It's a good year to look back on and see what can go wrong with a SSW/PV split and how that doesn't equal a cold US.

December had the strong tpv and a raging +nao that offer the attempt at pac ridging as the ridges bridged across the US. Jan saw the warming over Siberia into AK at 10mb but the tpv parked in AK and muted the western ridge that was warm. When feb came around we got a little Canadian ridging but by that point the tp was leaving for Siberia and we had a limited cold source that was still warm. (We got a little rain to snow event).

It's a decent analog for this year but I'm not sure the high latitudes and strat will behave exactly the same but obviously the potential that we lock into a warmer boring pattern is there

01-02 , 11-12 and 21-22 following the 11-12 evolution so far. I see a pattern developing here. If this winter is going to end up one of the warmest on record like those 2 I sure hope it follows 01-02 in the snowfall department. Never want to see an 11-12 ever again.

In NC, we had this crap storm, at least. It wasn’t a street sticker IMBY, though.

I’d take a inch of snow right now. Haven’t even seen the grass really turn white since Dec 2018. Mega frosts have gave me more ground whitening then any snow here the last 3 closing on 4 years, yes I haven’t had a storm with over a inch of snow in 3-4 years, when I average 3-4 inches of snow a winter

Graphs like these make the weenie part of me sad. This is the seasonal snowfall total and number of accumulating (> Trace) snowfalls at Fayetteville, NC since the winter of 1891-92 I've reconstructed using data from NCEI, SERCC, NWS RAH, & my own website. It's interesting to see that while the seasonal snowfall is decreasing (at a rate of about a dusting per decade), the number of accumulating events show no trend. That may be due to better detection later in the record, but I think I can conclude that we are certainly losing the "big" snows around here. Fayetteville's snowfall climo used to be ~5", which is pretty comparable to what Raleigh's is today. You see a similar overall theme of decreasing snowfall (mainly from the loss of big storms) at most places in the east-central piedmont and coastal plain of NC. At first glance, there doesn't look to be any trend or weakly positive ones in the far western and northern piedmont of NC (Triad region and areas W + N).

We're due?

The good news is in La Nina winters, the differences between haves and have nots is smaller (usually), nature usually spreads the wealth much more evenly east of the mountains. Plus, we’re more likely to get high latitude pacific blocking/-EPO/-WPO in a Nina to drive air from Siberia into N America. I feel like we honestly need that to get a good storm nowadays, -NAO on its own doesn’t deliver cold enough air consistently as last year showed. I had so much cold rain :(

I’ll be back in NC for the holidays. Gonna root for either warm enough weather to go golfing or a snowstorm ?

Maybe I'm just being a super weenie but I don't feel terrible about this winter WRT to snowfall potential. Now actually getting a lot of sustained cold....

Yep I think we’re above normal temp wise this winter. Some snows tho. Honestly most just want snow and that’s it so I personally like a AN winter with snow

Yeah it's hard to find a way to see BN this winter as a whole with Feb nina climo on the table unless we find a way to block like crazy through the first half of winter. Just playing with some analogs the other day I got an avg of 5 at rdu but a range of T-12 so a lot is on the table imo.

I'm encouraged by some parts of the pattern right now and if we can get some similarity in winter we have potential to unload a blockbuster or 2

Personally only time want snow is around Christmas … after that keep it and the cold too. Glad we have a great chance of a warm winter this season ….

Kinda the same way. However, I don't like above 32degree snowfalls. That one in 2018 delivered 8 inches here with temps 33/34, nearly a foot just west of Carrboro and Chapel Hill with 32/33 degrees. If that snow takes place with temps 32 or below, easily a foot plus here with excessive amounts just NW.

As bad as 2011-12 was, at least it produced an accumulating snow event east of the mtns, with an inch or two in the Piedmont. We’ve gone entire winters (esp in parts of the 70s and the 90s) where we had basically no accumulating snow at all east of the mtns. These are a few examples of winters I’ve analyzed, notice even in the south-central mtns, they had almost nothing in a few of these cases.

Good to see @metwannabe was about to get his reports in for all of these
