Frost and fog will threaten some parts of the country in the coming days.
The Met Office, which has urged everyone to “keep the hot-water bottles ready as it’s going to be a cold and frosty night”, has issued a yellow weather warning for fog for Friday and Saturday – which could disrupt travel.
People in the East Midlands, eastern England, north-east Wales, Yorkshire and the Humber have been told to brace for the thick fog and freezing temperatures.
As nebulae are expected to spread overnight, the warning said “some dense nebulae are possible, with visibility potentially dropping to 50-100m in some places.”
Forecasters say the fog could become quite widespread and perhaps thick, particularly for the central and eastern parts of England.
Poor visibility can lead to dangerous driving conditions in some areas, slower travel times for car journeys and possible delays in bus and train services.
Temperatures will drop to as low as -5C in some rural areas of England and Wales, while regions further north and the far west will remain above freezing due to increasing cloud cover.
