Exactly, which is why I’ve been stressing about the energy either ejecting out in pieces or a lot weaker. Todays runs are drilling a much stronger wave coming out west and we’re just cooked if that’s the case. I got a little excited for about 6 hours between 00z cmc and 6z gfs showing weak wave getting squeezed under the block but models quickly adjusted. The GFS’s insane odd run is just it’s own way of trending towards a cutter like solution imo.

We need that to get beat down so a followup can come along and do its thing. 

Eta: but with that said, we DONT want a March 1993 storm  over the Plains resetting the entire hemispheric pattern either.

As much as people are denying, the SER base state is a real thing. I keep hearing that isn't a ridge in the SE at 120 hrs it's just a response to the digging sw out west......which is a ridge....in the Southeast. It isnt going anywhere, yet.

Lets look back a few runs on the GFS before more energy was dumping into the western trough in response the the amplifying EPO ridge because it cant escape west. What do you notice?

Weaker blocking,more energy lagging behind developing 50/50, ridging in PNA as opposed to SE, kicker on the heels of the NW energy feature. Also more connection between the 50/50 lag energy and the energy coming thru the WC

imo that's just a result in wave spacing and a ridge being built in front of the s/w. that's not a "real ridge", temps are still below average and so are 850s, i think it's just a response from wavespafong

I get that, but there is still an increased tendency in that region to build ridges faster and stronger in this Nina.

But the niña isn’t what it was earlier this season. That bitch is all but dead.


It’s a tough emotional rollercoaster when everything’s failed us all winter. I get it. Im there too. But we’ve also failed over and over in the midst of a MISERABLE longwave pattern. Outside of a few 2-3 day windows where we had a potential thread the needle opportunity arise, that pattern has persisted since January. PSU hammered down on that point all winter long. We failed because the setup was god awful and we were praying for things to work out in a setup with a near 0 success rate for our region.

For the first time in 5 months, we are heading into a strong MJO phase 8. We have blocking, a 50/50 low, etc. La Niña is also finally dying out. The atmosphere is going through a complete overhaul, so I REALLY think we need to be patient with models at this range.

There is little chance they are going to be able to nail down these details at range or be consistent in how they analyze them. Initialization is pretty crucial to any given models output, and they are initializing in a completely different pattern. This all matters. Which is why we need to step back and analyze the teleconnections and the evolution at 500mb, and allow the OPs to figure themselves out along the way. Even the fail solutions are WILDLY different from run to run. This gives me near zero confidence that their outcomes are correct either. Not saying we HECS, but I see zero consistency, which means we need to be patient.

this has always been the case, no? that ridge is doing nothing tho, it's like those light blue anomalies u see in front of a trough sometimes but it doesn't matter bc ur still torching at the surface

Nice, healthy -EPO and -NAO on 18z NAM at 84hr. I can see the lower latitudes fitting under this very well.

Maybe the earlier piece trends. It seems for that for an EC trough/snowstorm, they always want to make it GOA low. 
(^That -EPO is too organized and strong for a strong, sustained SE ridge.)

Euro looks exactly like this at 90 hours so not really sure how great this would end up being. The lead edge of trough shoots straight NNE instead of E and doesn’t do anything to the ridging out ahead of it, then main energy comes east and it’s lights out.
