Michael Dukes, director of forecasting at MeteoGroup said the cold snap was due to remain for "some time yet".
There has been a band of sleet and snow moving through parts of the east Midlands, east England and south east England late in the night, towards morning.
It has produced only one or two centimetres in places, it is not very much. Most of the snow has been on higher ground but there has been a little bit of snow on lower ground as well.
