An area of snow is likely to persist across northern Scotland during Wednesday, spreading down the east coast through the day. This falling as rain or sleet at low elevations, especially around coasts, but is likely to fall on to frozen surfaces, bringing the potential for widespread icy conditions to continue. A further 5-10 cm of snow is likely to fall fairly widely over higher ground above 100 m, but there is a chance some areas above 200 m could see a further 20 cm. Strong winds could lead to continued drifting or blowing snow in places. Accumulations over lower elevations, coastal areas, and over Orkney and Harris are expected to be lower, but ice is expected to remain a hazard on Wednesday morning and again on Wednesday night, particularly where snow melts during the day and refreezes overnight.

Information on update: The likelihood of impacts has increased, particularly across central and northern mainland Scotland. An area of snow is likely to move east across central and northern Scotland during Tuesday. Freezing levels may temporarily lift for a time, allowing snow to turn to sleet or rain at lower elevations, before lowering again, with further snow showers likely returning to northern Scotland by the evening. A further 2-5 cm of snow is likely to fall fairly widely, but there is a chance some areas could see a further 10-15 cm, particularly over higher ground above around 200 metres. Accumulations over the Northern Isles are expected to be lower, but ice is expected to remain a hazard on Tuesday morning and again on Tuesday night. Precipitation is likely to fall on to frozen surfaces, particularly during Tuesday morning, bringing the potential for widespread icy conditions to develop.
