SMEG......
yep, snow flurry in Reading last night, I was on the phone to a buddy in Wokingham and they had it to, and they had it on the M3 at Basingstoke which is close to you too, seems you were just unluck or lucky what ever way you look at it.
I would say it snowed in Stafford last night at 6:30pm, but it was more frozen drizzle. Unless you were looking into car headlights, you could not even see it!
