The Met Office has issued another weather warning of snow and ice for Derry.
The latest warning is valid until 10:00am on Wednesday.
The north could see thunder and snow, according to the Met Office.
"Further showers of snow, sleet and hail will affect western parts of the UK, these frequent in western Scotland and the north of Northern Ireland, where thunder is also possible," read the warning on the official Met Office website.
"One to three centimetres of snow may accumulate at low levels inland, and perhaps five to 10 centimetres on hills above 200m.
"Showers will gradually fade overnight Tuesday into Wednesday, with icy stretches developing as skies clear, particularly where earlier snow has partly melted.
"As is usually the case with showers, some places will miss them, while some coastal fringes may see rain or hail."
