A little bit of fun before we get into June, but post the date on which you believe the Westerlies will return this year between 1st June - 31st July.

By definition, I mean the Jet Stream kicking back into action & heading directly across the British Isles from either the West, South West or North West, with unsettled weather then persisting for at least the following 5-7 days.

I'm going for the 19th June this year.
