Through the afternoon and evening brighter weather will follow from the west and winds will ease.

The last of the overnight rain will clear from the east early in the morning on Friday to leave a day of sunny spells and showers.
The showers will be heavy or thundery with the possibility of hail, but temperatures will remain mild between 9 and 12 degrees, in light to moderate southerly breezes.
