It's just weird looking at all this... being in a Nina... and having such an un-Nina pattern.

High AAM state with additional MT possibilities should keep the GWO in a high AAM state. No SE ridge for the forseeable future lol.

It looked like the AAM was falling again a couple of days ago, but I haven't looked lately.

Then how can there be a "gradient pattern", especially in the East? When the Arctic air verifies, a lack of a SE ridge screams suppression, far from a gradient.

Because the flow will turn more zonal with higher heights and warmer temps to the south, and cooler temps to the north. I think there will be some se ridging...ensembles may not pick out those features, so far out.

Seems like we have been hearing the term "gradient" and 1994 alot this season, yet it hasn't snowed since the leaves fell.

This is the first time the models really have shown a true 1994 pattern, but there are alot of differences. One, the PV is still located well north of where it was in 1994 on today's Euro, there is little STJ this year compared to 1994, so there is nothing in the southern stream to run into any arctic highs that might be cutting across S Canada in this setup, and the La Nina also can cause more of a SE ridge effect.

Yeah that's why this pattern still sucks.

One thing we haven't really seen.

I think by D15 we'll probably be popping some SE ridging but it's not a classic "gradient" pattern as I use the word with a -PNA/SE Ridge and a PV to the north.

I don't want a srn stream, because that could easily be a warmer solution. Systems coming in from the Plains and tapping the gulf is fine.

I'd rather an active southern stream with the PV to the north than the potential for a relatively quiet and boring northern stream.

See I don't think it will be. Even the euro ensembles had a nice trough in the midwest at the end. That would probably be a decent system. Maybe it will, but I don't think every system will be moisture starved.

In this relatively flat pattern it will be hard to get anything that cuts west, this meridional flow is exactly what we want or weak disturbances, as you said though as soon as you start running something too strong its going to cut into the Oh Valley.

Tough call....without a s stream, the risk is cold\dry, which is the absolute worst....but out best systems are born of the n stream. Miller A's suck.

Probably doesn't matter because whatever can go wrong, has and will go wrong this season.

Yeah by the end. I just don't see a whole lot of interest in the D7-D10 or even a bit beyond. I guess I'm just a bit frustrated that we finally got the pattern to change and we're not going to have a whole lot to show for it.

This is true, but again.,.where does it set up? If it sets up close by, and any system tries to get a little energetic...it's congrats Vim Toot.

I might be wrong, but I think we could get some SWFE here, and I don't think it would be all that dry. Some may be, but any little s/w that wants to dig, will have the gulf to their own, with high pressure just off the se coast.

Eh, you never know. Something around the 18th and 21 looked interesting. Didn't look too dry.

A southern stream like an El Niño? Well, at times during this first half of winter we did have one, but for the most part it is much less defined. But going forward on the ECMWF suite, there are two stj waves of interest. Not what I would call a lack of a southern stream.

Yeah I think you're right... it's just going to take a while to get there and I'm not sure how long we'll have this pattern to work with.
