Approaching Storm

It was 35C in the valley at 4pm this afternoon but the forecast said it would drop to 23C by 5pm. I think this approaching storm might have something to do with it.
We are home now without seeing any rain but there is a lot of grumbling going on.
I'm off to babysit in an hour so hope it has passed by then.


PS. Immediately after posting this the storm hit. 
I've heard of hailstones the size of golf balls but never seen any before. Have a look at the extra.
Fortunately there weren't many of them so no damage done, here anyway.
