A sudden stratospheric warming (SSW) has seen a rise in temperature and change in wind direction in the atmosphere high above the Arctic.
This happens at an altitude of about 30 km so has a delayed influence on weather at the earth’s surface.
The Met Office said: "A further 1-2 cm of snow is possible in a few places at first, mainly above 200 metres across Scotland, northern and central England, before residual rain, sleet and snow dies out during Thursday evening.
"Ice is then likely to form on some untreated surfaces, with difficult conditions on some roads and pavements by Friday morning."
