Shivering UK braced for more snow
The latest falls will be triggered by moist air from the Atlantic meeting cold air already over the country.
Matt Dobson, forecaster with MeteoGroup, the weather division of the Press Association, said: "From mid-morning there is a risk of snow in south east Wales, then the Midlands, across to parts of East Anglia."
He continued: "There are likely to be falls on higher ground, but even on lower levels there could be a covering in some areas.
"It's another blast of winter, which will be followed by a bitterly cold night going into Friday in the areas that are affected.
"There is also the chance of more snow at the weekend, particularly on Sunday, especially in the Midlands."
There is likely to be rain south of the M4.
Many areas had wintry conditions on Wednesday, with snow showers in western Scotland and as far south as the Peak District.
The South East enjoyed some unaccustomed warmer temperatures, with readings of 9C (48F) recorded at Kew Gardens and Northolt, west London.
