I have noted from looking at the weather archives that notable anticyclonic spells during February have a tendency to favour retrogression. As always, there are exceptions to the rule. Interesting the retrogression happens late in the month.


Some examples.


According to Philip Eden, the three most anticylonic Februarys since 1880 are 1932

Thanks for posting these - great to take a look at past scenarios. Whilst I do not discount pattern matching completely, I think our current high cannot behave the same as any of the previous examples simply because we currently have a less amplified pattern with an unrelenting strong Northern arm of the jet.


My personal view is that there will be a pattern re-set from the South West with a much milder interlude towards the end of the month.  After that who knows what could happen in March we can often be a chiller.
