This Evening and Tonight

Any early evening thundery showers in northern counties will quickly clear. Then a fine evening and night with scattered cloud and light winds. Staying warm and muggy in London and eastern areas, but somewhat cooler in western counties.

    Isolated heavy, and possibly severe, thunderstorms are expected to develop on Friday evening across parts of England and Wales. These are likely to become more frequent later and spread northwards towards southern Scotland. Some torrential downpours are possible leading to localised surface water flooding, with large hail and frequent lightning also possible hazards.

    The public should be aware that there is a chance of some very localised significant disruption
