The Met Office has issued a yellow weather warning for snow and ice this evening.
Rain will gradually turn to sleet and snow this afternoon on the hills, above about 1200 feet, before clearing away this evening.
Accumulations will be mostly above road level, with anything settling on the highest roads slight.
However, with clear skies developing as the evening goes on and overnight, road temperatures on high level routes will fall close to or slightly below zero, giving a risk of ice (above approximately 800 feet).
