A low-pressure system will develop across the west of Ireland on Wednesday, introducing a warm Theta-E plume to the eastern parts of England during the afternoon. This will provide energy for convective showers to develop, boosting the amount of CAPE (around 300 J/kg) across southeastern England. This might allow a few clusters of thunderstorms to develop from France, perhaps extending across East Anglia; therefore, a slight risk has been issued. Moderate shearing and an unsaturated profile could allow one or two storms to be long-tracked.
