Carol Kirkwood urged BBC Breakfast viewers this morning to be careful following a yellow weather warning for fog issued by the Met Office. The BBC forecaster said drivers on the M3, M4, M5 and M40 should take extra care this morning. She said: “For the next few days the forecast is mostly a cloudy one. There will be some dimmers of sunshine but as we head through Wednesday and Thursday and Friday, there will be a bit more cloud.
“It will be largely dry, and I say largely because some of that cloud will be thick enough to produce some rain.
“This morning though, the Met Office has a yellow warning out for some fog patches for southern England and Wales.
“Expect poor visibility, it’s patchy fog but we’re currently seeing other fog forming across parts of the Midlands and also heading down towards the south-east and East Anglia.
“If you’re travelling in any of these routes this morning, or the minor routes as well, do take extra care.
“Some of the fog will just lift up into low cloud.”
The Met Office has also warned that the mercury will drop to a freezing -7C (19.4F) in some places throughout the night before a chilly morning.
Forecasters have predicted that the decrease in temperature will be set against the warmer temperatures of Iceland’s Reykjavik, Moscow in Russia and the capital of Finland, Helsinki.
The weather agency has said that in terms of temperatures a north-south divide will be seen.
As the northwest will experience around 10C (50F) in contrast to the bitterly cold conditions elsewhere.
In some areas, police told drivers to “crawl along” icy roads, regardless of whether they will turn up to work as a result.
According to The Sun, the Met Office’s branch in Devon and Cornwall issued a stark warning surrounding the dipping temperatures.
They said: “Road surface temperatures are at -5.1C (22.82F) and still forecasted to go down lower.
“Drive with care, ice possible even on gritted roads.”
