Here are the Georgia sites:
1) Cumberland is certainly rural: https://www.nps.gov/cuis/planyourvisit/staffordbeach.htm
2)-3) Ichauway appears quite rural, too:
https://www.jonesctr.org/about-us/
4) Colham Ferry appears to be a burb of Watkinsville, a town with only ~3K:

What do you think of these 4 as far as not having UHI to worry about?

Using NYC as an example and assuming the departures below normal being shown are correct for 3/16-3/22, what would the actual temps (highs) in degrees F be when compared to normal high temperatures in that time frame (3/16-3/22)? Just a ballpark if that verified?
~4 BN with normal based on 2006-25. Nothing drastic but the change from runs of just a few days back is what’s most notable. Also, will this getting colder trend continue?

Hmmm - well - looking at their locations https://www.ncei.noaa.gov/access/crn/ - that's not really what I'm talking about. It looks like just about all of those sites are actually suburban sites, or at least "close to city" rural sites. For example the one in central NC is in Duke Forest - but that's practically surrounded by Durham, which is a fast-growing urban area. The one in southern LA is at Cade Farm which is rural-ish, but is only 3 miles from the edge of Lafayette. The one in western VA is only 1 mile from I-64 and Charlottesville, Etc.
What I'm talking about would be truly rural sites - ones where there isn't a significant city within about 50-100 miles or so. I see very few if any sites of those that fit that bill.

That’s news to me, Anthony, even up your way:
Today’s Euro Weeklies are mild, not cold, at midmonth:
Mar 9-15: way above normal NYC
Mar 16-22: AN NYC
By golly, @MJO812may end up right for midmonth as the EW for Mar 16-22 has turned much colder (per my post 2 above this) than what it had on the day of this reply to him, Feb 26th (see quoted 2nd image)!

Euro gets to 8, no surprise its ensembles are a lot colder LR vs GFS
1 hour ago, EastonSN+ said:Yup GEFS is weaker in 8 therefore not AS cold but definitely below normal.
Reminder: phase 7 has averaged even colder than 8 in March following Niña winters as phase 8 has averaged 2nd coldest. Another reminder: as always these are merely averages of a wide array of actuals for each phase. (I use Baltimore as a rep. city to calculate these since it’s in the middle of the E coastal U.S.)
March Niña by phase (whether inside or outside COD):
1: +1.0 (near Niña Mar climo)
2: -0.1
3: +1.8
4: +0.3
5: +2.1 (2nd warmest)
6: +2.6 (warmest)
7: -1.7 (coldest)
8: -0.7 (2nd coldest)
AVG: +0.7

Nobody and no model can accurately predict the strength of Niños or Niñas the first week of March for the following winter. Anything to try to be the first and for clicks.
1. I agree that neither Eric nor anyone can possibly know at this very early stage how strong El Niño will be. It’s not that predictable and some models like the Euro have had a warm bias even all the way through summer progs. It could very well end up strong or even super-strong, but it could also end up weaker just because we and models don’t know.
2. I feel like RONI would be a more telling index to predict than ONI. RONI has recently been ~0.4C cooler. Eric may not be explicitly taking that into account. When all is said and done, there’s <100% chance (although not a whole bunch less as of now) we’ll actually have El Niño per RONI. It would be hilarious if we don’t considering this thread’s name has El Niño in it.
3. There have been some strong to super ones that were cool to cold in most of the E US lower Mid-Atlantic southward: 2009-10, 1965-6, and 1957-8. And 1911-2 was cold everywhere despite peaking at +1.4. So, even if it’s strong, don’t expect a mild winter like 2015-6 in the SE and possibly not mild also in the Mid-Atlantic. And then consider that even up at Boston that although they’ve yet on record to have a cold strong+ Nino, it could end up NN as per 1896-7, 1902-3, 1925-6, 1930-1, 1940-1, 1957-8, 1965-6, and 2009-10. That’s almost half of the 18 strong+ Ninos back to 1877-8. And 1972-3 and 1991-2 were only slightly AN vs their respective climo in Boston. A torch covering the entire E US has occurred only once, 2015-6, as 2023-4 was NN in much of the SE.-

I’ll go only B+ because of the two long torches, the weeklong holiday centered one and the late Feb one that included ridiculously warm highs of 85 and 86.
Otherwise, the consistently cold period of Jan 12th-Feb 9th was one of the most pleasurable winter periods ever experienced as a wx hobbyist. Not only was it cold, but there were also 3 weekends in a row of fascinating and unique SE winter storms to generate very enjoyable forecast discussions for full week periods in advance of each. These discussions are always made more interesting when FL is threatened like they were twice.As a big bonus, my area got 3/4” of snow. That’s 4 times the average snowfall in this area and at the 90th percentile of the area’s winter snowfall. Also, that makes two straight winters with measurable snow for the first time since 1988-9 and 1989-90.
And as an additional bonus, KSAV tied for its coldest since 2012 with 19 on Feb 1.

Today’s EW have a notably colder signal weeks 3-4 in E US vs yesterday and other recent runs. Maybe these are related to the March 4 SSWE?
EW: wk 3 (3/16-22) run 3 days ago:
Today’s wk 3: colder E US
Yesterday’s week 4 (3/23-29):
Today’s week 4: colder E US

This year’s El Niño will very likely become a strong event. Yet another series of strong westerly wind bursts over the central Pacific will trigger a new downwelling Kelvin wave that further suppresses the thermocline in the East Pacific a few months now.

The winter of 2025-6 had only 18 of its 90 days with a WPO >0. That’s the lowest # of days since the very cold winter of 1962-3, which had only 11 (lowest number of any since 1948-9). 1956-7 had only 16. So, 2025-6 had the 3rd lowest. I think 1967-8 is in 4th with 21 of its 91 days >0:

Thanks, Charlie. Don’t forget to consider a “relative” RONIlike adjustment downward. That could be ~-0.3C.

Yeah. Larry, I had been concerned we could be headed into another "dust bowl" situation as the Southern Plains has been very dry as well. That 31-32 sticks out. Could you run some numbers in the current Plains situation ? Then what we can find on the Global Indices leading up to the Dust Bowl. Hopefully the incoming Nino will derail any such evolution this time.
Hey DB,
To be efficient, I’ll look at one city, Tulsa, as a good rep of the S Plains. They actually had a NN precip fall. But winter has been dry with only 1.62” vs 5.65” 30 year normal. This was the driest winter there since 2005-6’s 1.59” and second driest on record! Records go back to 1893-4.
1931-2 winter there was wet with 7.7”. Also, Nov of 1931 is the 2nd wettest Nov on record. So, winter of 31-2 didn’t at all foretell the upcoming dust bowl. Then again, 1932 overall ended up dry overall with a very dry Feb-May and Aug-Sep. Also, 1934 and 36 were dry while 1939 was the 6th driest on record.

The current drought throughout the SE US is serious business! In my area, for example, the last 6 months’ 9.38” were in the aggregate at KSAV the driest Sept-Feb since way back in 1931-2 (though 1931-2 was much drier) and were <50% of the 1991-2020 avg of 19.74”!
Driest Sept-Feb KSAV on record:
6.52” 1931-2
6.64” 1917-8
7.78” 1901-2
9.04” 1906-7
9.06” 1889-90
9.38” 2025-6
9.44” 2001-2

WOW! 40 in your area tomorrow? 72 here in ATL area.
Hey suzook,
I don’t know if you’ve seen it but latest FFC has only ~68 in your area and only ~62 closer in to ATL due to their stronger wedged E winds for Mon’s highs. CHS has us here similar to your 68 with brisk NE winds from the wedge. But indeed, this with lots of sunshine is still a far cry from the 40s cloudy/cold rain highs in NC.

Don't know where to put this, but here it is.
New Cansips pretty sweet for next year. This is a link to December, 2026. Scrolling thru to February shows lots of blocking.
Here's a link to SSTA map starting December. Looks solid moderate Niño.
Here's a link to surface temps starting December.
Here's a link to precip starting December.
Thanks, Mitch. This thread is the perfect place.
Although we have to take this new CANSIPS run with a huge grain as @snowman19correctly reminded us, it is at least encouraging from my perspective for two reasons:
-decent chance at a much lower hurricane season ACE vs recent years in 2026
-next winter’s E US cold potential
Regarding next winter, this run for Jan 2027 is colder in practically the entire lower 48 vs the run from one year ago for Jan of 2026:
Current 2m run for Jan ‘27…N America has the largest and most intense area of BN on globe (and vs 1981-2010 to boot) and is slightly colder than last month’s run:
One year ago’s 2m run for Jan of ‘26…sig. warmer than new run for Jan ‘27:

The NOAA Feb NAO will likely come in between +0.35 and +0.60. That would easily be high enough to give us still another winter without low sunspots/not near a solar minimum without a sub -0.25 NAO as I’m projecting -0.13 to -0.20, which I’d classify as neutral. My def. of neutral is between -0.25 and +0.25.
It was headed to sub -0.25 as it was ~-0.45 winter to date as of Feb 14th, but the strong +NAO of the 2nd half of Feb raised the average. So although this was the closest call to finally stopping the non-negative NAO non-low sunspot combo streak, it appears we’ll still be able to say that the only -NAO winters since 1980 (only 6 of them) have been during sub 30 sunspot averaged winters.

EWs:
1. ~100% chance for SSWE Mar 4th
2. Last 2 runs: Week 6, Apr 6-12, is coldest week in absolutes! Not easy to do in spring!-

Today’s EW is back down to -5 for the low of the 10 mb mean wind (2nd lowest to the run of 3 days ago that had -11) and it has 100% reversing (same as run of 3 days ago) though the run still shows no sign of notable longlasting cold before April (only subtle hint for Apr 6-12 in Midwest/NE): note that I don’t base these posts on the bogus too cold especially late portion of WB extended EPS, which practically every run go to BN in most of the E US late and Rockies most of run; if one goes by those, they’ll always be thinking cold in the E US by late in the runs….ridiculous; unfortunately these too cold maps influence some pro mets @donsutherland1is aware of this problem
More on the WB cold bias issue:Today’s April 6-12 from ecmwf: a few areas 1-2F BN and that’s the coldest! This is what I mean by just subtle hints of cold:
Today’s April 6-12 from WB: the west is absolutely laughable and east is also significantly too cold! And note that this climo (1991-2020) is colder climo than ecmwf, which uses just the last 20 years meaning that alone should make the WB maps a little warmer rather than significantly colder than the in-house maps!

Do you or does anyone else know how much these 4 GA locations warmed? I’d really like to know due to their supposed lack of UHI effect.
