January Mid/Long Range Disco 3: The great recovery or shut the blinds?

Recommended Posts

The biggest reason I remain skeptical is in recent years when we did get a poleward epo ridge, even an eastward one banked up into western Canada, instead of dumping cold into the central US it digs a trough Into the southwest and pumps the SE ridge. This has happened several times. 
 

Frankly the reason I’m tired of the “it’s the pac” excuse it that’s lazy. We’ve had different pac longwave patterns that all end the same for us. Flat central pac ridge…raging pos AO western trough we torch. Pacific trough, floods pac puke, we torch. Epo ridge, digs trough deep down the west we torch. 
 

No matter what the pac longwave pattern we can’t get a pna ridge for long. And I suspect there is more effect than cause there.  It seems to me there is resistance to a trough progressing east so even when we do get a pac that should work, and yea that’s been a minority, it still doesn’t it just digs a -pna even more instead, even when the pac ridge is far enough east it should press the trough east more.  The Atlantic is just as big a problem Imo.  There has to be a reason other than just the pac why troughs want to dig to Mexico out west no matter where the pac ridge is centered.

Gfs horrible run so far

What tropical forcing there is should be favorable to the trough shifting more east.  The pac ridge extends all the way into western Canada. But the trough just cuts off into the west instead of pressing east. This has happened each time we’ve had a -epo recently.

I think all the ridging in the 50 50 region is helping force the trough to the sw

it’s a long range OP run

My point about troughs digging into the SW regardless of how far east we get the pac ridge…there have been times it was well into Canada and the trough just cut off under it,  was not made because of the Gfs. It’s just ironic the Gfs does exactly what I said.

I know what you mean. not really sure why it happens, either. probably a mixture of some bad luck and Nina crap, who knows

More to come apparently at 384

That’s my point. There is resistance somewhere else also. Im not saying we haven’t had a hostile pac much of the time. But the times we didn’t the SE ridge has still been winning.

look at this. Aleutian trough. Trough east of Hawaii. Fill latitude epo ridge centered into Canada, east of AK even!  The pac isn’t causing whatever went wrong on the Gfs. Just from the pac longwave pattern you would think the whole US is being overrun by cold not a trough digging to San Diego and a torch east of the Rockies. Our issues run way deeper than just the past.  The pac is amazing here and we still torch!

So then...what's causing the SE ridge being as strong as modeled? Warm ocean or?

Nina’s cause a -pna because a canonical Nina causes a central pac ridge which naturally favors a pna trough. That doesn’t explain why when we get rare favorable pac forcing to press that ridge east the trough still doesn’t progress but just cuts off under it. That has to be resistance downstream.  Troughs either lift or cut off out west even when the longwave pattern upstream suggests otherwise. Something on the Atlantic side is a problem also imo.

The se ridge is just a response to when a trough dives into Los Angeles. His question is why is that happening no matter how the pac looks. I'd say the last 5 winters...the blue is on the west coast 80% of the time lol

Troughs are amplifying way sooner than I ever remember...I've literally seen 15 straight cutters on the gfs since mid dec

This is not great for me mental health.

Ain't good for anybody mental health, lol I am finding that too much exposure makes ya see the lack of snow as a bigger catastrophe in life than it actually is. Disappointing? Absolutely. But in life context? Not as big as it appears...but when you're on here all the time when we're struggling for snow, you'd think the world is literally ending--but it's not quite reality.

So are you genuinely perplexed or are you trying not to say what it is?

Also we get a western trough with a negative ao and nao....like in December? Seems like a physical impossibility but here we are

Its most likely that the 50/50 low has been nonexistent and there has been somewhat of a ridge there...this probably is the ultimate problem

No its actually ending. We have a mental illness that nobody wants to admit

There could be something too that though.  Think about the flow. As the flow goes up just off the west coast and into western Canada the wave in the west SHOULD be forced east. If there is nothing causing a kink in the flow. But if there is resistance to the flow east (think of putting a stick in the water and watching the flow back up around it) that would cause what we’re seeing. Something on the Atlantic side is resisting troughs professing east.

We have a 90 day window for snow every year and it snows 1 day of that window. This hobby is as unhealthy a hobby as you can find. The only benefit is its educational but 99% of the people who get snow make no effort tracking it. They just wake up and say....oh look its snowing

Absolutely. Much bigger problems in the world. This just used to be one of those hobbies that was innocent and pure enjoyment. Those are based off of the expectations though. Which clearly do not add up with the reality. 
 

The hope is still there, I likely will not stop until St Patricks day or when the true heavy hitters in here raise the white flag.
