I'm not going to lie, this month has been frustrating for me from a CET perspective. Just a week ago it was looking likely to finish in the mid-5s i.e. near average due to a return of cold nights this weekend just gone, continuing through this week.
Instead it has remained very mild with colder weather pushed back a few days. Despite the final 3-4 days of the month adjusting a bit colder, the end result looks likely to be a much higher final CET, somewhere in the low to mid-6s.
Overall, the MJO has behaved as I anticipated and this has led to a SSW much as expected - but this is one of those occasions where it makes a huge difference precisely when the CET stops going up and starts going down. Seeing which way the patterns will shift is one thing but getting the timing right is quite another! I will concede that I underestimated just how mild it was capable of becoming this month, even setting a daily CET record on 18th as Retron highlighted.
The March estimates should make for interesting viewing this year if current model and teleconnection-driven signals hold 👀
