I have found a good website showing the jetsteam and where it will be situated over the next week or so ..... I think it should be over the UK (ideally over Scotland) for us to have nice weather? According to this website it is over us again and has not slipped down over France, which is good news as we go away on holiday next week! :)
The jet stream is a handy pointer to the weather patterns in general but to make accurate forecasts
about the local situation we need to know lots of other information. That site is fun though so thanks.
