Synopsis

A shallow area of Low pressure over northern France will dominate the weather across the country on Saturday.

Widespread scattered showers and thunderstorms are forecast to develop over many parts of central, southern and eastern England as instability increases during the morning, these moving in a (on average) southwesterly direction into SW England and Wales during the afternoon.

Given the rPm airmass, hail is likely in many of the showers, and in stronger cells the hail may be moderate to locally large in size, accompanied by torrential downpours. There exists the potential for funnels or a weak tornado to develop. Showers will decrease in coverage from the northeast as a ridging occurs, with virtually all parts dry by the end of the evening.
