Minus 6C in West Midlands as freezing fog hits transport
Freezing fog played havoc with travel today, with flights cancelled, roads jammed and delays on main line rail and Tube services.
And forecasters warned that although warmer conditions were on the way, they would be accompanied by heavy rain.
The worst of the fog was lifting during the morning, with Heathrow having earlier cancelled around 60-70 flights.
London City Airport also had to axe six early-morning flights, as UK temperatures dipped as low as minus 10C (13F).
In the West Midlands temperatures dipped to minus 6C (21F) overnight but warmer weather is forecast from Friday and over the weekend, when temperatures are unlikely to fall below freezing.
