More wintry weather – including snow in places – is forecast for the UK later this week after temperatures dropped below freezing two nights in a row.
Thermometers plunged as low as -7.7C in Shap, Cumbria, on Friday night and -5C in parts of Scotland on Saturday night.
Many other parts of northern England and Wales also experienced conditions below zero overnight.
Met Office meteorologist Ellie Glaisyer said it would continue to feel “very chilly” across northern and eastern parts of England during the day on Sunday.
It will remain cold this evening but temperatures will be “not quite as harsh” as those seen over the previous two nights, Ms Glaisyer added.

The next few days are forecast to be cloudy and rainy across much of the UK.
A frosty evening is expected in many areas on Tuesday, with temperatures of around -2C to -5C. They could fall as low as -8C in the far north of England and rural Scotland.
Then on Thursday up to 5cm of snow could fall in parts of Wales and northwest England over higher ground.
Smaller amounts may also fall at lower levels too, forecasters said.
Dartmoor, the Pennines and parts of Scotland are also at risk of some sleet or snow.

Many regions are also likely to experience severe frosts, icy stretches and patchy freezing fog.
The cold conditions on Saturday night came as the Northern Lights – also known as aurora borealis – were spotted across parts of the UK.
The colourful waves were reportedly witnessed in the skies above parts of Scotland, northeast England, Suffolk and Essex.
Another phenomenon called Moon haloes – when moonlight is reflected by ice crystals in the air producing a white halo effect – was also seen in areas further south.
