. 1 Quote Link to comment Share on other sites More sharing options...
Black Hole Posted December 20, 2023 Report Share Posted December 20, 2023 EPS zonal wind forecast was the best its been at any point this winter so far, and markedly better than what it had even yesterday. The mean zonal wind gets down to +3 m/s, very close to the reversal to easterly wind. Many members well below 0 indicating major SSW events. While this does not guarantee anything at the surface, it does increase the probability. 3 Quote Winter 23-24: Total Snow (3.2") Total Ice (0.2") Coldest Low: 1F Coldest High: 5F Snow Events: 0.1" Jan 5th, 0.2" Jan 9th, 1.6" Jan 14, 0.2" (ice) Jan 22, 1.3" Feb 12 Link to comment Share on other sites More sharing options...

Minny_Weather Posted December 21, 2023 Report Share Posted December 21, 2023 New EPS weekly run is out and it's about as terrible as expected for me. The ONLY good thing I took out of it is there is a pretty unstable stretch in mid-January that could lead to some clipper-driven moisture for me, and it would 100% be snow. Other than that, the absolute coldest I get in the entire run is seasonable warmth. Looks better for Black Hole and especially our eastern posters such as chesco.

Up_north_MI Posted December 21, 2023 Report Share Posted December 21, 2023 I had a number of friends and family ask me a couple months back my thoughts for this coming winter because they know I’m kinda into weather and trying to figure out longer range forecasts. I told them all the same thing that I expect a warm December because it’s extremely hard to have a cold December anymore and with the strong El Niño it’s going to be pretty hard to get any cold stretches at any point this winter. Unfortunately it looks like I’m going to be correct because I do enjoy cold and snow during the winter. With as strong as this El Niño was this Fall it was a pretty easy call honestly and I was pretty surprised when I saw anyone think otherwise and call for average temperatures this winter let alone colder then average. There are so many different people that put out long range forecasts on you tube and these type of forums and it’s taken me a few years of paying attention but I feel I have a pretty good idea of who to read and listen to and who not to. Long range forecasts are extremely difficult to get correct but I feel when we’re heading into a El Niño like this one it’s a pretty easy call for warmth. 2 Quote Link to comment Share on other sites More sharing options...
Black Hole Posted December 21, 2023 Report Share Posted December 21, 2023 We definitely have a window coming up from Christmas into early January down here. It's not going to be real cold so any potential storm will have to rely on steady heavy precip and a good track. 2 Quote Winter 23-24: Total Snow (3.2") Total Ice (0.2") Coldest Low: 1F Coldest High: 5F Snow Events: 0.1" Jan 5th, 0.2" Jan 9th, 1.6" Jan 14, 0.2" (ice) Jan 22, 1.3" Feb 12 Link to comment Share on other sites More sharing options...

It feels like if the avg was looked at in 2011 it would be considerably over 40" but from 2012 to now considerably under 30". I strongly feel the July to Sept months have greatly decreased here. We have averaged mowing each lawn 8 to 18 times. Instead of the previous 25 to 32 times, which translates into millions $$. 2 lawns east of Ottumwa we only mowed 5 times all season in 2023!!! Irrigating is nonexistent here. We do large commercial lawns. Snow has been more reliable. Another interesting tidbit is OTM hasnt had a month over 4 inches since Oct 2021!! Which mean no runoff. Streams and creeks and some ponds are totally dried up. So glad I passed on that job offer in Iowa, sounds like Wx Hobbiest Hell! Don't forget tho, there was a time when Hell had more snow OTG than Marquette! 1 Quote Winter 2023-24 Snow Total = 53.1" (90% Normal Season) Largest Storm: 12" (1/12-13) Oct: 0.1 Nov: 2.9 Dec: 7.5 Jan: 31.7 Feb: 6.0 Mar: 4.3 Apr: 0.1 Avg = 59.2" (Harrison): 2023-24 = 53.1" Avg = 45.0" (KDTW): 2022-23 = 33.5" 2021-22 = 35.6" Avg = 49.7" (KRMY): 2020-21 = 36.2" 2019-20 = 48.0" 2018-19 = 56.1" 2017-18 = 68.3" 2016-17 = 52" 2015-16 = 57.4" 2014-15 = 55.3" 2013-14 = 100.6" (coldest & snowiest in the modern record!) 2012-13 = 47.2" 2011-12 = 43.7" Legit Blizzards (high winds and dbl digit snows): Feb 2011, Dec 2009, Jan 2005, Dec 2000, Jan 1999, Mar 1998, Nov 1989, Jan 1982, Jan 1978, Jan 1977, Apr 1975, Mar 1973, Jan 1967, Feb 1965, Jan 1918 Link to comment Share on other sites More sharing options...
Black Hole Posted December 23, 2023 Report Share Posted December 23, 2023 GFS shoves a PV lobe over NA on its 12z run. Nice to see this since most other runs have not done this. 5 Quote Winter 23-24: Total Snow (3.2") Total Ice (0.2") Coldest Low: 1F Coldest High: 5F Snow Events: 0.1" Jan 5th, 0.2" Jan 9th, 1.6" Jan 14, 0.2" (ice) Jan 22, 1.3" Feb 12 Link to comment Share on other sites More sharing options...

It means more to show the changes from current to something prior to model fantasy timeframe to demonstrate there are substantial changes likely coming. Look at the difference between t0 and 240 hours. I don't know what the changes might mean in regards wether on the ground but it's a change nonetheless.

That's fine and all, but to anybody who knows about SSW events and what to look for, what I posted was meaningful. I've posted many maps over the last few weeks highlighting the potential. I verbally described what the difference was compared to the past runs that did not have a PV lobe over North America...etc. Lastly, there is typically much less going on in the stratosphere. It's not fantasy land at day 15 for a SSW. It's almost certainly going to happen, it's just a matter of how and where the anomalies focus at this point. But I am not going to debate with you beyond this about whether my posts could be better or not. I came on here on my own free time to share my thoughts, which have always been well-received by others, and that's good enough for me. 5 Quote Winter 23-24: Total Snow (3.2") Total Ice (0.2") Coldest Low: 1F Coldest High: 5F Snow Events: 0.1" Jan 5th, 0.2" Jan 9th, 1.6" Jan 14, 0.2" (ice) Jan 22, 1.3" Feb 12 Link to comment Share on other sites More sharing options...
Clinton Posted December 24, 2023 Report Share Posted December 24, 2023 The AO, NAO, and EPO are on their way to negative territory. Put the SSW event I would say some cold and or artic air is imminent. 5 Quote Link to comment Share on other sites More sharing options...
Clinton Posted December 24, 2023 Report Share Posted December 24, 2023 Models agreeing that the MJO will go from phase 2 into the null phase in early January. With the other teleconnections in line and the LRC it should set the southern plains, central plains and lower lakes up for some potentially nice snows between Jan 5th - 10th. Phase 1 for Dec Phase 2 for Jan. http://www.cpc.ncep.noaa.gov/products/precip/CWlink/MJO/Composites/Temperature/DJF/combined_image.png 3 1 Quote Link to comment Share on other sites More sharing options...
