Cold air sweeping in from the Arctic is set to bring frosty conditions to North Wales this weekend - with snow a possibility in highland areas.

The chilly snap will bring an end to the largely mild start to autumn, with people advised to dig out their warm winter clothes.

No warnings have been issued by the Met Office for Wales - unlike areas of Scotland and Northern Ireland - but temperatures are set to dip with snow forecasted to dust the hills in Snowdonia.

Met Office meteorologist Aidan McGivern said: "Snow building up over the higher routes, some icy patches for the north of Scotland as well as Northern Ireland to watch out for first thing Saturday.

"It will be a fairly chilly start, with temperatures widely close to freezing and that means you'll perhaps have to scrape your car windscreen and you'll see a frost in place first thing."

Gritters are on standby across the UK, with a number of councils posting pictures of their fleets online.

Met Office forecaster Bonnie Diamond added: "We have had a pretty mild October so far and a warm start to autumn in places so it will be a big change for everybody as we go through the weekend.

"Certainly it's time to get the warm winter clothes out."
