"There is also quite a strong northerly wind so that gives a bit of an extra cold feel to the weather.
"Then for tonight the winds will gradually ease and showers will die out and what will happen then under clear skies is it starts to get very cold.
"There will be widespread frost and temperatures down to -2°C inland and that frost will clear tomorrow morning."
