The gulf stream collapse/diversion is a regional (NW European) issue on times scales of a century.
The increase in weather persistence is a short term, i.e. already happening to an extent, effect relevant to all northern mid-latitudes.

I'd need to do the same analysis, but on a 50 year timescale.

(really hate these 300 character limits.)
There's a prediction of climate change: increasing polar heating leads to slower jet streams and more persistent weather. That is, if it is dry, it stays dry for longer. If wet, it stays wet for longer.
An effect between weather and climate timescales.

What is an interesting statistic to look at, which I've never seen anyone do, is if there has been a change in the amplitude and duration of these swings.

I'm not using last year as a baseline. Edinburgh's mean annual precipitation is around 750mm, and there's not much reason to believe Pencaitland is much lower than that.

And today are you getting drowned in rain? Big slow moving storms in your area.

Could be, if the winds picked up. Solar is providing close to half the energy needs of the UK, according to Kate Morley (IAmKate.com). But the winds would just blow all those photons out to sea.
Probably giving a big boost to skin cancer, if we want to be miserable about the sun, which we seem to
