Motorists experienced difficult driving conditions as snow and sleet hit the region.
Strong winds accompanied the snow, with gusts of more than 50mph recorded in the west of the region.

At around 10.30am, there was a crash on the eastbound carriageway of the hill, before all lanes were re-opened around 45 minutes later with no serious injuries reported.
A Welsh Ambulance Service spokesman said: “Shortly after 10am, a crew in an emergency ambulance came across a one-vehicle road traffic collision on the A55 at Rhuallt Hill.
“One female patient was given a check-up at the scene but did not require hospital treatment.”
Higher ground was particularly impacted by the snow, with roads such as the Horseshoe Pass in Denbighshire tricky to negotiate.

Back roads were also affected, with one van getting stuck on the back road from Meliden to Holywell due to the slippery conditions.
While snow did begin to clear throughout the day, some residents were left angered at the lack of support during snowy conditions.
County councillor Aeron Jones, who represents Llanwnda, said the bins are not filled by the local authority unless community councils pay them to do so.
He said: “The council grit the main roads but they have refused to replenish the salt bins in the villages.

“This is the case for every rural village in Gwynedd . The policy is they don’t fill them up unless the community council pays.
Gwynedd Council said they experienced “significant snowfall” on higher grounds, but that all major roads were gritted, and that salt bins not being filled would not impact on this.
Two schools were closed in Denbighshire due to the weather conditions.
Ysgol Betws Gwerfil Goch was fully shut while Ysgol Carreg Emlyn in Clocaenog and Cyffylliog was only partially closed.

Forecasters predict the bitterly cold weather could last for the rest of the month and even more snow could be on its way.
The recent cold snap is being controlled by a huge polar maritime air mass from northern Canada and this is expected to be a major influence for some time, according to The Weather Channel.
