There’s a lot of bipartisan chatter again about making DST year-round like they tried in 1974. That was a failure due to morning darkness leading to school children being killed. So, they prematurely terminated the experiment:

 The reason I’m posting about it here is because that would unfortunately mean all wx models coming out an hour later than they would during standard time in winter. Can you say 2AM 0Z Euro in winter? That would be absolutely horrible. 

The president, once again, calls for year-round daylight saving time

Joe Gatling, a golfer and a gardener, favors year-round Daylight Saving Time. “This would give me more opportunities … in golf [and] gardening]that is a little bit longer, so I’ll go for it,” said Gatling.

This 72 hour map shows how well much of N ATL metro did as well as much of E GA (not my area), NW 1/2 of SC, part of NC foothills/mtns and E Carolinas, portions of E TN, and some of N AL. It also shows the shaft for the immediate RDU corridor although their best 24 hour period was just prior to this as posted earlier:

More on the BoM warm bias: We remember how bad it was in 2023. But also: only 2 weeks ago, it had ~+1.15C for May (see image below) vs the latest’s only ~+0.55C in the image I posted in the previous post! It’s been doing this for 2 months and that’s the kind of thing it kept doing in 2023. We’re still likely headed for a super-Nino, but very likely not as warm as the RONI based ~+3.0C 3 month average super-super Nino the BoM is showing. It could easily be 0.5C too warm based on April/May and based on it being ~0.75C too warm based on forecasts from around this point in 2023:

The latest weekly BoM, which just extended to Nov for the first time, is forecasting a +2.9C RONI in SON. The record back to 1950 is +2.5C (1982). However, caution on the ultimate strength is advised due to warm bias as it’s been significantly too warm in April and May:

 I got just a T the last 24 hours and am at only ~1.5” MTD with most of that falling 23 days ago!

A band from Carrollton to Gainesville, which includes much of the N ATL metro, as well as to the N and NE of AHN centered on Madison county, did quite well the last 24 hours. As the map shows, some other areas of N GA, including near Rome, also did well:

And Sunday was supposed to be the best chance lol. 

Parts of Johnston county have been the RDU metro jackpot winners of the last 96 hours overall with 1.5”-2”. Here’s the last 24 hours: only they got significant amounts

Today’s Euro Weekly for May 25-31 is even wetter in the SE and is close to the wettest on the entire globe for that week for land areas in terms of anomalies!

 This has a max of 3.5-4” over N GA/far NW SC and 2”+ for just about the entire SE, just what the drought doc ordered!

not sure about the resolution of this CPC product, nor therein ...how well it reflects the real physical state out there but this looks like the deeper warm plume's slightly shrinking 

 

 That’s consistent with this that shows a fairly modest drop over the last few weeks to ~+2.0, which I assume is just temporary before a resumption of the warming: (I believe this is based on the avg for the top 300 meters)

We’ve had 0.58” total here (0.51”, 0.07”, TR)  keep seeing these 3-7” amounts in upstate and Charlotte 

 I’d love to have had 0.58” as I’ve had only a T total the last 3 days, which includes a T late yesterday afternoon and another T early this afternoon. After a beautiful 1.2” 18 hour long soaking rain on May 2nd, my area has been getting teased since with only ~0.25” total. But I remain optimistic for the upcoming week.

Last 3 days rainfall RDU metro area per Cocorahs reports for 24 hr periods ending ~7AM:

5/21-2: solid/best 24 hr period of last 3 overall with 0.5-1.5” for many

5/22-3: Johnston, SW Nash, S Franklin, and far N/SE Wake counties another good one for many with ok to quite good (0.3-1.25”) but W Wake, Durham, and NE Chatham <0.1”

5/23-4: widespread but only very light with heaviest only 0.06”/lightest of the 3 periods overall

 Maybe I‘m forgetting, but I don’t recall seeing even a drop of rain here since at least May 13th that is until just now. I finally got a few drops (a T) a little while ago and radar suggests I could get some more. But prospects aren’t great for much more this evening. Regardless, things are looking up for the next couple of days and much of the week to come with an overall wet pattern.

 I’m at only ~1.5” MTD. Thus, I had recently resumed watering regularly.

 Euro Weeklies are still quite wet in the SE next week (5/25-31) as this represents 2-3” for many:

 Good news thanks to El Nino for folks like me who prefer a not so active season and thus less risk of destruction in the SE and thus lower stress:

NOAA's outlook for the 2026 Atlantic Hurricane Season indicates that a below-normal season is the most likely outcome, with moderate chances for a near-normal season, and low probabilities that the season could be above-normal. The outlook calls for a 55% chance for a below-normal season, a 35% chance of a near-normal season, and only a 10% chance for an above-normal season. See the NOAA definitions of above-, near-, and below-normal seasons for more information. 

The 2026 outlook calls for a 70% probability for each of the following ranges of activity:

8-14 Named Storms

3-6 Hurricanes

1-3 Major Hurricanes

Accumulated Cyclone Energy (ACE) range of 45-115% of the median

———————

 It’s all relative though and unfortunately the midpoints of 11 NS/4.5 H/2 MH can still be devastating if land is affected as it takes only one like in ‘92.
 
 Also, NOAA has wide spreads. I’m leaning to lower half of these due to how strong El Niño is expected to be and not as warm ATL tropics as in ‘23.

Hey Larry. I am aware of the Main Tropical thread, but personally I don't post or get involved in those board wide threads anymore. My focus is purely local and regional and I was wondering if there's interest with any other like minded folks in the SE Region. 

 Steve, I understand your focus. There’s nothing stopping you from creating it. But,

 1. The local/regional specifics have been taken care of by SE individual storm threads and even then participation wasn’t better than the main indiv. storm thread. Even SE folks often posted more in the main trop. indiv. storm threads. For example, the Milton SE thread here (link below) had barely any posts other than Kayman’s many tornado posts due to lack of enough interest despite its major effects on FL while the main Milton thread had over 2K posts:

2. Even without a specific storm, you, me, and others can already post about the tropics’ potential effects on the SE within the SE Mid-long range discussion threads as I’ve done before. At this time of year with not as much interest in those threads vs winter, the mid-long range threads can use more posts.

3. I don’t think it’s good to create more threads than necessary because it makes the already existing threads quieter. This BB used to thrive on general threads that all would feel welcome to post in. Now it’s become much more regional. But there still is one general thread per year (titled with ENSO) and one general ATL tropical thread that both welcome all to post in.

Moderate rain with thunder. 

I'd like you folks input on starting our own SE Region Tropical thread. I know how much trauma Helene brought to our Mountain neighbors. My primary weather focus has always been tropical going up along the Upper Texas Coast. The SE Region covers a tremendous amount of Coastline from Mississippi to the Outer Banks. El Ninos tend to throw a curveball or two not far offshore. If you think the SE posters would participate, let me know.

Hey Steve,

IMO it’s not needed because:

-An ATL trop. thread already exists each year, with a big increase in posts when the SE is threatened:

-When there are specific storm threats to the SE, I’ve started threads on those storms in SE region and probably would again if nobody else does. But even then, there were more posts in the main thread as tropical posts here were kind of limited.

-So, I don't think a 2nd general trop thread is needed here. I suggest posting in the general thread and then also in any individual storm SE threat if they’re created.

Last 3 24 hr periods of rain ending 7AM at Cocorahs reporting stations (Clayton Cty has no stations evidently): many ATL area spots already got a much needed 0.4-0.8” with more to come next few days

I checked the radar and saw them doing the split around you

E ATL burbs doing quite well though.

Does anyone have a link to radar estimated rainfall?

The most solid Nino support from AAM yet if this CFS prog is to be believed:

1982-83 was hands down the worst winter of the strong nino bunch here. 

1957-8, 1972-3, and 1982-3 had the most wintry precipitation of the super Ninos in the SE US. Also, 1957-8 was cold vs the NN of 72-3 and 82-3. 65-6 was also cold.

What is the site for the daily PDO readings? I can’t remember what it is. 

Click on 2nd chart on right at this link:

https://s2s.worldclimateservice.com/climatepanel/

It dropped to -1.04, which is equivalent to the NOAA being in the ~-1.75 to -2 range.

Opinions on N half of ATL metro over next 4 days…should just about everyone expect 1-3”?

Correct. Out of all the “recent” super El Niños (1972, 1982, 1997, 2015), *at the current point in time*, 2026 is most similar to 1997

Thanks. Actually at the current point in time, I have 2026 to be most similar to 2015: check this out

13MAY2015         1.3        0.7        0.6        0.7
 20MAY2015         1.3        0.5        0.5        0.8

13MAY2026         1.3        0.6        0.5        0.6

1982 wasn't W based. That one topped out at +4.6 on Nino 1+2, which is even higher than 1997 (4.1). If anything, 1982 should be E based.

82-83 peaks

Nino 1+2: 4.6        

Nino 3: 2.9

Nino 3.4: 2.9

Nino 4: 1.3

97-98 peaks

Nino 1+2: 4.1

Nino 3: 3.3

Nino 3.4: 2.2

Nino 4: 1.1

 I didn’t say 1982 was W based overall. I was specifically referring to the mid May snapshot, when it was actually W based. I said, “In mid May vs 2026”, 1982 was more W based than 2026:

1982: 1+2 was coolest in mid May

12MAY1982        -0.6        0.5        0.4        0.7
 19MAY1982        -0.4        1.0        1.1        1.1

2026: 1+2 is warmest in mid May

13MAY2026         1.3        0.6        0.5        0.6

 So, as of mid May, 1982 was more W based than 2026. Later (July and beyond), I agree that 1982 clearly transitioned to E based. But my post was referring only to the snapshot as of the current point in time, mid May.

Darwin’s higher than normal SLP is finally starting to contribute to a -SOI. Until yesterday, it’s been mainly due to low Tahiti SLP.
