Extremely wet Novembers: a recent trend?

If the GFS is to be believed it could end up being an extremely wet
November, particularly from the middle of next week. There seems to
have been a recent tendency for very, very wet Novembers, with very
active fronts and thundery showers between the fronts, every 3 years
or so in the last 10 years or so - for example 2006, 2002, 2000, 1997
all following the same sort of pattern.
This differs from how I remember November in the 80s and early 90s,
which tended to be a rather gloomy month with frequent steady, but
never heavy, rain interspersed with foggy periods and the odd frosty
high. November always used to be more "settled", if significantly
gloomier, than October, while these days October, the archetypal
"Atlantic" month, is often settled and can almost pass as a summer
month were it not for the relatively early sunset.
So has this time of year become more cyclonic?

Long term records show that November is the wettest month in some parts of the
country and one of the wettest in most others. A very quick look at the "World
Weather Guide" shows that November is the wettest month of the year in London,
Birmingham and Plymouth based on 30 years of records. It doesn't say which
30-year period.
