The Met Office has issued a Yellow Warning for heavy snow for Wednesday and Thursday.
Two to three inches of snow is expected over lower levels with four to six inches possible over higher ground.
Gale force winds will accompany the snow showers, creating blizzard conditions.
The Met Office’s Chief Forecaster said: “An active cold front is expected to push southeast across the UK during Wednesday, introducing an increasingly cold and unstable air mass.”
“Showers will become frequent and heavy, falling as snow and driven well inland by strong to gale force northwesterly winds.”
