    London & South East England weather forecast

    Headline:

    Evening rain and strong winds easing. Breezy with showers Sunday.

    This Evening and Tonight:

    Rain moving east through the evening, perhaps tuning heavy in a few spots, before clearing East Kent around midnight. Clear spells follow, and likely turning dry for all. Blustery winds also easing for a time. Minimum temperature 11 °C.

    Sunday:

    Sunny spells and showers, isolated at first but becoming more frequent by the afternoon. These could be heavy and blustery times, with the odd rumble of thunder. Winds strengthening again. Maximum temperature 22 °C.

    Outlook for Monday to Wednesday:

    Sunny intervals and showers each day, these often heavy. Chance for a spell of more persistent heavy rain Tuesday, clearing Wednesday. Blustery winds likely, especially Monday. Temperatures near normal.
