A statement from the Met Office said: “Heavy showers and thunderstorms are likely to break out on Friday afternoon and evening.
“Many places will miss the storms, but where they do occur, torrential downpours could bring 30-50mm rain in a hour, with hail and lightning.
“The storms will slowly clear northeastwards on Friday night, perhaps not clearing north east Scotland until Saturday morning.”
