Here is a comparison of the winter 2019/20 CET temperature against the top 7 warmest winters in the series (which all had a winter CET of above 6.4C). The data uses my estimate out to the end of January.

My suggestion is that after adjustments we may be looking at 6.3 give or take a tenth or 2. GW will no doubt have his own finely calibrated prediction, though we all know all predictions are only as good as the forecast data inputted.

With it being such a big anomaly, it will be particularly impressive result this month for those who have made a decent call (say, within 0.5*C of actual) on just how anomalous to go, considering the sensitivity of extreme month 'attempts' to temporary switches away from the dominant weather regime.


Imagine, for example, if the current high pressure was either further northeast (colder and for longer), or southwest (barely cold to begin with). There's probably well over 1*C of difference between those two scenarios.


 


So, if Gusty does turn out to have it nailed or very nearly so, it will be quite some 'icing on the cake' (...decorated with crystal balls).

Yes, it certainly looks like Gusty is off to a good start, although I think we’ll end the month a little below his prediction.  Oh, hang on!  What do I know?  


My February guess is already in, as I’m off to cruise the Far East for two weeks in temps above 30c.  Coming home will be a shock to the system! 


Good luck with your January predictions - note I refer to mine as guesses and everyone else’s as predictions.

The seventh is 1686 at 6.33.


In any case, how can we compare these to winter 2019/20 which is only just past half-done?

A cooler interlude incoming, but not massively so, followed by a mild rally for the final day.


Perhaps not much overall change from where we are now, prior to adjustments from the provisional.


 


Had a sneaky look ahead to Feb. Signs of a sudden stratospheric warming to try and shake things up, but no strong indication of the type of event that's most likely to bring a big cold spell to NW Europe; the kind where two areas of warmth from different origin points join forces to 'pinch' the polar vortex in two.


Instead, a displacement with possible subsequent split is being indicated. We saw that last Jan-Feb and it didn't serve us much cold weather - just the one spell in the south that did, at least, bring some appreciable snowfall. It then helped set up that record-warm spell at the end of the month!


 


The 12z GFS begins extremely balmy for Feb 2020; CET of around 9.0*C for 1st-3rd which is over 5*C above the LTA to that point in the month. There are then some cool or chilly interludes but separated by more very mild spells, with the CET estimate only just out of the 7s *C as of 11th.


So even if we saw the right sort of SSW, it'd have a lot of work to do if that run is anywhere near the mark. Other modelling (ensemble & long-range) has generally supported the mild theme, even very mild.


Unless we see a big change in model signals in the next five days, it's going to be hard to go for anything other than above average again .
