People in Wales woke up to another cold and frosty start to the day.
Temperatures dropped to -4°C in Monmouthshire at 7.02am on Tuesday morning, but this is the last day of the sub-zero weather.
Tuesday is going to be a dry and crisp day with plenty of sunshine, but cloud that is going to move in overnight will raise temperatures.
Met Office forecaster Bonnie Diamond said: “Tuesday night into Wednesday will be a lot cloudier and that means it will be less cold that what we have been experiencing since the weekend.
“There will be some hill fog around in Wales on Wednesday morning and it will feel cold, but there won’t be the same widespread frost that we have been experiencing.”
The cold weather froze signalling points at Treherbert station on Tuesday morning meaning that trains between there and Pontypridd were not running for several hours.
Motorists were also warned about driving in icy conditions.
But it is set to change from Wednesday.
Bonnie added: “We will be saying goodbye to the sunshine as it will be a lot cloudier and foggy as the week goes on.
“There might be some periods of brightness in Wales on Thursday, but it is generally going to be cloudier with patchy, light rain.”
Met Office forecast for the rest of the week:
Patches of frost and fog may be slow to clear through the morning. Elsewhere should see some sunshine through breaks in the cloud, although the north is likely to remain overcast. Maximum temperature 9 °C.
A milder night than of late, with fog patches reforming through the evening. There may be the odd spot of rain or drizzle through the early hours. Minimum temperature 0 °C.
Patchy drizzle on Wednesday with some hazy sunshine. Hill fog and low cloud could become fairly established and linger for much of the day. Maximum temperature 11 °C.
Outlook for Thursday to Saturday:
Remaining cloudy and murky on Thursday and Friday with the odd spot of rain. Saturday is likely to see the return of wet and windy weather, with potential coastal gales.
