Severe weather warnings have been issued for sleet and snow in parts of Scotland over the weekend.

The Met Office issued yellow warnings for the west of Scotland and Dumfries and Galloway on Friday evening and into Saturday morning.

Up to four inches (10cm) of snow is expected to fall on high ground across Strathclyde, Dumfries and Galloway and Lothian and Borders. Strong winds are also forecast.

Slippery conditions are also expected once the snow melts. The Met Office said this brought "the risk of disruption to transport, especially on higher level routes".

STV weather presenter Jo Farrow said: "There will be snow showers for eastern Scotland tonight and through Saturday but it is the strengthening winds combined with the snow showers, which have led to a Yellow warning for snow from the Met Office due to possible impacts.

"Blowing snow, several cms of lying snow for Friday evening traffic and people on the move first thing on Saturday.

"Met Office warnings are now impact driven. It will be a cold night across Scotland with sub zero temperatures, could dip to around -10C , ice and a widespread frost, but also this feed of snow showers coming in from the North Sea

"This feed continues through Saturday but Sunday looks more settled but cloudy."

The Met Office said: "Showers of sleet and snow will turn more persistent during Friday evening and overnight, leading to snow accumulations of 3-6cm above 200m, with as much as 10cm above 300m, where there will be some drifting in the strengthening winds.

"Some temporary, local accumulations of snow to low levels are possible, though these will tend to melt as things warm up during Saturday morning and rain starts to dominate.

"Slippery conditions are likely, along with the risk of disruption to transport, especially on higher level routes."

The chief forecaster added: "Snow showers driven in on a strong, cold north-easterly wind will line up in places to give accumulations, especially during Friday evening and night.

"During Saturday morning, a gradual warming trend will turn things more to rain, though snow will continue on hills."
