    Headline:

    Changeable next few days, with sunshine and some showery rain.

    Today:

    Early bright spells will give way to increasing cloud from the west on Thursday morning, and this will lead into a wet and quite blustery afternoon. The strongest winds will be around coasts and high ground. Some heavy rain developing. Maximum temperature 19 °C.

    Tonight:

    The heaviest of the rain will clear eastwards this evening, leaving showers for a time, these easing by dawn with some clearer spells. A milder night than the previous night. Minimum temperature 11 °C.

    Friday:

    Isolated showers first thing Friday morning, but dissipating under a ridge of high pressure. This leaves brighter spells in the afternoon, especially in the west. Temperatures will be near average. Maximum temperature 20 °C.

    Outlook for Saturday to Monday:

    More wet and windy weather returns on Saturday, followed by another ridge of high pressure and drier weather on Sunday. Staying autumnal into next week with further spells of rain.
