It'll be a grey and damp start to the day for most with patchy light rain and drizzle. Brighter conditions will move in from the northwest through the afternoon with some sunshine and it will feel pleasant outside.


Tonight will be dry with some clear spells developing. The westerly wind will be strong along the coast and we'll see the cloud thicken in the west towards dawn.
