Pimm's O'clock

What on earth happened to Cardiff weather today?! A hailstorm which lasted all day, settled like snow and looked like polystyrene balls on the pavement. And gale-force winds that broke my umbrella. And a bizarre burst of thunder in the middle of the day. What the?
We had a mulled wine/Winter Pimm's and mince pies Christmas party this evening, which was so fun and really lovely. I LOVE Pimm's!
