In weather terms the start of summer (June 1st) is just two weeks away. Looking out the window this afternoon that’s hard to believe.

We’ve got persistent rain and wind on its way this afternoon and evening in London – in Wales there’s even a chance of some snow.

So what’s going on?

Well the position of the jet stream is largely to blame, as the Met Office explains:

At the moment the jet stream is sitting directly over the UK. It’s in the same position it was for much of the exceptionally wet June last year.

But it’s not all doom and gloom as the jet stream is not stuck in one position and is liable to move with just a few days notice:

In the short term things are looking pretty unsettled. It will be blustery again tomorrow but a sunnier afternoon with isolated scattered showers.

More of the same on Thursday and Friday before I looks like it will turn wet and windy again on Saturday (though the weather 5 days ahead is liable to change).
