The Yellow Warning states: "Heavy showers, which will become thundery in places, are expected to develop quite widely across parts of England and Wales later Friday morning and through the afternoon.
"A few places could receive 20-30 mm of rain within an hour. As is the nature of showers however, some places within the warning area will miss them altogether, and have a dry day."
