York, England, United Kingdom Severe Weather Alertstar_ratehome

Information on update: Area expanded, mainly across southern England, to cater for showers persisting into the evening and overnight period in some areas, leaving wet surfaces in places. 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 and southwest England 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.

A band of snow will move across the warning area through Sunday morning. Across northern England this will mostly be confined to ground above 200 metres elevation, but across Scotland this could fall to low levels during the morning, before becoming increasingly confined to higher ground through the afternoon.

Whilst not all areas may see accumulating snow at low levels, 2 to 5cm is likely, perhaps locally 10 cm. Above 200 metres elevation 10 to 20 cm is possible, perhaps locally up to 30 cm on hills exposed to the strong southerly winds, and over the highest parts of Scotland. Strong winds will lead to some drifting of the snow, and widely icy conditions are likely.

Amounts of snow will depend quite heavily on both elevation and the intensity of precipitation, and as the band pushes east through the afternoon, it will begin to transition to an awkward mix of rain, sleet and snow. Therefore there is likely to be a lot of variation, even over relatively short distances.
