    Wales weather forecast

    Headline:

    Rain clearing to sunshine and showers. Mostly fine by Sunday.

    Today:

    A band of wet and rather windy weather will feed eastwards across the country this morning. Much sunnier skies will follow during the afternoon, perhaps with isolated showers developing later, and the brisk winds will ease a little too. Maximum temperature 15 °C.

    Tonight:

    A few showers are possible in the north and west overnight, otherwise dry with clear spells. Lighter winds, allowing a few fog patches to form, and staying frost-free. Minimum temperature 6 °C.

    Saturday:

    A day of sunshine and well scattered, mostly light showers is expected on Saturday. Feeling fresher thanks to a west to northwesterly breeze, though pleasant when the sun appears. Maximum temperature 14 °C.

    Outlook for Sunday to Tuesday:

    After a chilly start both Sunday and Monday look dry with light winds and some sunshine. A cooler northeasterly wind on Tuesday giving more cloud and the odd shower.
