The Met Office has issued a weather warning for snow and ice in Northern Ireland.
The yellow warning is in force through Thursday night until 9am on Friday morning with higher ground more at risk of snow.
However as temperatures fall there is a significant risk of ice on roads.
The warning states: “Rain and hill snow will affect Northern Ireland later on Thursday evening before moving into parts of Scotland and northern England during the early hours of Friday.
“Over ground above 200 to 300 metres snow is expected to accumulate, especially over Scotland where there is also a chance that snow could fall to lower levels for a time.
“As this rain and snow moves away, especially from Northern Ireland, skies will clear allowing temperatures to drop and icy patches to form on untreated surfaces.”
Motorists are advised that rain, snow and icy patches could lead to some travel disruption.
