The first snow of the winter could fall later this week, forecasters have predicted.
An Arctic air mass is expected to hit the country by the weekend, bringing an end to weeks of above-average temperatures – and snow.
A Met Office spokesman said: “Heading into the weekend, we could see more in the way of cold air sinking southwards with a mix of sunshine and blustery showers.
“These showers are likely to fall as snow over high ground in the north and there’s a risk of them turning wintry over hills further south.
“Overnight frosts will be increasingly likely, with perhaps some icy patches too.
“There is some uncertainty as to how long this cold spell will last but it is likely that wet, windy and milder conditions will spread back in by the end of November.”
