Another freezing fog warning from the Met Office has brought further travel chaos fears across the UK.
The yellow warning has been issued from 2am to 11am tomorrow and covers much of eastern England.
However, the weather agency says the severe conditions could cause major delays from tonight.
It comes as Britain battles through a winter cold snap which has seen temperatures plummet lower than -10C in recent days and heavy snow fall in parts.
Snow and ice warnings have already been issued earlier this week - including a rare amber one - due to the ongoing Arctic conditions.
A separate yellow warning for freezing remained in place until 11am today for parts of England, with freezing fog already making driving conditions difficult this morning.
The Met Office warns there could be delays to journey times by car, as well as possibly bus and train services.
There is also a chance of cancellations of flights.
Manchester Airport was forced to close both its runways for a period due to heavy snowfall.
Drumnadrochit near Inverness in the Highlands hit minus 10.4C in the early hours of Thursday, making it the coldest recorded temperature of the year so far.
Over the weekend, conditions were expected to get milder with the mercury possibly reaching double figures next week.
But the respite from the cold will potentially be short-lived as forecasters now fear another wintry snap is coming in next month from Greenland.
