    Changeable this week. Turning drier through the weekend.

    This Evening and Tonight:

    Breezy tonight with clear spells and occasional showers moving through, these could be heavy at times and merging into longer spells of rain for a time overnight. Staying mild with the brisk winds. Minimum temperature 7 °C.

    Thursday:

    Largely dry with sunny spells though the odd shower still possible. Turning cloudier into the afternoon with more persistent rain arriving by the evening. Winds easing. Maximum temperature 16 °C.

    Outlook for Friday to Sunday:

    A spell of rain will move through on Friday. High pressure then building in over the weekend to bring a settled picture with sunny spells and lighter winds.
