Snow showers will affect the north of Scotland on Thursday and during Thursday night, initially across Shetland but then quickly extending south to the mainland through the morning. These showers will be most frequent across the Northern Isles, the North Highlands and northern Aberdeenshire. Accumulations of 2 to 5 cm are possible in places on low ground, with 10 to 20 cm possible on higher ground. In addition strong northerly winds will lead to some drifting with blizzard conditions possible at times over high ground.
Icy conditions may also develop on some roads on Thursday night and Friday morning.
The public should be aware of the potential for disruption, particularly to travel. This updates the alert originally issued on Monday.
The deep low pressure passing to the north of the UK on Thursday will usher in a cold, showery airstream of Arctic origin across northern areas, with frequent snow showers feeding in to north and northeast Scotland for around 24 hrs. Higher pressure will return from the west during Friday and cause the showers to ease before a return to milder conditions again into the weekend.
