Between 00:05 Fri 8th and 18:00 Sat 9th

During Friday, increasingly frequent snow showers already affecting parts of Scotland, Northern Ireland and northern England will extend across many other northern and western parts of the UK. 2-5 cm of snow is likely fairly widely, with 10-20 cm in places, mainly northern Scotland, Northern Ireland, north Wales and perhaps the northwest Midlands. Icy surfaces are also likely to be an additional hazard, especially overnight.

The heaviest and most frequent snow showers will progressively become confined to northeast Scotland during Saturday. Possible travel delays on roads stranding some vehicles and passengers with possible delays and cancellations to rail and air travel. Some rural communities could be cut off and power supplies interrupted. Probably some icy stretches on some untreated roads, pavements and cycle paths. Some injuries from slips and falls on icy and snowy surfaces. This warning has been updated to extend east to include more of the Pennines.
