  1. 40/70 Benchmark
    Does anyone have a site where I can generate 12/1 through 3/31 temp/precip anomaly maps? All of the sites I have checked do NOV-APR, DJF, JFM, etc....it's so annoying. I can't find a site that will allow me to manually enter an arbitrary daily period like PSU had....they all bin them into predetermined periods. I can use the ERA 5 dataset on PSU: https://psl.noaa.gov/data/atmoswrit/map/index.html But it plots temps using degrees kelvin. Does anyone have a site that can generate DJFM temps maps using degrees F?

    That is what we want to see to avoid the dreaded cool-ENSO-like se ridge during the coming season IMHO.

    I have to be honest...I'm taking it with a grain of salt at this stage, too....to be fair to Adam. If it still looks like that in October, then it may be time to take it more seriously.

    Yea, WPO was still + on the season technically per calculation, but no doubt there was more volatility this season. I think we are likely to see that continue.

    Very clever ploy in editing in the shout out to me, so as not to exhaust 1/5th of your daily allotment of posts!! 'Cmon, dude....you know I'm not a JB.

    Yea, I mentioned that in my March recap...there is often a bonafide Pacific trough regime about 10 days following PV splits. Showed up in two of my primary analogs: This split of the PV was then followed by a strong Pacific trough regime that resulted in record warmth about 7-10 days later, which was in fact very comparable to the sequence observed in the wake of the February 2018 analog-warming. This is same phenomenon also occurred to a somewhat lesser extent in 2001, as very warm temperatures with highs in the 50s also occurred on February 20th, 2001, which is 10 days subsequent to the February 11th, 2001 PV split.

    Okay, this is what I focus on...the reversal, which is why 2023 didn't register with me. I know February 2023 had a reversal.....but wasn't under the impression that the 23-24 season did.

    1982-1983 is the only super El Nino that had kind of a favorable WPO, which is likely why the NE managed near normal snowfall. While I could see something like that, I do have a hard time envisioning a cold season.

    Snowman must have missed that part of the seasonal forecast in his tweet regurgitation.

    Chuck, I think I do recall some blocking during 2023-2024 now.....I remember Chris going on about how the se ridge was adjoining the NAO blocks that season, which is what killed us....likely a byproduct of the cool ENSO residue that persisted that season (RONI lagging ONI).

    Just harkens back to my point about the monthly tabular readings not providing an accurate portrayal all of the time.....you need to view the dailies because there were significant -WPO intervals this season, which is why it was so cold with more snow.
  12. 40/70 Benchmark
    I understand that, but I simply didn't recall them...probably because they were useless.
  13. 40/70 Benchmark
    I felt like it did, too, so the monthly numbers are incorrect?
  14. 40/70 Benchmark
    It doesn't make sense to me, either...but those are the numbers.
