SNOW RETURNS: Snow is likely over higher ground across Powys above 300 metres overnight and into Thursday morning.

The Met Office has issued a Yellow Warning for snow from 4am to 11am tomorrow.

A spokesperson for the Met Office said: "An area of rain and snow will remain over Wales into Thursday morning.

"Snow is most likely above 300 metres where around six cms of snow may lie, particularly on east and south east facing slopes.

"Snow may fall down to around 200 metres but at this level it is unlikely to lie on roads.

"Any lying snow is expected to thaw during Thursday afternoon."

Some roads and railways are likely to be affected with longer journey times by road, bus and train services.
