I think Leeds are having sleet! It may turn more to snow when its gets late on and temperatures have dropped. Depends how long quickly/slowly it moves away or fizzles out though.
I think maybe the East will get more accumulations with the heavy showers coming from the Easterly. The forecast is certainly had a change for Yorkshire, higher ground now from 20cm to 10cm with lower levels seeing sleety conditions.
Deputy Chief Forecaster Dan Suri explains whether the UK will get snow this weekend. He also explains why there is uncertainty in the forecast.

Anything can change, anything can happen. Doesn't mean that it will stick being North, it can keep on changing. It could fizzle out and become of nothing.
