The Met Office has issued a yellow warning of ice for the Western Isles, valid from 4pm this afternoon until midday tomorrow.

Ice is likely to form on untreated surfaces especially where showers of sleet, snow and hail occur. 2 to 4cm of snow may affect low lying areas of Scotland, with 5 to 10cm over higher ground. 

Elsewhere, 1 to 2cm is locally possible.

This may lead to the risk of disruption with difficult driving conditions and expect longer journey times. 

A cold north to northwesterly airstream will maintain the risk of wintry showers through Friday night and Saturday morning. However, amounts of snow are likely to be very variable with some places remaining dry altogether.
