    Warning

    Isolated heavy, and possibly severe, thunderstorms are expected to develop on Friday evening across parts of southern and southwest England. These are likely to become more frequent later and spread northwards across Wales, the Midlands and northern England overnight, and into southern Scotland by the early hours of Saturday. Some torrential downpours are possible leading to localised surface water flooding, with hail, frequent lightning and squally winds also likely hazards.

    The public should be aware that there is a chance of some very localised significant disruption.This is an update to the warning to extend the yellow area across southern Scotland and elevate the position in the risk matrix. This will be kept under review and further updates are possible closer to, and during, the event.

A list of all UK Warnings can be found on our More UK Weather page.
