    Wales weather forecast

    Headline:

    Dry and bright Friday. Rain arriving Saturday.

    Today:

    Isolated showers first thing on Friday morning, but these will soon fade as a ridge of high pressure builds in. This leaves brighter spells in the afternoon, especially in the west. Light winds and temperatures near average. Maximum temperature 20 °C.

    Tonight:

    Dry with clear spells initially. However, it will cloud over from the north after midnight. Strengthening southwesterly winds, with a risk coastal gales across Gwynedd and Anglesey later. Minimum temperature 8 °C.

    Saturday:

    A band of cloud and rain already across north Wales will gradually sink south across the country during the day. Some heavier bursts possible. Rather windy, with temperatures near normal. Maximum temperature 20 °C.

    Outlook for Sunday to Tuesday:

    Dry with variable amounts of cloud around on Sunday, before another area of rain arrives from the west for Monday. Turning rather showers on Tuesday, with a risk of thunder.
