March 4th – I was going stir crazy. A bad day – the internet was getting me down, the thaw had set in and the world outside had the slimy, grey, filthy wet feel you only get with melting, heavy snow.

I slipped out on an errand at sunset and something magical happened. I caught a surface-air temperature inversion. I saw it start on The Parade in Brownhills, as it was gathering over the common. I raced to Chasewater. It was stunning.

An inversion occurs when the ground is colder than the air above and mist forms is very low, isolated pockets. I’ve not seen on this strong since I was a kid. Mist drifted around and almost deserted Chasewater, and I was in the middle of it, like a kid in a sweet shop.
