John1122 Posted August 28, 2023 Share Posted August 28, 2023 All mid to long term discussion is in met fall at this point. This should carry us until Nov 20th or so, when December/winter starts showing up on models. Blah weather to begin fall, if the GFS is correct. Lingering heat that clings on like an unwelcome in-law on it. If the GFS is being it's normal, likely ridiculous self, we may be lucky. The Canadian says "what heat?" over the next 10 days. 2 Link to comment Share on other sites More sharing options...
Matthew70 Posted August 28, 2023 Share Posted August 28, 2023 Well we know the GFS is over calculating the heat. We know the Canadian is over calculating the chill. Somewhere in the middle which still is not fall! 2 Link to comment Share on other sites More sharing options...

The Euro looks like it has 2-3 days of upper 80s to lower 90s, with maybe some mid 90s for Memphis. Much better than the GFS and it's 100-105 degree stuff. The Euro looks to have 3 or so days of the heat and then it breaks down a bit. 3 1 Link to comment Share on other sites More sharing options...
John1122 Posted August 30, 2023 Author Share Posted August 30, 2023 The GFS has backed down some on it's extreme heat, not surprisingly. It's still well AN though. The Euro also has some pretty good warmth. The Canadian is more content to throw out upper 80s/around 90ish temperatures vs the mid to upper 90s the other two are tossing out. At least the 103-106 degree stuff disappeared. 2 Link to comment Share on other sites More sharing options...
Carvers Gap Posted August 30, 2023 Share Posted August 30, 2023 IDK, the GFS looks like it has some all time record highs between the 9th and 12th - 110 some locals. Not sure I believe that though. Looks like the model is dealing with pretty significant feedback issues regarding temps. Link to comment Share on other sites More sharing options...

Carvers Gap Posted August 30, 2023 Share Posted August 30, 2023 You can almost take it to the bank....when heat builds over Texas, it is going to find its way into the TN Valley whether it is summer or winter. It is coming east. Just hoping the tropics reset the pattern. There are some model solutions that bring a tropical storm back into the Virginias (maybe a ghost storm)?

I think it was at 222 or so. Either way, I'd feel comfortable betting my house that we aren't seeing 110+ in the forum area. 2 Link to comment Share on other sites More sharing options...

Your money is safe!!! One thing I am watching is whether we get another coastal about that day8-12 range and it pulls down a bunch of cooler air. The tropics are really playing havoc with modeling in the middle and long ranges. I have seen a few outlier runs during the last 24 hours that pull the ridge back west - something to watch going forward. 2 Link to comment Share on other sites More sharing options...
WishingForWarmWeather Posted August 31, 2023 Share Posted August 31, 2023 I’m definitely ready for fall weather. Tomorrow will be 79° but then low 90s for the foreseeable future. Wish I could change my username. 1 3 Link to comment Share on other sites More sharing options...

Carvers Gap Posted August 31, 2023 Share Posted August 31, 2023 The 12z GFS and GEFS do present long term hope w/ the ridge retrograding into the West. That is about 14 days out, and would effectively end summer here if legit, and produce an early fall pattern. Still warm, but not fiery furnace hot. That isn't the first run where that has shown up. It would be about right to have a cool down then followed by one last transient ridge(typical second tropical peak stuff)..... 2 Link to comment Share on other sites More sharing options...
John1122 Posted August 31, 2023 Author Share Posted August 31, 2023 It's approaching 3pm on a sunny August 31st and my AC unit hasn't kicked on today. That's hard to beat. It was 57 this morning and it's 74.8 right now. 3 Link to comment Share on other sites More sharing options...
Carvers Gap Posted August 31, 2023 Share Posted August 31, 2023 77 here in Kingsport w/ Idalia funneling lots of cool air down the eastern seaboard. Last day of August is a beaut. We may end up a fraction AN for the month. Daytime highs will finish slightly BN, but overnight lows have been warm and muggy on several occasions - creating slightly AN temps for the overall lows. Either way. Good run for August. 1 Link to comment Share on other sites More sharing options...

*Flash* Posted September 1, 2023 Share Posted September 1, 2023 I'm definitely curious how the rest of the year will pan out temp wise given the timing of ENSO's peak. Perhaps we get a taste of fall late September/early-mid October before the torch comes back rest of the way. Personally, wouldn't mind the winter heat getting out of the way early a la December 2021 before a turn to much colder. Whatever the case, yesterday couldn't have been more fitting to end this summer. The last few days in particular not only brought in a refreshing air mass but ensured suburbs outside BNA would mean out under 80° for JJA. For many, this is the first time that has happened since 2014! 1 Link to comment Share on other sites More sharing options...
*Flash* Posted September 1, 2023 Share Posted September 1, 2023 Looking at Moderate to Strong El Ninos since 1950-51. It's interesting how even the peak of the bell curve is from OND to DJF. While some of these winters were whiffs, others had plenty of memorable moments. While the sample size isn't that great, per this list, it sure seems like non-weak Niño's are like the 'Three True Outcomes' of baseball. In most seasons, you're going to either strike out or hit a home-run, while in others, you may get by with a base-loaded walk. The peak intensity and other teleconnections represent the uniques pitches you get within the box. 1 1 Link to comment Share on other sites More sharing options...

Interesting so far Yep, good find. The new, seasonal CANSIPS maps which came out today are a pretty big step towards a very warm early start to fall - torch for September and then a very slow, gradual decent back to normal by late December. JFMA looks like money at 500 and on the surface. Good to see that continue to be signaled by that model. Best pattern seems signaled for the last of Jan through mid-March. Kind of looking at Flash's list above, I am a HUGE fan of 15-16 for NE TN. NOT saying that is what is going to happen, I just like that analog year, because of how much it snowed IMBY. I think we see El Nino maybe hold through summer, and I think analogs which continue the Nino are most useful. The El Nino analogs I am most interested in are the ones which have an extended bout of La Nina just prior. You hear me reference SST gradient. That is not my idea. It is one of the guys in New England (Typhoon maybe). That gradient between the Nino and the rest of the ocean needs to be sharp - not washed out. I think we get that this year after the triple or quadruple dip Nina that we just had. And add in a falling QBO to go with that. ***Those analogs will be very few, but those are the ones we need IMHO.*** 1 2 Link to comment Share on other sites More sharing options...

While I imagine there won't be many seasons to pull from, might as well use next winter to build the sample size. I'll need to follow up; however, I want to say the last time we had three straight Moderate to Strong Nina seasons was 1998-99 to 2000-01. 2001-02 was a dud but it set the table well for the following year. 3 Link to comment Share on other sites More sharing options...
*Flash* Posted September 2, 2023 Share Posted September 2, 2023 Nice to wake up to see the ECMWF retrograding the heat ridge westward (GFS has it too but a bit further east for my liking). Will a mid-month trough verify? I hope so! Regardless, September 2023 is looking less like a 2018 or 2019 repeat. I'll take it. 3 1 Link to comment Share on other sites More sharing options...

fountainguy97 Posted September 4, 2023 Share Posted September 4, 2023 Looks like a warm week in the 80s and a few touches of 90 here and there but I see a lot of greens (50s) on the gfs on tidbits going forward! Link to comment Share on other sites More sharing options...

Carvers Gap Posted September 5, 2023 Share Posted September 5, 2023 Has summer just ended? That is the question that I have after looking at modeling during the past couple of days. Those "few straggler runs" from a few days ago which depicted the trough heading West have become more numerous. BN temps are become more prominent with each passing day beginning by Sat/Sun this weekend. 2 Link to comment Share on other sites More sharing options...

I’m definitely not complaining. Definitely could use some rain here in mid TN. Overall the days have been somewhat tolerable this holiday weekend. The evenings actually have been quite nice. Starting to get landscaping ready to plant new shrubs after removing ones that last winter killed. Yard is pretty much stalled in growing. I’m hoping winter is a surprise like this summer has been. This has been overall in my opinion a great summer. 2 Link to comment Share on other sites More sharing options...
