Today

Mist and fog patches will clear this morning leaving a mix of cloud and sunny spells and a good lot of dry weather with just some rain and drizzle in the northeast and isolated showers otherwise. However, rain and drizzle will spread up from the south and southeast in the afternoon and evening, extending northwestwards, to mainly affect south Leinster and Munster. Highest temperatures of 5 to 10 degrees in light, occasionally moderate, easterly or variable breezes.

Tonight

Mostly cloudy tonight with scattered outbreaks of rain and drizzle. Lowest temperatures of 4 to 9 degrees for Ulster and Leinster, 2 to 6 degrees for Munster and Connacht with the best of the clear spells. Northeasterly winds will be moderate along northern and eastern coasts, but will be mostly light and those light winds will allow mist and fog patches to develop.

Tomorrow

Mostly cloudy tomorrow with some outbreaks of rain and drizzle and with mist and fog lingering in places, mainly in the west and in the midlands. There'll be some good drier intervals too, though any bright breaks will be limited. Highest temperatures of 6 to 11 degrees in mostly light easterly or variable breezes, moderate though in coastal parts of the east and parts of the south.
