Winter wonderland plunging temperatures bring snow to Northern Ireland
This was the picturesque scene on the Mourne Mountains yesterday as the latest cold snap bit - and there could be more snow to come.
Temperatures plummeted over the weekend, leading to a touch of snow on higher ground and there are some more wintry showers forecast for later in the week.
Today it is expected to stay below 7C, but it will feel colder throughout the day.
Motorists, pedestrians and cyclists are advised to be careful, particularly when travelling on untreated roads or pavements.
Although there will be some bright and sunny spells, there will also be some showers across Northern Ireland and it is expected to get windy in the afternoon.
According to forecasts, an area of high pressure means it will remain chilly throughout the week and there could be some snow from tomorrow onwards.
There will also be rain and strong to gale force north-easterly winds on Tuesday, but it will settle down later in the week.
Weather throughout the UK is expected to be cold and many in England and Scotland are also bracing themselves for sleet, snow and widespread frost.
Mel Harrowsmith, head of civil contingencies at the Met Office, said: "For many the weather during the coming week is likely to be the first experience of winter, with either frost, wintry showers or even snow affecting many areas of the UK."
The weather in the third week of January is likely to be slightly milder as Atlantic systems try to push across the country, bringing rain and strong winds.
