Sunday will bring a mix of cloud and sunshine, though with cloud generally increasing through the day.

Highest temperatures again of 9 to 12 degrees in light to moderate variable or westerly winds.

However, it will turn less cold overnight as cloud continues to increase from the west. Winds will become southeasterly and they'll increase fresh to strong in parts of the west and southwest, with rain pushing from the west too, becoming heavy at times, though it will hold mainly dry in some northern and eastern counties. Lowest temperatures early in the night of 1 to 7 degrees, coldest in the east.
