"The high ground of Northern Ireland and northern England will also see 10-15 cm building up.

"At low levels, parts of the warning area will see three and seven centimetres of snow but some places near the west coast will see very little.

"Showers will be accompanied by hail and lightning at times, particularly across western Scotland. Here, in particular, there is potential for disruption to power supplies from lightning strikes. Winds will strengthen at times, particularly from later Thursday, bringing the potential for temporary blizzard conditions and drifting on hills and mountains."
