December 2024 - Best look to an early December pattern in many a year!

From @SnowLover22 on the Mid Atlantic forum:

“PDO trending upwards the first half of December. @psuhoffman what is your target value out of curosity.

If I am understanding the PDO correctly, the general "trough pattern" over the North Western Pacific Ocean that has been ongoing and forecast on the models should act to continue to help cause the PDO Index to rise.”

93 was pretty epic as I recall. That's the year NYC closed the bridges for de-icing on several occasions. I think a pedestrian died from falling ice on a bridge. Snow on the ground for weeks IIRC.

Yeah, 92-93 and 93-94 were both great, 94-95 sucked big time but a great rebound for 95-96 was the best.

How big a deal, we lose the +PNA?

Yeah man, we recorded 2.29” rainfall at Mtn Ops Center but all of it was a cold rain.

The Mansfield Stake went from 38” fluffy to 33” water injected glacial pack.  Even in the base area, the loss was probably even less as it was colder wedged in there.

Down at my place we are at 6” from 12”. I thought it was going to be smoked.

Conditions are a bit rougher than they were, but even still, some low angle natural snow terrain was back open, which means it’s not terrible, ha ha.

The big thing here was a 500 vertical foot washout on Gondolier.  These seem to happen in a different place each Dec now when we get the big water amounts.  This was the largest yet and requires excavators to fix.  These channels go deep into the ground.  The power of water is crazy.

Will they be able to fill that with snow for the winter?  I’ve seen groomers make snowmobile trails out of terrain you can barely walk on but ski trails might be different.

Yeah, the good thing about Stowe is that when stuff like this happens, there are resources to throw at it quickly.  There were winch cats out there working earlier and the local heavy equipment contractor is fast acting… excavators needed.

Roughed in, the trail will just need a good snowmaking run.  Frozen QPF will fix it.

PDO doesn't really drive the pattern...it feeds back, especially when extreme...but its more a reflection of the predominate state of the atmosphere.

Wow, worked in the race dept running the nastar course for years before they nixed it.  Needless to say I know that trail well.  Im interested in the path water takes and that picture is funny to me because that a part of the trail that bumps up when not groomed.  Not sure of the correlation there but interesting/

I guess I wouldn't expect snow if I lived there?  I mean, my family is from SW Georgia.  I don't think I would be all that upset if I was visiting and there wasn't snow.

EPS was a disaster with the pig in Alaska starting to show at the tail end.. Amazing flip-flopping on 00z and 12z .. Wake up to same old December from 00z , then all weenies rejoice at 12z for several days now.. Although all guidance does agree on a Nation wide torch after Christmas Day and some cold leading up to Christmas. Non-Scientific opinion is the general 00z theme will end up winning out and we wait til well after New Years...
