He added: "While not all areas will have fog, where it does form the visibility could be less than 100 metres.

"Combined with temperatures below freezing, there is also the risk of ice forming on some untreated surfaces particularly later in the night and early on Thursday morning.

"The fog patches are expected to slowly thin during Thursday, although some patches may persist throughout the day - most likely in a zone from the West Country to Eastern England."

Temperatures would rise to around 6C, he said, but could be closer to 3C throughout the day.
