The 6Z GFS suite is looking really stupid in being on its own including all of the main short term models in showing a snow threat in portions of C and E NC on Thu (3/12). Why is the GFS showing this?? GFS (Kuchera): GEFS mean (10:1): GEFS mean is almost all from the clueless members 4 and 14 with a small assist by 2 and 7 while the other 26 members essentially have nothing outside of the mtns:

It’s already been like summer for many in the SE on many days this month. Many are headed for one of the warmest Marches on record. I have enough summer as it is. I’d prefer March be more like a spring month. Thus, I’m looking forward to the cooldown and am hoping April overall comes in less warm than March. This has zero to do with snow.

Contributing to the problem of models looking colder further out in time is that WxBell Euro 2m Euro Weeklies maps are too cold, something I’ve emphasized in many posts. I know that @donsutherland1and Anthony are, among others, fully aware of this issue. How do I know they’re too cold? I’ve on many occasions compared the WB maps to the in-house ecmwf maps, especially in later weeks as the WB cold errors grow. The WB maps are essentially always colder and often by a significant amount in later weeks. Has anyone ever wondered why the NE US and much of W US are just about always below normal on WB during later weeks of the Weeklies? So, as the periods get closer, the WB maps more often than not warm up as the magnitude of the cold errors reduces.

Crude front month plunged 10 cents in just 25 minutes a little while ago! I wonder what happened. It’s now down 5 on the day to 86, which is an amazing $33 lower than its 119 peak just 17-18 hours ago! This is an historic day for crude oil in terms of volatility. Edit: Now I know why. I just read that Trump says the war “could” end soon. But he could say the opposite tomorrow and it go right back up. After all he only days ago said it could easily go longer than a month. It must be a nightmare to trade this and stocks due to whiplash! But that also provides opportunities if timed right due to luck. Is this a cousin to the TACO trade?

KATL’s warmest March on record is the 64.5F of 2012. That appears out of reach. However, their 2nd warmest is the 61.8 of 1945. Is it reachable? As it is now, a record warmest first 1/2 of March near 64.5 is looking likely there assuming I haven’t missed any warmer ones. But then it’s looking to cool down significantly to ~50 for 3/16-22. That would bring the MTD down to ~60 as of March 22. After that, March 23-31 would need to average above 66 to get the full March average to 61.8. That’s ~8 AN for 3/23-31. Although it isn’t looking explicitly that warm, it is looking pretty mild on the extended ensembles. So, I suppose there’d be a chance for it to end up that warm assuming models aren’t warm enough although that’s 2-3 weeks away, too far to be able to predict.

A good number of the last posts here would imho better belong in the 25-26 thread instead of 26-27. Isn’t March of ‘26 part of 25-26? And then the last post was about DJF 25-6.

IF this occurs, we’d be looking at the realistic possibility for the 2nd warmest March on record in places like Atlanta. Currently, their warmest on record is the 64.5F of 2012. That appears out of reach. However, their 2nd warmest is the 61.8 of 1945. As it is now, a record warmest first 1/2 of March near 64.5 is looking likely there assuming I haven’t missed any warmer ones. But then it’s looking to cool down significantly to ~50 for 3/16-22. That would bring the MTD down to ~60 as of March 22. Then March 23-31 would need to average 66.2 to get the full March average to 61.8. That’s ~8 AN for 3/23-31. I suppose there’d be a chance for it to be that warm although that’s 2-3 weeks away, too far to be able to predict.

6Z GEFS clown mean for St. Patrick’s Day at 10:1:

Thankfully, though the front month of crude is still up sharply from Friday (~10-11%), some sanity has returned relative to where it was at its 119 peak near 10:30PM last night as it has fallen back to the low 100s. Later months hadn’t been up nearly as sharply based on the feeling that crude won’t stay up more than a relatively short period. Once crude finally does start settling down and falling back, the ever-present challenge of retail following through will be there as they love spiking their prices quickly and reducing them back much more slowly.

This is excluding the huge rise last week, which was the largest one week rise in the history of crude futures!

Much needed heavy rain, due to drought, from a recently popped up thunderstorm now. This will also help to clean off the widespread pine pollen that’s on everything.

Purely for entertainment as this is well out into fantasyland on 12Z GFS:

-My post above yours shows that the March Euro going back to 2005 was too warm by the most in 2014 and 2017 (1.1 too warm). -2014 OHC wasn’t that warm in Feb but was in March -2017 OHC wasn’t that warm in Feb/Mar -1990, which is too far back to see model progs, had quite warm OHC in Feb/Mar (+1.1), but it didn’t lead to El Nino as it peaked at only +0.4 per ONI Edit: This shows that OHC may have at least temporarily peaked in Feb:

It might cool back to ~63-4 this evening due to the rain, but it shouldn’t get back down to 60 before midnight as it looks now.

The current record number of non-shared record highs in a single March at KATL is 3 set by two of them: 1974’s Mar 8-10 and 1907’s 20th, 22nd, and 28th. Before today, 1974 had been the only March with a current 4 non-shared record highs for Mar 7-10. Wednesday’s (3/11) high is forecasted to be close to the record of 82. So, if Wed is 83+, then 2026 would join 1974 and 1907 with 3 non-shared record highs. Stay tuned! March 1-11 of 2026 is likely headed to a record high for Mar 1-11, beating out Mar 1-11 of 1974. It’s likely going to end up near the normal for Apr 25-May 5! I may as well say that March 1-15 of 2026 is also likely headed for a record high there for March 1-15.

KATL once again had a record high today of 83, beating the daily record by 3! Tonight’s 0Z runs will be the last runs to be released during standard time. Starting with tomorrow’s 6Z runs, they’ll be released an hour later on the clock due to the switch to DST at 2AM. That won’t change back til early Nov assuming no changes in the law before then.

After a cold March 12th-13th and then a couple of days of mild, the EW are still showing ~7-8 days of BN dominant cold in the E US that ends ~Mar 23rd. After that, in the NE they show back and forth averaging NN into early April.

KATL had a record high Fri of 83, beating daily record by 3! Also, this was the earliest 83 on record.

Overall this winter for the H5 pattern, I’ve seen it missing strongly at times in both directions. Now if we’re talking 2m temperatures, WxBell maps are cold biased.

After the one cold week (3/16-22), which is still coming, an AN signal emerges like it has on prior runs in most of the E US although the NE still has just a neutral signal in today’s EW: 3/16-22: nice 3/23-29: nice (from my standpoint) is over

Saw my first wasp of the season. I love having to deal with them.

TT, My apologies for wording that as if those were your own words. That was my bad. I have no reason to refute the 0.35C rise of the last decade. 2023 had that sharp rise and that hasn’t come off with a new record likely on the way this year. But that’s just one decade and thus on its own it’s statistical credibility is much lower than that of the 0.2C of the prior 45 years. I assume you agree. I’d think that a “correction” of sorts could very well occur later this decade after the upcoming El Niño and would be surprised if the next decade were to warm close to another 0.35C. Reversion to the recent mean decadal increase unless for some unknown reason the true underlying mean increase has suddenly risen.
