Outbreaks of rain, sleet and snow will move north over mid and north Wales and northern England on Tuesday evening and Wednesday morning. Snow accumulations, in the order of 1-3 cm will mainly occur above around 200 metres, though the odd cm is possible at lower elevations. There is also a chance of transient freezing rain over higher ground and though the odds of this occurring in any one location is small, but would increase the ice risk nonetheless. Sleet and snow will clear from the south through Wednesday morning. For further details see https://www.metoffice.gov.uk/weather/warnings-and-advice/uk-warnings
