Weather could be a 'significant hazard' on higher roads
There's the possibility of up to four inches of snow on higher ground later, according to the Met Office.
Showers are due this evening and at first tonight, which will be heavy at times.
This is likely to be rain, hail or sleet at lower levels, but will fall as snow or hail above 1,000ft.
There's a warning that as the showers move away later in the night, and as skies become clear, icy stretches will develop on roads above about 700ft, which could be a significant hazard.
