Showers are expected to turn to snow across parts of northern Scotland during Wednesday morning, the risk then transferring to other areas through the rest of the day, continuing overnight and for much of Thursday.
Across Northern England 3-8 cm could accumulate by Thursday morning, especially over high ground. Over Scotland and Northern Ireland 5-10 cm may fall even at some lower levels, with more than 15 cm possible over higher ground. Strong, gusty winds will lead to drifting and temporary blizzards over high ground, while icy surfaces and lightning pose additional risks in some areas.
This is an update to extend the warning a little further south across the Pennines. Note also that there is some signal that more frequent snow showers may affect parts of southern and central Scotland through the evening peak travel period on Wednesday, and this may lead to eventual issue of an Amber warning.
The public should be aware of the potential for disruption to travel.An active cold front is expected to push southeast across the UK during Wednesday, introducing an increasingly cold and unstable air mass. Showers will become frequent and heavy, falling primarily as snow and driven well inland by strong to gale force northwesterly winds. Commuters and other travelers seem likely to face a variety of winter hazards, especially later on Wednesday and early on Thursday, although it's likely that snowfall in some areas may be more patchy, particularly towards the east.The public is advised to take extra care, further information and advice can be found here: http://www.metoffice.gov.uk/public/weather/warnings/
