The snow will not stick everywhere as the ground is not cold enough in November. But as the snowfall risk eases for many the extra moisture will refreeze. Ice is then likely to become the main issue in bitterly cold Arctic air.
A brisk northerly wind will continue to drive further wintry showers into northern Scotland and through North Sea and some Irish Sea coasts. As much as 10cm (4in) of snow could still settle on higher ground with 15-20cm (6-8in) possible above 300m (1,000ft) in the Highlands.
As the winds lighten in inland areas through the night ice will form on untreated surfaces, causing more potential transport disruption into Wednesday morning’s rush hour.
There will be a widespread frost across the UK. With clearing skies tonight temperatures will fall well below freezing, with -2C to -5C widely.
Last night Braemar in the Highlands plunged to -11C which is the lowest this early in the season for more than 25 years.
We could see something similar in sheltered northern spots again tonight, especially over lying snow.
