I found this site a few days ago - it's a weather station run by a school in Coventry. As well as showing the current conditions it also has some statistics and historical weather info:
Bablake Weather Station

Looking at the statistics page I was surprised to see that there were 23 days last year when it snowed - I didn't think it had snowed that often, but it might count some hail (or snail) in with that.
