Snow and sleet showers hit the UK on Tuesday, but the Met Office has warned there is colder weather to come.
Wednesday is expected to be the chilliest day of the week, with northern areas waking up to temperatures of minus two degrees Celsius (28F). Coastal areas can expect more snow and sleet showers throughout the day.
The Met Office has issued a yellow severe weather warning for ice across much of the country.
The alert says that ice is likely to form on Wednesday morning, warning of the risk of falls on icy surfaces and ice on roads, pavements and cycle paths.
A Met Office spokeswoman said: “Northern Ireland saw some significant accumulations this morning, probably a few inches, then it pushed across Wales, central parts of England and towards the south east.
“We’ve seen a few centimetres in particular over the hills, but also a good dusting of snow to lower levels as well.
“Most of that has cleared away now, with the exception of eastern Kent, where there could be further snow showers overnight.”
The spokeswoman added: “Tomorrow will be one of the coldest days of the week, but with a lot of sunshine to compensate.
“Those concerned about the yellow warnings should allow extra time for journeys and take extra care on untreated roads and pavements.
“It’s patches of ice left over from snow showers that people should look out for.”
Although the weather will warm slightly towards the end of the week, more cold weather is set for the weekend.
The spokeswoman said: “Gradually some slightly warmer air will push in for the latter part of the week, but we have a band of rain pushing in Saturday which will push much colder air in behind it.
“By Sunday it will be very similar conditions to those we will have tomorrow.”
