Active Met Office warning

Yellow: Thunderstorms and heavy rain may lead to some disruption — A band of thunderstorms and heavy rain will move north across England and Wales, perhaps becoming slow moving in the afternoon and evening. Accumulations of 20-30 mm in three hours can be expected fairly widely and up to 50 mm in a 12 hour period can be expected in places. There is a small chance that some places may see more than 50 mm in three hours and more than 75 mm through 12 hours, especially over east facing high ground. Lightning and hail of 1-2 cm will also be hazards.
