Pattern December - Deal or No Deal?

Cold chasing moisture = typical SE winter!
That scenario isn’t cold air chasing moisture. It has a low associated with it in the gulf into South Georgia and South Carolina. It’s a classic look for snow in North Alabama, Mississippi and Tennessee.

If it doesn’t show snow in NC/SC, we toss! o_O

Shows mid 50’s/60’s east of the mountains with a snow to the west up through MS TN KY. Idk how we get cold air in place with a cutter pattern. I’m not sure it’s possible. We need blocking, they said. What are we blocking? 60’s from leaving the SE?
 
Looks like for folks to the east to have a shot we need that front end cutter to work itself all the way through before the GL gets going? Looks like a pipe dream. Any experts care to explain

From a general perspective I think that scenario is in dire need of a strong high pressure system to the north. As its currently modeled there's just no cold air in funneling in. That's what I'm going to look for in future runs. Maybe it's in ensembles....

Several problems. One is pronounced SW flow aloft before this system arrives putting a good chunk of the SE in a warm flow aloft.

The 5H energy here needs to dig more than shown, instead it makes it to about Texas and then tailing energy over Colorado "kicks" it to the NE causing a cutter. Generally you want this 5H energy passing along the Gulf Coast region for a widespread SE snow threat (assuming there is enough cold around to work with).

Interesting tidbit in there.

The vertical atmospheric energy transfer looks active to me for the foreseeable future. This could lead to a significant or major stratospheric PV as early as the second half of December and extending into early January.

Lol, all I keep hearing is the models keep showing a vortex under attack. Which one is it?

Need some spacing on that energy as it comes down the pipe. These kickers are gonna continue to cause LPs to cut. Like rapid fire
 
18z is even warmer! Trending in the wrong direction!! Must , stop. Looking ... at.... Op .....Runs!!
I definitely agree... I do think so far this winter is going to be how consistent will the operational models do because like it or not regardless how great the forecasters say how good the upcoming winter season is going to be... It will not matter if the gfs,euro cmc,gfs-fv3,gefs, jma or all other models don't start showing something in the short or long range with consistency... Also I'm still trying to figure out if this is really a modoki or weak El nino... I'm still trying to learn every aspect of weather

The 2m anomalies looked to be colder in total on the GFS I may be wrong tho. Also I know we diss the FV3 but someone posted something the other day showing its accuracy and in the short mid and long range it was close to the Euro and the gfs was almost the worst
 
They look like hell . But the weeklies suck . They will look 100 percent different Thursday

If they were cold I would still say the suck . Been saying it for years

You are right about them being different. They got even warmer since their last run. Complete trash.

Let’s see how Weeklies verify. Xmas week and first week of 2019.

But yeah, it’s U G L Y

Christ almighty. All I know is we have had a favorable pattern and cold temps for several weeks now and you would think this would be rinse, wash, repeat kind of deal just like every single other winter we’ve ever known. Slow and steady, people. Slow and steady
 
People need to realize we are in late November and most of our snows don’t come until January or February. I’m not sure why everyone here is jumping off a cliff based on the weeklies or monthly models when their verification has been absolutely horrible and they have no consistency. Recent ninos have favored a seasonal to warm December here in the SE and the sustained cold will likely set in by late December to early January.
 
Past 3 winters have been AN for the southeast. We may suck but we don’t suck bad enough to go 4 years in a row.

Call us Carolina Gamecocks, we go 0-5, like nobody’s business, against Clemsux! I’m looking forward to a warm December! I can get my lawn well manicured , for the amazing Jan/Feb snows we have coming!
