Don't forget, Chris, that it's mostly guesswork; based on science, but still
guesswork.
Our weather guessers have the reason for the weather as a strong jetstream
waving from Canada and putting the CONUS to the south of it and the UK to the
north. You get the dry weather, we get the very heavy downpours, almost
monsoon-like in their intensity.
It was only recently that I worked out why TAFs have probability levels only up
to 40% (PROB40 TEMPO etc . . .): it's because 50% is virtual certainty in
forecasting terms, so there is no point in giving a level of assurance above
40%.
We are definitely in strange weather systems.
