Pattern January Joke

The progged nao blocking at least gives us a chance at something wintry while waiting out the persistent Aleutian ridge, even if the windows are small and the chances are low.

It beats a persistent SE ridge.
We score way more with tight windows of opportunity, Than we seem to with the wide open Holy Grail looks. Speaking for my own area. Last year would be case in point. Deeper south you go, more it takes the Holy Grail Pattern looks to cook something up. Either way it always takes impeccable timing no matter what.
 
That just looks like the average pattern for most La Nina Januarys the last 30 years
Brother I am not worried about what the last 30 years have done, I am trying to find hope with ending a terrible pattern in early January. I didn't post it saying that it's a Winter storm signal.

Well you should be concerned about what those Januarys produced because that’s where we’re very likely headed.
 
Look how much colder the SE got over one week of EPS runs for late month all due to a strengthening -NAO despite the Aleutian ridge not budging as per my Dec thread post.

I can’t say I didn’t see that coming

I'm having a hard time being sold on the giant ridge that extends from the Southern Plains to Europe on the weeklies, just using Jan 4 here as an example.

In reality, I suspect we could end up w/ a much more wavy & slow pattern with shortening wavelengths as the blocking high retrogrades just south of Greenland while the upstream Aleutian ridge refuses to budge. May have to be on the lookout for cut-off upper lows.

Maybe you're right, maybe you aren't. Either way, I don't really care. I am just here enjoying the weather & trying to figure out things 1-2 weeks at a time. I'm not about to just accept an entire month of Winter is over based off what it did in the past.

The good news is the median snowfall at Raleigh in January from those winters is measurable (~0.5”).

December wasn't too far off from the median either, which hovered around a trace to a dusting.

Well keep in mind that over the last 30 years worth of La Nina winters, the majority of the time it did snow in places like central NC. Even a standard Nina January would still be ok.
 
January 2000 was a strong La Niña. Now I believe that changed later in the month? Then after the halfway mark we had three separate winter storms including the monster January 25, 2000 storm. I know that’s only one January example but that was fascinating to me and always will be. Mainly because at 7:00 am on one of those early first half of January mornings we had a strong thunderstorm at 70 degrees. We had a few 70 degree days before the flip. I guess what I don’t know is if the flip was expected or unexpected. The 25th storm was definitely a surprise here in Central NC.

Besides the Aleutian ridge that seems to be stuck in cement, a positive PNA would open up the Gulf Stream for business and give us a better shot of having moisture available to work with when cold air is available. Even if we didn't get any wintry precipitation, any precipitation at all would be welcome over much of the South which has been under a dry spell that has produced drought in many areas.
 
Believe the PV is splitting again. That's what is shaking everything up. Hopefully for the better.
PV is forecasted to stay in a disruptive state for some time, at least through January into Feb, is vibe I'm hearing. This is what gave us the 20 straight days BN to kick off met winter
There is no doubt the disturbed PV will continue and that is at least something we can look forward to. The last time there was such an early SSW the PV didn't recover according to past data. This should at least keep the colder outbreaks coming. Just need the right disturbance to meet up.

That was the greatest 10 day stretch of winter wx in central NC, at least in my lifetime. You are correct, it was an island of winter in a Sea of warmth. Spent 7 of those days without power unfortunately. That 1st event of .2 minuscule freezing rain, was still on the limbs Monday night, when all that snow blew in. Trees caught every single flake. Got followed up Thursday by another 5 inch pure snow event. Had some single digit lows a few nights, thanks to radiational cooling and all the snow pack lying around

Yes! That’s exactly right. I remember watching one of the conference championship games the Sunday night before the big 25th storm. They were calling for clear skies the following Monday night. Then they changed it to flurries, then to 1-3 inches of snow and then almost two feet fell. That’s a good memory on the smaller storms before that left a little bit of ice which I think was the 23rd? Then the 5” of snow a week or so before that? I still can’t get over how warm it was before all of that the first half of that month and back then I’m sure most thought spring was making an early arrival.

Grasping post: Normally I'm not at all enthused with no pacific help and all -NAO/wedge related patterns. But perhaps since the cold/PV is on our side of the globe, and Canada's very cold, maybe what's blocked and wedged down will be cold enough to do work this time. Maybe?
Yeh if we are going to score at all over the coming weeks, it's going to be a classic CAD set up.

That look on the end of the AI is probably gonna reflect with a lot of big dogs on the means in the upcoming days, it’s likely the ens trying to sniff a cutoff. Good example between the ens/OP, which shows a cutoff with cold rain, but it’s not far off
