OK, this weather is officially mental. Half an hour ago it was snowing. Five minutes ago the sky was a blinding blue, sufficient for myself and a colleague to pause by a window and remark upon its hue. Then within thirty seconds of our conversation the sky was again completely white with snow. Now? The sun is shining and the sky completely clear.

On my way home form work I will be on the look out for fist-sized hailstones, rogue wolves on ships and that pretty one who ended up with Gyllenhaal.
