Brits are set to wake up to dense fog with a weather warning in place for a huge swathe of the country and freezing -5C temperatures.
Stargazers were able to get amazing views of the Wolf Moon, the first full moon of the year, with clear skies up and down the country on Monday night.
But it was only a brief gap in the fog, which returned in the early hours of Tuesday morning and sparked a yellow weather warning for much of England, going right up the east coast and also into Wales.
