he first book about the weather that I had was by the Bartlett brothers -
this must have been about 1948. I think it was called " Signpost to the
Weather" . Sadly, I think I binned it many years ago. The most interesting
feature of it was a broad brush forecast for each month , broken down into
4 week periods( which Keith mentioned)- most of which I have forgotten. The
only bits I remember were that cold spells were forecast for the middle of
both January and February with unsettled weather for the first and fourth
weeks. I think the cold winters of the early 1940s probably influenced them.
I enjoyed reading Keith's item about them, most of which I didn't know.
They also wrote for the' London Evening Standard'

It sounds like they might have been influenced by the work on
singularities, adapted for the UK from the German original by CEP
Brooks. I seem to recall the singularities for January and February
indicating the likelihood of spells as described above.

The trouble is is that the climate has changed and any old relationships and
singularities are unlikely to be valid anymore, some may still work but basing
forecasts on old relationships when the climate has changed won't be reliable.
Sorry, but people must really accept that things are different now. I know you
have Paul !
