Whilst many places will likely remain dry and unaffected, scattered thunderstorms may develop during Saturday afternoon, lasting through the evening hours, moving northeastwards before eventually clearing to the North Sea by the early hours of Sunday. The most intense thunderstorms could produce frequent lightning, large hail and gusty winds, along with some heavy downpours for a time. This may lead to some surface water impacts in places.
