Some heavy thunderstorms running through the southwest this morning, looks like it's gonna be a muddy one
Thing about Glastonbury - you have to take into account the weather leading up to the weekend - and we've had a pretty dry sunny early summer, so the ground will be relatively moisture free.
So as long as it don't rain consistently for the next three days, they should have a goodun.

I've never been one of the 'mud doesn't spoil it' types - there really is NOTHING like Glastonbury Festival in the baking hot sunshine - stumbling round what is effectively a benign shanty town in shorts, sandals and a drug induced haze used to be the highlight of my year - but when it's wet, you have to plan every outing like a military operation, and it kind of takes the shine off.
