Temperatures plunged as low as -4C overnight. Clouds were likely to move in bringing with it some patchy drizzle in some areas across the South West.
However, the region is expected to have milder weather in the coming days. From Monday to Wednesday next week it will mostly be dry with sunny spells before the rain hits, the Met Office reports.
The Met Office said: "The cold spell will come to an end later this week and through the weekend across western areas, where it will turn milder and windier with some rain at times." According to its long-range weather forecast, temperatures between Monday, January 23 and Wednesday, February 1 are "likely to be close to or slightly above average overall, especially further northwest."
