That's interesting, here on the east end of the US we've had the opposite problem - High of 60ºF and low of 30 one day, high of 30 and snow the very next day.
It's a cracking day here in the mid-south of dear old Blighty... an azure blue sky, fluffy while cloudy things and lots of smiley faces .. especially on rugby fans.. Kinda makes me glad to be alive.
