And then there's a loud, long rumble of thunder. At around 8pm local time. Didn't seem particularly hot or stuffy when I went out around lunchtime to move the wheelie bin before it moved itself (okay, it's not that windy, but the one a couple houses down the road got blown over. It's not been that wet either, just one of those constantly dismal days weather-wise).
Haven't heard another rumble, but all my computer kit is on a surge protector anyway.
You can tell I'm bored - I'm writing about the weather!
