I had to come into London today, so I won't get chance to fit my studs... On the other hand, at the moment, the forecast is claiming +2 or +3 and cloudy for tonight so it might not be too bad (famous last words?).
I'm pondering the options...
EDIT: "Showers throughout, heavy and quite frequent in places, perhaps turning wintry at times, with a little sleet or wet snow possible for a time away from coasts. Winds easing for a time but a brisk northeasterly setting in by morning." doesn't sound overly pleasant though...
