The Met Office have issued a severe weather warning for Saturday 19 July.
Areas of heavy, thundery showers may develop over England and Wales from Friday night before moving northwards into Scotland later on Saturday. The development of these is uncertain but where they do form some torrential downpours are possible with frequent lightning, large hail and locally strong gusts. Significant flooding is possible where these do occur from surface water as well as small, fast responding watercourses. The frequent lightning, large hail and strong gusts could also be an additional hazard.
