There's some really confusing stuff coming out of the Met Office this afternoon.

There's a forecast of snow for tomorrow for the Peak District yet the Mountain
Weather Forecast for the Peak District issued at 1712 today gives a probability
of precipitation of only 10 percent for Tuesday morning and zero percent for
Tuesday afternoon.

Also, for Wednesday there's currently a severe weather warning in force for
Derbyshire for heavy snow showers yet the Peak District forecast for Wednesday
says "dry with variable cloud".

It's all a bit confusing and raises questions about quality control
