The last three hours' readings show a marginal rise in temperature, humidity and wind speed and a fall in barometric pressure. The moon is now shrouded in cloud but still visible in an "it's about to precipitate" kind of way.
The temperature forecasts over the next couple of days, which will see Monday creep up to about 2°C makes me think this will last a bit longer than the normal westerly snow-turned-to-rain scenario, but Tuesday sees temperatures of 4°C so I'm not sure that it's worth fitting my snow tyres. I can always postpone Monday's teaching session until the end of term.
