I used to have bookmarked a site that showed the current and forecast
300mb jet stream, I think it also had an animation option,
unfortunately I lost it with my crash. If anyone thinks they may know
the link, could you please post it on this group?

Many thanks

Probably not quite what you're after but charts e and g in section 1 should
be of interest :-
