Snow tonight - or not

The weather forecasts for tonight present some interesting contrasts.  See the screenshots below all taken about 1545 this afternoon:
  1. The BBC (Met Office) predict 12 hours from 9pm tonight to 9am tomorrow with heavy snow, bracketed before and after by 3 hour periods with light snow
  2. Accuweather are predicting rain with cloudy periods
  3. Netweather give no snow before 9pm with a 30-38% probability of snow from 9pm tonight and a 30% to 45% chance of very light snow after 9am tomorrow.
Update 10:30am 08.01.11
 1.  BBC/Met office:  70% acccurate - the snow came though not quite on cue and they over egged the 12 hours with heavy snow.
2.  Accuweather:  30% accurate -predicted precipitation about right but it was rain, not snow.
3.  Netweather:    50% accurate - precipitation was about right but the probability of snow was on the low side. 
    Let battle commence. . . .
