RAIN, sleet and snow is expected to spread eastwards towards Lincolnshire during Boxing Day evening before clearing overnight.
Some uncertainty surrounds how much snow will occur, but several centimetres of snow is likely even at low levels, especially in a swathe through Wales and the Midlands, where there is the potential for an amber warning. As precipitation clears, roads could turn very icy.
The public should be aware of the potential for disruption from snow.
A depression will track southeastwards across England and Wales during Boxing Day, clearing southeast England overnight.
A spell of snow is likely, even to lower levels, on the northern flank of this depression. South of the depression centre, rain will fall, heavy at times.
Where snow does occur accumulations of 2 to 4 cm are likely even to lower levels, with more than 10 cm on high ground. There is the risk of 10-15 cm, even at low levels, parts of Wales and the Midlands being most at risk.
