First snow falls in Northern Ireland
Northern Ireland has seen it's first full taste of wintry weather with many parts of the province getting significant snowfall overnight
The Met Office had issued an ice and snow warning over the weekend for parts of England, Scotland and Northern Ireland.
Snow settled mainly on high ground, with low-lying areas seeing heavy sleet and rain on Sunday night, through to Monday afternoon.
The colder conditions will move Southwards for a time but will return on Wednesday and Thursday, accompanied by gales in the north.
Weather forecast service MeteoGroup warned that conditions across the UK and Ireland are turning unsettled over the coming days as a deep area of low pressure forms in the North Atlantic, leading to a "powerful" storm.
Looking ahead to the coming week, a spokesman for the Met Office said: "We're expecting the first real cold blast in these parts. We will see snow on the hills, and in the south of England perhaps some sleet and hail."
Scotland will be the worst-affected region, with around 10cm or more of snow expected on the country's mountains. The spokesman commented: "Across the tops of the Scottish mountains it will be pretty horrendous."
The Met Office spokesman said it was too early to predict a White Christmas.
He added: "It does look as though the unsettled weather theme will continue, but we can't really pin down any detail about the actual weather type on Christmas day itself. At this stage it's still a long way away before we could give precise detail."
