2009 I think it was Susan Powell bbc weather 3.57pm forecast she showed a huge band of rain over northeast France coming up to hit the cold air over the southeast pushing up towards north of London one to watch she said could have 10-15cm at rush hour London are never forget it was due to be around 5-6 o'clock and guess what happened yep rain pure cold rain not even sleet .
So since that day I never watch there forecasts I take all there forecast now witha huge pinch of salt
