  1. True, and also true about the south based blocks linking up with the SE ridge - that’s a pretty new phenomenon. I personally like numerical index values only because they’re easier to analyze in Excel or run a machine learning model on (one of my ongoing side projects btw). Not easy to do that with spatial 500mb maps, but it’s important to use those maps to validate any conclusion drawn from analysis using numerical indices. I’m also realizing that the NAO shouldn’t even be looked at in isolation, but in combination with the AO and other indices. The deviation of the AO from the NAO in and of itself should be a clue that something amiss is going on.
  2. Good point about looking at 500mb instead of raw index values (always a great reminder). Those 4-5 bouts of -NAO you mention, how many happened specifically in January or February? Pretty sure it’s slim pickings other than Jan 2021. We did get a brief episode this January that resulted in 10 days of winter, but it got washed out by the rest of the month that brought about record warmth in the MA.
  3. I also consider 2022-23 a +NAO winter overall: 2022 12 -0.1456 2023 1 1.2503 2023 2 0.9227 2023 3 -1.1088 Yes, the average is only +0.23 which may have some believe it a neutral NAO winter. But the -NAO episodes, while strong, happened on the shoulder months when, in terms of snowfall, may have helped a lot more had they occurred during mid-winter months Jan or Feb or both. In other words, if we’re looking at yet another +NAO/-ENSO winter, give me just one -NAO month and don’t wait until mid March to do it.
  4. The TL,DR is that there’s some uncertainty in how strong the la nina is gonna get. Models have backed away from its strength lately. But the PDO is still very negative and will remain so through winter, so enso may not even matter much for us here
  5. Actually up to 2.17” on the month. Slowly getting better, but June put me in a deep hole that’s going to take a lot to climb out of.
  6. Sneaky heat. Quietly creeped up to 92 today. Humid
  7. Radar looks sparse today. We can’t nickel and dime our way out of this drought.
  8. I know this is just skin temps, but that cool area breaking up the marine heat wave is interesting - west of Hawaii starting 20N at on NEward. Was there a recent storm along that way?
  9. Back edge approaching, lets see how long the precip holds
  10. Much lighter precip than radar would have you believe. Probably lots of dry air layered up aloft
  11. I wasn’t tracking yesterday’s storms because I was busy preparing for a job interview. So I just checked and saw that I got 0.52” imby. Not bad.
  12. Thanks for sharing. I had been wondering what the 30 day rolling average was up to yesterday And yeah, that is pretty hot!
  13. Yeah lol i mean, it had gotten much cloudier earlier today and yesterday, whereas before it was clear skies end to end. Felt like super mario 3 where the sun is trying to kill you
  14. 97 so far imby for the high. Cloud cover for the most part, don’t think I’ll make it to 100 but DCA might
  15. Was fun for a few minutes. Not severe though. I’ll take it.
  16. Trying to reel this one in… cell right on my doorstep. Very gusty winds and rain is starting
  17. Only 11:30 and I’m already at 97! Wow Make that 98
