Dec 12-14 Apps Runner/Lakes Cutter Snow

[Adam]

I am just not seeing the potential for a big snow in middle tennessee at all. It looks less impressive then the last system.

I have adjusted the title of the thread to include the Dec 7-10 blockbuster that everyone is talking about.

The Global models all have been hinting at this potential in the day 8-10 timeframe with a major miller a type snowstorm being depicted. The teleconnections are supportive of  the same and the pattern seems primed for a major event.

The GFS has been suppressing this storm south of us but has since trended north and the latest run had nothing much at all. But most of the others are still showing this potential, and I expect the GFS to come back to it.

My personal opinion is areas along and north of I-40 look to be prime hunting grounds for this potential, but it's still early enough for anything to happen.


Here is the canadian as its good as any this far out.

Isn't the 540 contour still north of the state when the low decides to ride the Apps north?  It might not be, but I can't tell.

It looks to be right on the NC/TN line at hr 240 Eric, I would guess if that scenario verified it would clear the state in the next graphic, but this is still a ways out. Who knows?

I see the 540 line north of the state, I love how they make these maps almost too cluttered to seperate one thing from another.

I see the 540 line north of the state and it cuts through the middle of Louisville...

Yeah...that graphic is a bit more clear minus the progged precip shield.  Until the 540 contour clears the state, nobody's going to see much of anything frozen.  Of course, it is still more than a week out, too.

The 534 is right thru the middle of the state with the 540 south of that. These lines are blue, am I missing something??

I see it now, you are correct...it is right with the 552 geopotential height so it is hard to see, you have to trace the 540 line from up in New England down into Texas.

Thanks, I thought I had went crazy for a minute.

Yep....dang thing is kinda hard to make out.

Sure is, but meteocentre is one of the only free sites that go out to 240 on the kanuck to my knowledge.

Well the models are up and down with this one too, right now I am just hoping to get some snow showers/flurries on Wednesday. Pretty much all the area forecast offices except Morristown seem to believe it will happen. Morristown seems to be sticking with rain below about 2000-2500 feet on Wednesday.

Anywhere I can learn about this map? Maybe a separate thread? I dont want to get off topic, but this one is a new one to me.
Thanks guys.

(I am back from a 6 month break from the forum, summer was long, hot, and busy.)

I think it's from the Meteocentre website.  I'm unfamiliar with that particular site, but supposedly it shows the Canadian out to 240 hours.

Meteocentre takes the 0z Candaian to 240, while it only takes the 12z to 144

Its my favorite site for the canadian. Everything seems about the same as far as reading it goes with the exception of the heights and thickness lines as they are bunched together and harder to distinguish.
