There might be something in this jetstream thing, yesterday and last night there was a minor loop of it over the UK,  afternoon and night  top two pics below, and today and this evening (when Chris reports good, I cant verify as I am clouded out still ! ) the bottom two, the loop moved off and we are between two 'bits'. On the other hand, it is a poor statistical sample and I've not checked on where the low pressures are currently ! so ymmv
