The Met Office has issued a yellow warning of snow and ice affecting all the Strathclyde area next week.
Frequent hail and snow showers are expected from Monday evening, continuing throughout Tuesday.
There is expected to be over 10cm of snow falling above 200 metres, and even at low levels there could be up to 5cm, possibly accompanied by strong winds and lightning.
A Met Office statement said: “Travel delays on roads are possible, with a small chance of cancellations to public transport.
“There is a small chance that power cuts will occur and other services, such as mobile phone coverage, may be affected.
“In addition some roads and pavements may become icy, increasing the chance of injuries from slips and falls.”
