Motorists are being warned of dense fog by the Met Office that could cause commuter chaos this morning.
The UK enjoyed glorious sunshine on Tuesday but temperatures tumbled overnight and it has been a frosty start for many areas of the country this morning with mist and fog.
The Met Office issued a yellow warning stating: “Patches of dense fog are expected this morning.”
The advice covers the east of the country from Newcastle down to Lincoln and will run until 9.30am. It includes East Midlands, north east England as well as Yorkshire and Humber.
The Met Office added that people can expect “slower journey times with delays to bus and train services, delays or cancellations to flights.”
Met Office forecaster Clare Nasir said: "It is going to be a chilly night with temperatures dipping down to 2C to 4C but even sub zero across some glens of Scotland.
"And certainly a chilly start here away from the west coast of Scotland where the temperature will hold up with that breeze but lots of blue skies descending from the Shetlands right the way down the country.
"We may run into some mist and fog even across Northern Ireland and patches extend down over north England."
BBC weather forecaster Ben Rich agreed: “High pressure still close by on Wednesday, it stays mostly dry and with those clear skies overhead. Quite a chilly start to the day with temperatures down to around freezing and below freezing in a few places.
"One or two early fog patches around too, they should tend to lift and clear by the early part of the morning and then it is another beautiful spring day with lengthy spells of sunshine and the vast majority will stay dry."
BBC weather also states: "This morning will see any fog patches quickly lift and clear to another warm and bright day across the UK. There will be plenty of sunshine with just the chance of the odd shower in the afternoon."
Sunseekers lapped up plenty of rays up and down the country on Tuesday with the highest temperature recorded in Porthmadog, in North Wales, on the hottest day of the year so far.
And it is expected to hit 21C again on Wednesday thanks to the high pressure system over the country for the coming days.
Mr Rich continued: "There is just a small chance of one or two showers popping up in north east Scotland and maybe in the eastern counties of England. Not as breezy as it was on Tuesday across western areas but every bit as warm with top temperatures 16C to 20C or even 21C.”
Temperatures are then expected to drop again on Wednesday night to around freezing and fog patches could appear on Thursday morning.
