I prefer to think of these beasts as 'sitting' lows.
They sit over the country for 5 days or more, only gradually filling.
Heavy showers 'merging into longer spells of rain,' slowly rotating
around them.

Horrible weather.

Fair enough, but in these situations especially when the lows centre is over
your location, I've seen some beautiful cloud rotation in some of the
heavier showers
and enjoyed watching scud clouds being sucked up into the cloud base.
Beautiful.
Cant rule a few funnel clouds out either.
