The Met Office has issued a yellow weather warning of snowfall in some parts of England and Scotland.
The weather forecasters also warned of possible interruptions to the power supply as well as transport delays and road closures.
A tweet from the weather experts reads: “An amber snow warning has just become valid for parts of northern England and central and southern Scotland
“Heavy snowfall can cause disruption, especially over the hills, with transport delays from impassable roads and possibly some power cuts.
The snow is expected to fall at 3 p.m. today and continue until 10 a.m. on Thursday morning.
Paul Gundersen, Chief Meteorologist for the Office, said: “There is cold air from the north pushing the east side of Britain down and warm air from the west. Where these two air masses meet a weather front, it brings heavy rain, which in places turns into snow. “
The rain will turn to snow at high levels this afternoon, but increasingly to lower levels.
The snow risk will extend south to the north of England tonight.
10 to 20 cm of snow could accumulate in the warning area over 200 m, and in some places in lower elevations there could be 5 to 10 cm of snow by Thursday morning.
The Met Office predicts the snow will gradually stall by tomorrow afternoon.
A yellow weather warning for snow and ice has already been issued for Saturday.
The warning covers large parts of Scotland, as well as northern and central England.
