damn the 12z eps is cold

I wonder if my gas bill will be as astronomical as my electric bill during August.
 
12z eps supports the idea of the euro with a day 8-12 system but that's way out there . But there are some fun looking members

I just don't understand how they are calling this an arctic outbreak. Highs in the 40s, lows in the 20s is cold but shouldn't it be a little bit colder than that to be considered arctic ? One guy on the local news said there's a lot of snowpack in Canada so the air wouldn't have any time to modify, and i'm thinking to myself if that was the case wouldn't it be a lot colder than forecast ? I think the local meteorologists are making way too big of a deal out of this.

we live in the southeast we are not gonna get the highs in the single digits to below zero like the midwest.

It's an arctic outbreak we catch the edge of it not the core

if this isn't an arctic outbreak I don't know what is

[/quote] Well I know that, but i've seen plenty of arctic outbreaks with highs near freezing.

if seen plenty with highs in the 20s , they are all different as you know . But the variations don't change the fact they are arctic outbreak

I'll take that and run with it. Especially considering the last few Decembers.

euro ensembles and gfs ensembles are in agreement with a system the 16th-18th. Looks to be the first widespread threat of the season especially for Arkansas,Tennessee and NC

Considering that every December since December 2011 has been a torch it really wouldn't take much for this to be the coldest first half of December since 2010. Temps could be AN the first half of Dec and still be the coldest since Dec 2010.

That's what I was thinking, too. That turned out to be a good December and winter. I remember before the Christmas snow that year there were a couple small threats that we tracked.

How did the individual members and mean look? I know the GFS had 18 showing something here.

This is realistically the coldest first half of December since 2010

1) Good point. I'll go one further and say that there is almost no way that the first half of Dec. of 2016 won't easily be the coldest for the SE US as a whole since 2010.

2) ATL is about to have its single coldest Dec. day since 2010 and its biggest negative daily anomaly at least since Feb. of 2016. That is quite significant. However, a fair number of folks really only care about wintry precip., which is normally hard to get in Dec. (especially the first half). ATL has had only ~10" of SN/IP in total over the last 100 years in the first half of Dec., meaning an average of only 0.1"/first half of Dec. or only 5% of its total seasonal average. During that time, there was a major sleetstorm in 1918, the last time there was a major ATL DEC SN or IP. So, it is good to be realistic so as not to get hopes up too high. ATL has also had a couple of significant to major ZR's in the first half of Dec., but even that doesn't pick up in historical frequency til the last week of the month.

[/quote] When was the last time if EVER, that ATL had a major snowstorm in the first half of December ? I've lived in GA my entire life and never recall even seeing snow on the ground before Dec 15. So really, any cold before Dec 15 in GA is wasted cold air.

[/quote] I would complain if it were hot the second half of December, but the first half of December no matter how cold it is we literally never get snow or ice so its basically pointless.
