Synopsis

A complex area of Low pressure, "Doris", becomes centred over southern Britain on Wednesday, dominating the weather across the United Kingdom.

South of a quasi-stationary occlusion, located over northern England and Northern Ireland, numerous showers and local thunderstorms are expected to develop as a result of daytime heating and instability. Showers may form a NE-SW aligned line as part of a weak convergence zone during the afternoon hours, with the greatest threat of electrical activity most likely across the north Midlands southwestwards into east Wales.

Light winds will ensure that any showers are slow moving, in a predominately WSW direction. There is the potential for a weak convergence-type funnel possible. Showers will generally decrease in coverage during the evening hours, particularly after sunset.
