3rd Annual Snow Thread for the Mountains


Met1985

Recommended Posts

Yeah 00z euro looks very favorable for snowfall Wednesday into Thursday.  Timing could be a bit better but the details still need to be hammered out this weekend.  A couple ensemble members have a pretty big snow.  GFS is too warm and east but at this time, I would much rather have the Euro on our side compared to the GFS.

Lol you must have been typing when I was. Yeah I agree leaning towards the Euro just because it has done better sniffing out the pattern better in the mid ranges.

Agreed Met and haha I think I was.  This one just looks like a classic WNC snow.  If we could get this to slow down a bit and come after the sun goes down we could really be in business.  The Euro has hinted at this solution for the last 3 runs and now we are within its prime time to shine.  4-6 days is when the Euro shines so I am feeling it with this one.

not really, it develops too late.

Weatherbell maps give AVL 5.8". Might not be all snow but that is decent precip and surface temps look favorable. Frankiln may be on the outside looking in but we all don't live in Franklin. Not trying to be rude at all man but we are still 4 days out and a lot can change. Just be happy to have something to track!

no offense taken, but I have been tracking these storms for many years, even before the internet. Unless we get an earlier phase and we can get some gulf moisture we won't see too much in accumulations, asheville included. And even the most phased solution right now has us on the edge, be mindful that the lesser extreme solutios like the gfs,ggem are possible.

Euro ensemble has 41/50 members with accumulation and 16 with 4"+.  I will take my chances with the 18z GFS now showing at least some precip in wnc.  Nonetheless just happy to have something to track and glad we can discuss without anyone getting mad or upset.  I respect your opinion.

thanks, I don't recall ever having a white thanksgiving before. That will be neat. I think some snow will be in the air.

Edited to add. This Nov has felt more like January with the temps and constant tracking.

Agreed Franklin, I can't remember so many mornings below freezing in November in a while.  Usually we have a few mornings below freezing but every morning last week was near or below freezing.  At least soil temps are favorable for accumulation.  It makes me wonder what January will hold for WNC, I believe Met1985 has hit 0 already at least once maybe even twice.  Hopefully we can get a few -AO's combined with two or three coastal's.  That would make for a nice winter!

I think we will be fine once the seasonal jet sags farther south and can "lock in".

Even down here in the flatlands, we have gone below freezing on 10 days.

I think the models will come around for the Wednesday/Thursday event, reminds me of a few systems we've had the last few years where all seems lost due to a late phase or no phase only to end up working out for us. Still plenty of time.

Thanks everyone for the comments on my video I made, should be getting some great footage of most of the ski resorts on the east coast this year!

You should do more projects around Asheville area :) Landscape of this city is amazing.

That is impressive for yall down there. Ward I have hit 7 and 5 degrees this season already. Not zero yet! Lol. Yeah we are still way early in really nailing down anything at this point. It will be cold though but snow I am not really sure of as the models have not been very consistent recently.

Euro ensemble is eye candy guys... 43/50 with accumulation for KAVL and most are above 3".  GFS finally got the memo on the 06z run and brings good moisture into WNC.  Surface temps stay below 35 throughout the whole event.  3 days out with the Euro looking so favorable, I think its about time to take it to the bank.  Haven't ever seen the Euro ensemble be that far off yet.  NWF will also be active going into Thursday per GFS.

I am starting to come around as well. At 72-96 hours out, we should be in the wheelhouse for Euro to score big on accuracy. A few other points of interest:

1. Very latest 09Z SREF starting to come around as well...prior runs had but one member showing snow. Now we have about half the members on board, with one showing 7" for AVL.

2. What is very troubling is the parallel GFS being so different! It shows nothing for WNC. I was under the impression it was supposed to be able to compete with the Euro. So it's not about model resolution - it's about data ingest! Euro still slurps up the most data before it begins running.

3. Let's not focus on QPF too much just yet. If it's a Gulf low origin, then moisture is a non-issue if the dynamics are there. Watch how the low develops along the stalled boundary...the very same boundary going through the mountains on Monday. The dynamics should unfold with a lot of background potential temperature gradient to work with.

I also think we see another 50 mile shift west again by the models before the usual oscillations thereafter. My experiential history of gulf lows is that they almost always end up further west than originally progged.

Good post HT!  Yeah was just about to post the SREF, it looks favorable for accumulation.  I am also disappointed with the parallel, though if this storm doesn't unfold like the Euro is depicting, we will all be singing the parallels praise lol.  Here are the plumes from the 09z SREF @KAVL.

Yeah if this keeps trending west this could be a huge snowstorm for the mountains at one of the worst possible times of the year.

 

What great trends overy the last 24 hours.

 

 

Yeah anyone traveling through the Gorge would be smart to come through Tuesday night because I could see them closing it.  It would only take one wreck to shut that stretch down.  I love the trends Franklin, this feels like the 09 storm all over again!
