Outbreaks of rain will develop through Thursday evening and night, becoming prolonged and heavy throughout Friday, before slowly easing into Saturday morning. Strong easterly winds will accompany this rain. Accumulations of 30-50 mm are expected quite widely, with some places receiving 60-80 mm, and potentially in excess of 100 mm over east-facing hills in southeast Wales. This, following recent wet weather, could lead to some surface water and river flooding impacts. Although some uncertainty exists in the areas of heaviest rainfall, impacts appear more probable across southeast Wales, the Midlands and parts of southern England.
