Partially thawed snow during Friday will likely freeze overnight as temperatures fall below freezing, leading to a widespread ice risk. In addition, wintry showers will continue to feed into parts of Wales at times, perhaps also into the West Midlands. Whilst there is some uncertainty as to the extent of any precipitation, this falling onto frozen surfaces may also add to the risk of ice. Freezing fog patches are also likely in places, posing an additional ice hazard. For further details see https://www.metoffice.gov.uk/weather/warnings-and-advice/uk-warnings

Information on update: Extend the warning north through parts of Cheshire. Rain, associated with Storm Goretti, will continue to spread northeastwards across the warning area through Thursday evening, transitioning to snow fairly widely overnight and into Friday. Snow initially will begin to accumulate across hills in Wales and then increasingly to lower levels overnight. Whilst not all areas may see accumulating snow, accumulations of 5-10 cm are likely quite widely, with scope for 15-25 cm in places, especially on some hills above 200 metres elevation. There is a chance of 30 cm accumulating over high ground in Wales and/or the Peak District. Amounts of snow will depend quite heavily on both elevation and the intensity of precipitation, and as this becomes somewhat lighter into Friday this will lead to an awkward mix of rain, sleet and snow, gradually clearing away to the east. Therefore there is likely to be a lot of variation, even over relatively short distances. For further details see https://www.metoffice.gov.uk/weather/warnings-and-advice/uk-warnings
