December warm NOT White

The others are closely bunched together. Just crazy.

 

That's the normal distribution of record monthly highs with each new high only a few tenths to a degree above the 

previous record. We are seeing an extreme climate event here similar to March 2012 where MW stations beat their

previous warmest march by 5 degrees or more. The 2000's keep finding new ways to be extreme.

Using the GFSx for the next 7 days:

Actual sums of all the highs and lows through the 24th.   is   1371   +    1105   =   2476/48  =  51.6 degs. avg. so far.   Adding in the 7 day projections of the GFSx:    1734  +  1421   =   3155/62   =   50.9 degs. as the estimated final result.

 

Thus, it is as if we got stuck back during the first week of November and never made any progress at all.

 

Now this 50.9 would be +13.6.   Currently record is +6.8 and I am guessing that this previous all time record represented 4.3 Sigmas---which the all time monthly and annual records probably do in relation to the 30 year norms in effect at the time the record is set---except of course right at the start of record keeping in 1869.     So we have here an 8.6 Sigma Event with odds in the millions to one of happening by chance alone, if you are going to accept the current 30 year normal and that no instrument or human errors were involved.

Case Closed.   Welcome to our New Brave World of Climatology.   

Perhaps if I get the time I will create a July analog to this month.   That will stop the giggling HOT in its tracks.

The NYC December departure is now at +13.1 which is 51.6 through the 24th.

 

Previous top 5 way behind

 

44.1...2001

43.8...1984

43.6...2006

43.3...2011

43.2...1998

48.5 here so far...warmest was 41,8 in 2006. This has probably been mentioned but this would rank as one of the warmest NOVEMBERS...still a week to go to see where we ultimately wind up.

Statistically, this is a December that is off the charts. Through the 25th, the average LOW at NYC for December (46.5F) would in itself be the warmest December on record (which I believe is 44.1 in 2001)   I have never heard of that ever happening at any time anywhere. That is just beyond comprehension if that holds through the 31st. Truly something historic.

One more chance for record warmth this month on Sunday. NYC is currently at an historic 52 degrees and +13.6

for December through the 25th. December 2015 will finish in a similar class as the exceptional warmth that

occurred in the Midwest in March 2012.

The GFSx is +15degs. for remainder of month, and at +12degs. overall.

After the first 25 days of month:       High temps total  1437   and the lows total 1162    1437 + 1162 =  2599/50 = 52.0 avg. currentlyUsing  Using the GFSx   >>> 1747 +1425 = 3172/62 = 51.2 Final Estimate.

GFSx uses different normals, leads to some confusion.  But final est. should not be affected.
