Snow set to settle over 'wide area'
Up to 3in (8cm) of snow could fall in parts of the UK as the big freeze continues.
Forecasters have warned of dangerous conditions on the nation's roads caused by freezing rain. The latest treacherous weather comes after three people died in sub-zero, icy conditions in the north of England this week.
Nick Prebble, forecaster for MeteoGroup, the weather division of the Press Association, said: "There will be a problem with freezing rain in the morning which is going to start causing problems in southern Scotland and northern England. It will spread south east, and as it moves will turn into sleet and snow."
The cold front will move to North Wales and Yorkshire, hitting the Midlands by the middle of Thursday afternoon, he added.
Mr Prebble said: "From midday onwards, there will be snow falling, with between 4cm (1.6in) and 8cm (3in) possible. The areas worst affected are likely to be East Yorkshire, Lincolnshire and the East Midlands.
"There may well be snow flurries in London by the evening. It looks like it is going to settle in quite a wide area."
Sub-zero temperatures are set to continue for much of the UK over the coming days, with the mercury struggling to get above 0C (32F). Temperatures reached minus 12C (10.4F) in Church Fenton, North Yorkshire, on Tuesday night.
The Met Office has issued a level-three severe cold weather alert lasting until Saturday and has warned of icy roads across much of the UK.
Award-winning cheese-maker Mandy Reed, 47, was found dead in a snowy garden near her home on the edge of the Yorkshire Dales in the early hours of Sunday morning.
In Hull, a man believed to be in his 50s was found dead in a park near Woodland Road earlier this week. In Castleford, West Yorkshire, Joshua Houlgate, 10, was found collapsed outside a friend's house on Sunday after going out to play in the snow.
