Forcasts of Snow

So anyone noticed why the UK Met Office so routinely predicts snow and then it doesn't arrive?  Really the pattern seems to be this: They forecast snow in a few days time, as you get closer and closer this forecast turns progressively, first to sleet... then to snow?  OK, occasionally they are right, but not often (subjectively assessed!).

Why do they get it wrong so often?
They don't.  They don't forecast wrong... they tell us wrong!!!
It's all about their use of statistics, and specifically that they don't trust the general public to understand the most rudimentary of statistics.
So their weather models will actually say:
Probability of it remaining dry: 15%
Probability of rain/sleet: 70%
Probability of snow: 15%
But they think is too confusing for us... so they have a call of predicting rain/sleet or snow or dryness.  The most likely weather will be rain/sleet but they don't predict that... instead they forecast "snow" even thought it is an outside chance, because they feel that to fail to predict snow will land them in genuine hot water, whereas to predict snow and there be none is, they would argue, no problem for anyone.
So the problem is not their maths or their models... but their lack of confidence in our ability to interpret "15%".
Surely the BBC and the Met Office should get some courage and faith in the general public and give us the actual probabilities that they have: 70% chance or rain/sleet, 15% chance of snow!  Dumbing down communications with the public will be a self-fulfilling prophesy.....
