North Wales is set for a big freeze in parts overnight as temperatures drop to as low as -5C. Winter conditions are setting in as December approaches, with frost and some snow on higher grounds.

But heading into this evening and tomorrow morning, it's going to get bitterly cold across the region, although there will be a difference in temperatures, with the east generally colder than the west. And the freezing conditions are forecast to carry on into Friday.

Here is where and when we will see the lowest and highest temperatures for this week, according to Met Office maps as of 1pm on Wednesday (November 29 2023):

Tonight:

Clear skies overnight which means it will be turning very cold with a widespread sharp frost, and some icy stretches possible. Mist and freezing fog patches possible too. Minimum temperature -2C.

Thursday:

Another cold and frosty start but largely dry with plenty of autumnal sunshine once any mist and fog clears. Perhaps the odd coastal shower. Staying cold, particularly in the breeze. Maximum temperature 4C.

Outlook for Friday to Sunday:

Largely dry though some coastal showers which may bring flurries of hill snow inland. Some early morning mist and fog around at times and feeling cold with overnight frosts.
