Synopsis

Complex area of Low pressure "Quendeline" (FU Berlin) situates itself across the United Kingdom, dominating the weather on Wednesday.

Overnight heavy rain and thunderstorms associated with the cold front continue to drift across the North Sea during daylight hours towards Scandinavia.

In the Returning Polar Maritime airmass, numerous showers and thunderstorms are expected to develop as instability increases, aided by daytime heating, these mainly across central and western Britain and most of Ireland. Showers/storms may perhaps become locally severe in nature, with gusty winds, moderate-sized hail and a chance of a weak tornado, particularly over Wales and western England.

The showers/storms are expected to decrease in coverage during the evening hours, becoming mainly confined to the coasts overnight where the thunder/lightning risk continues.
