    Kind of rainy, cool, very humid day here at TRI. We used to get these a lot. Nice to see them every once in a while. Heavy rains have fallen in the foothills near Greeneville as others have noted.

    Per NOAA in DJF (my def. of neutral PNA is between -0.25 and +0.25) 1. 2024-5 was, indeed, very +PNA with a whopping 72 of 90 days being +PNA vs 18 neutral PNA and zero -PNA! That’s amazing for La Niña! Going back to 1949-50, the only other DJF without a single -PNA day was 2002-3! 2. 2025-6 was actually a more typical La Niña with more -PNA than +PNA: 49 -PNA, 14 neutral PNA, and 27 +PNA. https://ftp.cpc.ncep.noaa.gov/cwlinks/norm.daily.pna.index.b500101.current.ascii

    Day 4 NSSL machine learning likes a day 4 threat and days 9, 10 and 11 as an active period. https://x.com/TylerSebreezy/status/2076303103263932677 The latest NSSL machine-learning severe probabilities highlight a potential northwest flow setup for a handful of days across the eastern U.S. The risk of some strong to severe storms appears evident at times.

    Max heat begins to move West later this week.

    We will see. I don’t deny that there could be *some* destructive interference. I’m just arguing that the event will be so strong and well-coupled that it won’t have a significant outcome that diverges from the canonical El Niño winter pattern (GOA low, strong southern stream, above normal N Tier, and wet S tier). 97-98 likely had constructive interference.

    I’d rather have the January 2008 60s with severe weather.
  8. Met1985
    Yeah we've had a lot of rain since Saturday morning. Over 2 inches here probably close to 3 inches now and up. Been a lot of water falling. Definitely putting a dent into the drought.

    You could say that this year is its own oddball so far. A record El Niño for this time of year with a still strongly -PDO with a -PDO type of North American pattern. It just makes me leery that we’re suddenly going to see a flip to 1997 across North America. No doubt much of the rest of the globe is and will continue to look very Ninoish.
  10. LakePaste25
    OLR is exactly what you’d expect in July for an E based Nino. Note the convection going north as you go east…that’s consistent with climatology this time of year due to the Humboldt current which impacts Nino 1+2.
  11. A-L-E-K
    Think we manage an mcs into the area at some point but I get the sentiment here
  12. LakePaste25
    15-16 was an oddball. Unusually strong MC forcing in december and in Jan/Feb the E Pac convection was unusually far north (failed to collapse near the equator as it’s supposed to do during winter), which actually enhanced Baja ridging as it was the descending branch of the Hadley Cell. Both of these factors helped contribute to the record warm December and the Mid Atlantic blizzard.

    This is the year. When few are expecting it with a super Nino ( except me who thinks it the year)
  14. jaxjagman
    Actually if you go back to 57-58 it was quite cold after Dec,while NOV like you mentioned was BN,Dec was more severe,but J/F was really cold,if that happens again who know,plus March of 1958 had the blizzard in the east
  15. roardog
    You would think so but even 2015-2016 seemed to have some outside influence and that was a beast of an El Niño with a strong +PDO. We can’t even sniff a +PDO this year so far and it seems the North American pattern is making sure we know that.

    I'm getting a little concerned with the repeated rounds of heavy rain. The WPC has concerns also.

    You need something to pop off the SE coast from a stalled front.
  19. roardog
    That’s the funny thing about 1997-1998. I recall there being more cold early in the winter than later in the winter which is kind of opposite what you think of with El Niño. Of course November was quite cold so there was probably quite a bit of lake effect that month. One memory for me that stands out from that winter was being on the SW edge of the Arctic airmass that eventually went on to produce the catastrophic Canadian ice storm. We started out with freezing rain but changed to rain before it got too bad.

    57-58 was quite unique.Nashville recorded the 6th lowest BP reading on record in Feb.Also into April had its 2nd strongest wind readings.There was the big blizzard in March in the east that dumped 2-3 feet along Conte.But it was so cold here that winter JAN/FEB it froze the waterways in MID TN.Plus we had the typical severe outbreak in Dec 57,with strong NINOS
  21. LakePaste25
    My opinion is that it’s such a strong looking event that you leave less room for things such as the PDO to influence the pattern, especially when it can potentially flip. It’s still early in its development. Previous winters the ENSO state was fairly weak so there were more opportunities for competing influences to destructively or constructively interfere.

    Let’s get that cane there into the Bahamas
  23. Chinook
    Today it will be 21-24 degrees celsius at 700mb over part of Colorado,. The highest temperature than Grand Junction, weather balloon sounding archive, has ever measured, is 22C

    Give us some Bahama Blues
  25. roardog
    Also the strong -PDO which we currently have that probably also ties into the MC influence. Globally there are big differences compared to 1997 at the moment and like you said earlier, it probably is NOT for the better if you’re a winter lover.
  26. LakePaste25
    I’m towards the “it’ll be a canonically coupled event” camp. And for the record I disagreed with takes during 24-25 and 25-26 that we’ll see predominate RNA pattern (we didn’t). So i’m not just saying it because I want it to be warm.

    97/98 Nino year was the only one I can find with ZERO lake effect events after Jan. 1st for Erie/Ontario. There were only 4 events total, all before the new year. https://www.weather.gov/buf/lesEventArchive?season=1997-1998&event=A
