Wednesday will see heavy showers in the evening, ahead of a risk of localised flooding on Thursday.
It will begin rather wet and windy today, especially over much of the north and east, with overnight rain largely confined to east Ulster by late morning.
Sunny spells and scattered showers will then follow from the west, some heavy, especially this evening.
It will be blustery and cool with highest temperatures of 9 to 13 degrees.
