I'm currently witnessing an unusual trend; my annual mean for my location continue to climb slowly but steadily at a time when it's usually falling. This has been known to happen for a run of a few days at a time in years past, but this year it looks like being the case for pretty much the whole first half of the month and perhaps beyond!
If my local monthly mean finishes at more than 11.04*C then there will have been the first Oct-Nov rise in my records. Typically over the past 15 years the annual mean has fallen about 0.5*C from Oct to Nov.
The mean to Oct is higher than 2010, 2012 and 2013 but lower than all the other years going back to 2000. Yet to November it could end up higher than 2004, 2005, and perhaps 2009 at a stretch (11.09*C). There can be no catching the 11.54*C of 2011 though, let alone the 11.95*C of 2014!
2011 and 2014 were 1.6*C and 0.7*C above the LTA in December respectively, so it would take something truly incredible to bring 2015 much closer after this month has passed. But to end up more than halfway up the pack having been so close to average for the first 10 months would be quite a feat.
Here's a fun fact - if this month continued to be about as mild through to the end, my minimum temperature anomaly would be around +7.0*C and max anomaly around +4.0*C. I've known subtropical-sourced air to bring mid-teens temps in December (as have many of us) so technically that is achievable should the Azores Low/Euro High pattern keep recurring with barely a pause for breath in between each round.
