Yeah, Happy Hour has an additional Arctic high dropping down. This run has 3 more warm days followed by cold 1/14-18 followed by 3 warm days followed by cold again 1/23-25.
Also, the EPS is trending colder. If things were to keep trending the way of happy hour, any warm dominated period would be delayed even more as that is more back and forth through 1/25. For the record, I have the period 1/16-2/28 warm dominated with at least 2 warmer than normal for the SE as a whole.

I retract that. After looking at the data on whnderground there is a GAp from 1:45 to 5:30 *rolls eyes*. The actual station is showing it bit 58.4. Anywho. Looks like it turns colder again this weekend..

Could someone take time out of their night to make a temperature departure from average assessment on the months of, say, April/May 2017 through the first week of January 2018 for a major city in the southeast such as Asheville Raleigh or Greenville? I'm willing to bet it defies the warming tend we've seen the past 10+ years

It is still not enough data to come to a sound conclusion. The Jan cold outbreak we just experienced was an extreme and will skew such a small data set.

It might would be better to do all the Januarys from the 1940s through 2018 to get more accurate numbers.

Yeah. I was just thinking that we had a very pleasant summer in the south. I guess I was wondering how summer 2017 fall 2017and winter 2018 matches up against the rest since winter 2017 really skewed our numbers last year. Maybe when this winter is over we can do that and it will be more sensible

only a few months fell slightly below normal in 2017 here in CHA... June & Aug were just barely below normal, less than a degree, while July was around +1. Sept was -.1,Both Oct and Nov around +2, Dec started off one week above normal, then the cool spells began. Overall 2017 was AB, but not as much as previous two years. CHA has not had a -2 degree BN month since Feb 2015, which was -8.1. (and I didn't mention climate change once... oops).
 
Wow. 7.6 just struck caribean. Sunami warning puerto Rico. Not what that region needs.

Ok GaWx I'll do this in two posts. I did all of the dates you requested, then I selected six more of my own. Yours first:

2/4/1967
2.4.67.gif

2/4/1973
2.4.73.gif

2/25/1980
2.25.80.gif

3/19/1983
3.19.83.gif

2/1/1984
2.1.84.gif

1/2/1988
1.2.88.gif

2/12/1989
2.12.89.gif

2/19/2015
2.19.2005.gif


Of these, I would say three could be classified as west-based neg. NAO's (2/4/73, 1/2/88, 2/19/2005) and 3/19/83 may have been a neg. NAO a day or two before but I didn't check.

1300,
Thanks very much for taking the time to post these! Of these, 2/4/1967, 2/25/1980, 3/19/1983, 2/1/1984, and 2/12/1989 look like pretty solid west based +NAOs based on the solid cold anomalies dominating Greenland and nearby. So, i don't think their high regularly calculated +NAOs are deceiving. Also, you accidentally posted 2/19/2005 instead of 2/19/2015. If you get a chance, please post 2/19/2015 and/or edit your post.

The 0Z GFS is awfully cold in the SE, especially TN and vicinity but cold throughout, for practically a full week centered on 1/16. It isn't nearly as cold for N FL/SE GA/Carolinas as 1/1-7 but that's because that was historic. That doesn't mean this isn't still repectable solid cold being shown for mid month. The progged mid-month cold keeps getting longer and stronger. If this trend continues and especially if we were to get still another cold shot late month like the Happy Hour was showing (0Z doesn't have that), we could end up with quite a cold January overall.

Goog gosh, fwiw, look at how much less warm is the 0Z GEFS vs prior runs for late month. It is warm for only 1/20-22 before turning colder once more.

Euro was pretty cold too, at 12z... thinking Nina climo is in the back pocket for a moment, at least. Wavy Pacific but still cool climo. January is gonna end up pretty dramatically BN for the SE Us I think.
