Yellow weather warning for snow now on Thursday and Friday as well
Chief Forecaster's assessment
Snow showers will be heaviest and most frequent across western Scotland, where high ground is likely to see a further 10-20 cm building up above 200-300 metres. There may also be more than 15 cm over the high ground of Northern Ireland and northern England. At low levels, parts of the warning area will see 3-10 cm of snow, with some places near the west coast seeing 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. Strong winds bring the potential for temporary blizzard conditions and drifting of lying snow, mainly over high ground. https://www.metoffice.gov.uk/public/weather/warnings#?date=2018-01-19
