The elusive post New Years 2013 storm system (Accumulating snow possible)

The Polar Vortex looks like its gonna stick around for a minute causing several pieces of energy to cause multiple light snow events. Maybe even a more moderate to heavy event just after the new year!

MRX starting to mention the snow word now too with this weekends gulf system

Its the 84 hr nam which is to be taken lightly but it shows a classic southern slider TN snow storm. If it verified it would give most of the state accumulating snow!

Ive extrapolated and penciled in where the shortwave energy would travel..the snow swath would be and the surface low track path

I must be teh only one excited about this pattern? The Euro has been suggesting a phasing storm near to just after the new year several different runs in a row now. It actually showed a triple phaser a few runs ago!! (if somebody wants to see that I can dig it up)

Here is this mornings Euro showing a classic double phaser which would clobber alot of the state if this 500mb animated gif was to verify

Wow Toot! I'd love to see that verify, I'm just afraid with all the chaos in the models that I'd be setting myself up to get excited and then it not verify. However, if it did phase like that, then yeah we'd be happy. I guess we have to look at trends, which are still supportive of wintry precip during this timeframe, and not look at every single model run that comes along. However, it sure is easy to get caught up in that model madness, esp when they show what they did a few days ago. I fall into that category of model hugging, but have just about conditioned myself not to. We'll see what happens here, if this doesn't work out, then maybe the next one will. After all, there will only be so many non events before we hit it big again lol

I dont really have much doubt that we see a light accumulating snow event or two over the next 10 days from the northern stream! NW Flow/Arctic front snow...I think thats almost a given for NE TN at least.

Im more worried that our big daddy will be too suppressed due to the strong lobe of the PV crushing everything southward or shearing anything that tries to come north

Anyways the 6z GFS ensembles are certainly interesting looking at hr 150

I wish I could keep my eyes off guidance models for just one day but the Arctic intrusion mixed in with such an active pattern has the models throwing up continuous snow threats from all directions. Snow threats are everywhere. The NAM continues to suggest that there will be another threat around Monday/Tuesday..its actually forming another LPS along the arctic boundary. If its correct it will be a winter wonderland around here mid week and yes I know its hr 84 of the NAM but its so sexy I had to weenie out and talk about it..lol

Classic southern slider setup there!

I am with you!

I'am excited about it as well! Looking at the 12z gfs it is starting to catch on again to the New Years storm. It has it further south and east but I think that is a good thing the way the models have been. I see it trending further nw with time! BRING IT!!!!!!!

For New Years in the Chattanooga area a dud, other than some snfl. Daytime highs for my area are around 39 - 40 degrees. Clipper systems coming down next week. Maybe good for your area. Have a great weekend everyone.

Cautiously optimistic here. Have gotton fisted too much to get too excited.

LOL..how in the world do you know this Windstorm? Are you just talking about New Years day or what? Guidance models cant even agree on anything right now! There is a large scale pattern change taking place as we speak and the storm track will be much further south and east!

There is the matter of another Gulf low that the Euro has suppressed the day after new years with an Arctic airmass already in place in Chatanooga!! From experience I know that these almost always trend north and west a bit. I will tell you what... I would rather be in Chatanooga for that one as I would Bristol

I tried to fix your image URL but it seems pretty dead/broken. So I will post the latest GFS snowfall accumulations and setup late next week..but its likely to change! I think the GFS is too northern stream dominant with the monster clipper. The euro has nothing like that! Im not sure any model is handling the situation correctly but I will take the GFS and run with it..lol




Manitoba Mauler anyone?

Can't say I've ever been fisted.

Thanks toot! I don't know what's up with the URL? But your right it will change.

Man..im biting my nails over each model run. Ive never seen guidance struggle so much with a pattern change. Hopefully that means something big or historic is in the cards! The euro showed a monster phase on several different runs..im hoping it comes back to that 

I know it is hard not too! I won't sleep for days for looking at all the data and model runs. The NWS had info on the snowstorm on newyears eve and day of 1963-64 that was interesting of how much snow fell with that storm. Nashville had 10in and south of there was up to 15in. But the storm track was all the out in the Atlantic past Florida. Impressive!

I read that..looks like most of that snow was caused by a lagging but powerful upper level low. Very sharp looking trough too..it was an interesting read/system

 Fisted defined as: "2. Getting the short end of the stick, Getting a raw deal. The extreme of getting fucked, screwed or getting the shaft, involves more discomfort on the part of the fistee." More specifically, in my case, receiving only furries or a dusting of snow instead of 2 or 3 inches forecasted. Not in the way u perverts were thinking.

Haha..thanks for clearing that up for us

LMAO, still sounds painful. FWIW I was just messing with ya.

Yeah, wanted to clear that up right quick! LOL!

As expected the latest run of the european model shifts the suppressed gulf low a little north! I expect more adjustments north will continue the next couple of runs putting northern AL and GA into the game! Pattern will support classic "Southern Slider" snow storm.

Here is the latest from the european. I expect this graphic to start showing snow further south into GA AL and possibly MS the next few runs.
