This isn't that favorable of a 500mb +WPO/+EPO.. NAO isn't that strong one way or another, CPC actually has the NAO positive for the Winter so far. I agree that the base-state is -PNA/-PDO right now. It may be connected to the +AMO cycle and general Hadley Cell expansion. I think these decadal cycles wane eventually.. I was half expecting us to have a Winter like 57-58 this year.. the PDO went from ridiculous negative to nonmatter that Winter.

Dude.. the -NAO is so weak now. I was right, when storms start cutting on models, and surface goes warmer, the models are usually adjusting the upper latitudes too. That's what happened. The blocks you and brooklynwx keep showing are ridiculous. We are no where near that -NAO strength. There is no disconnect also. It's fitting what we've seen over the last 2-5 years. But like I said before, when we are hitting -PNA at the end of this cycle, the SE ridge flexes/EC gets warm.. I'd watch for that later in the month and possibly next Winter.

El Nino 2023-2024
Stormchaserchuck1 replied to George001's topic in Weather Forecasting and Discussion
There is now a -3c pocket in the central-subsurface on TAO/Triton maps. NOAA said 55% chance La Nina develops by the Summer a little while ago, based on the subsurface. It may be a little higher now. -
Winter 2023-2024
Stormchaserchuck1 replied to Stormchaserchuck1's topic in Weather Forecasting and Discussion
Since it's slow, I'll say again that NG is 1.86, the over/under on March temps in the NE/GL's with this is +5-7F. My guess is because models want to develop a -NAO/AO from the February Stratosphere warming, there may be -PNA/+EPO in March. -
El Nino 2023-2024
Stormchaserchuck1 replied to George001's topic in Weather Forecasting and Discussion
I wouldn't bet on fluke heavy snow in the SE. There is heavy trend against it. Even when the upper latitude pattern is favorable for them the last two Winters, it's not even really close. -

Nobody's into it, but we get some wrap around flurries Tuesday on the 0z NAM. Low pressure is really strong, 980s mb right when it exits the coast off of Ocean City. -

Up where I live in Harford County, I might get 45 minutes of heavy snow.. may add up to a dusting or 1/2". For the 5-10% chance, A small shift south could be a big deal though. -

18z Hrr fwiw was colder than the NAM with the 0 line at 48hrs https://ibb.co/s1FZmsS -

Really close for northern MD on the 18z NAM. Close, but a miss. 850mb temps are near 0 at hr63 heavy precip close Actual SL low is off of Ocean City MD.. -

NAM is definitely more amped this run https://ibb.co/vhgMX70 -
12z GEFS: PNA is negative for "PSU storm".. I don't care what the NAO is doing, the Pacific has overwhelmed the Atlantic constantly since 18-19. I mean, with the way it's trending, we may end up in the 50s. I still think PD is our best shot at snow, because it has the most favorable upper latitude pattern. When subsurface ENSO changes happen, the N. Pacific pattern does adjust, sometimes even despite what is going on at the surface. It's a fairly successful forecasting method. The -NAO/-PNA/+EPO, +NAO/+PNA/-EPO correlation is holding. Models were showing a break, but it backed off of the short term -NAO, associated with +PNA, and went stronger on long range -NAO associated with -PNA.

Really getting warm out today. -
Warm out, 60 degrees, and I love it. I've been seeing all this Spring grazing birds, and they are moving like it's March-April..

We lose the -EPO and the Japan ridge is moving east. In verification, Surface temps would be a problem I think.

Yeah.. did you guys see the NOAA issued a La Nina watch https://www.climate.gov/news-features/blogs/enso/february-2024-enso-outlook-all-along-la-nina-watch-tower And it could be +QBO next year too.. and the last time we had +NAO we hit 80 in January!

It's not even a block. And the tendency is for things to be warmer.

Yeah.. that ridge near Japan is approaching the same extent. It doesn't even close off a block. In the last year, we've seen 3 stronger -NAO events (March '23, early Dec '24, Jan '24). GEFS is a weaker signal right now though, and 6z is more recent.

This isn't that bad from this range. What I don't like is the loss of 50/50 low on ensembles.
