I find that the ForecastBar weather app is incredibly accurate. I set off for a 30k spin on the bike after lunch with thunderstorms forecast for an hour later. Sure enough, I'd just got home and the sky darkened in minutes and we had violent thunder and lightening for about half an hour before it all blew over and it was nice again.
Busy this morning, Bike this afternoon and then family for a chat in the evening so this is my only photo of the day. At least it's quite atmospheric!
