Have had thunder pass through here (Eastern side of East Kilbride) for at least half an hour or so so far, last 15 mins the thunder was constant with about 5 secs between each rumble.
Still a pretty grey day here though the sun has tried to break through a few times. Now need all the lights on and it's weird outside (waiting for a thunderstorm type of weird).
Some amazing pictures on this Facebook page taken on Lewis.
