Going back to 2019, the Atlantic-Pacific have changed the same day (D-0) (D+0) every-almost/every time. (LSD experiments started in the 1960s)

St. Louis-east. very broad-strong general signal. we are wet St. Louis east this Dec <- +NAO-correlation/both considered

Still looks pretty ontrack.. you might be surprised. Dec 17-20 and all.. -NAO in the midst of a wet pattern, The only wet -NAO/December was 1996. 11/12 were drier than average, since 1948.

It's just too many damn .exe's! Firewall isn't in agreement with the root problem..

it's probably some kind of blood, pain, nervous system disorder. lol

I have these deep black bugs, like military aircraft(heavy-weight) projecting .exe's into my computer (blue ring around mouse)and I really don't have a choice, to use my computer, but to channel them to something like weather models (info gathering, at least). My computer screen is like a puddle. clear-water-puddle from 10,000s tiny bugs. Maybe someone can help? (non-visible) I don't want to be doing this all day. It also feels wrong. Seems to happen after I make weather predictions, etc, anything that could be economical. Not a big deal though after 12-18 hours of clearing .exe's.. imagine little bugs projecting red lasers from their top forehead.. lol Don't know what to do about the problem in masse, it's starting to create a wall that's independent of the computer, which is what I don't like

When -NAO wanes.. that's when we'll get our snow

And what do you know, this might be a real snow threat

That's not a -NAO on the 00z GFS MR

40% average snowfall every year for 20 years.

-PNA has to shake, sometimes the EC storm threat will take over and dominate N. Hemisphere pattern (usually it trends back to -PNA in the last few days).

The information in that thread may have gone Penn State Meteorology Department

little relevant science left

climate is running like an old record.. anti-global warming I guess, technology like this was 1920-40s.

This is what happened last time we had a Kelvin Wave in La Nina in the Winter (Dec 20-Jan 5)

This is what happened last time we had a Kelvin Wave

18z GFS had a 588dm ridge on the West coast. 12z GEFS had nothing at all. With this subsurface-ENSO configuration, we aren't going to see a west-based -PNA in Jan and Feb, like we are seeing now in Dec. Jan 500mb could be similar to last year.

Yeah it seems like we are building up a lot of potential energy.. that's all maybe

>+7f hitting 180W now.. they sometimes look like this before Strong Nino's but it's December.. 12/5. atmosphere seems to consider Jan-Mar in the subsurface historically. I think I found it was like 3-1-3 before then.

^Same as last year though. (Subsurface)

^Same as last year though.

Analogs for Dec 21-29 +PNA (snow) are: 2005, 2002, 2001, 1995, 1975, 1973, 1963*, 1952, 1950.

Analogs I am coming up with for Dec 20-24 are: 2005, 2002, 2001, 1995, 1975, 1973, 1963*, 1952, 1950. (Dec 20-24 is rigid, make it Dec 16-29 those years). 1) Dec 21-29+PNA, 2) Dec 10-20-NAO

Poor DT. When the PNA is negative, and has been in that phase for >20 days in December, our odds for snowfall are significantly low. Especially since it's technically not Winter yet. Dec 20-24 is our window.

Does don or anyone know what NYC snowfall is like, coming out of a 4SD -NAO? Better yet, what happens, when that rise is associated with a positive PNA/or GOA low as I think we are going to reverse thisv. could make a window a few days before Christmas
