The Met Office has issued amber weather warning as up to eight inches of snow could pelt the UK this week.
The rare weather warnings are in place for snow for parts of northern England and North Wales on Thursday.
Up to 25cm of snow is forecast across the Peak District and the southern Pennines, with a warning in force from noon until 6pm.
A separate warning for snow and ice is in place between 8am and 3pm across North Wales and Shropshire.
The Met Office said an amber warning means travel delays on roads were likely; public transport vehicles and cars could be stranded; power cuts were possible; rail and air travel delays were likely and rural communities stood a “good chance” of being cut off temporarily.
Temperatures will drop as the week goes on, with a yellow snow warning issued which covers much of Wales as well as northern and central England, the Met Office said.
“A band of rain, sleet, and increasingly snow, will push north on Thursday bringing up to 2cm snow at lower-levels, 2-5cm on ground above 200m, and perhaps as much as 10-20cm above 400m,” the Met Office said.
