Nonetheless, there is reasonable agreement that behind the slow-moving cold front, sufficient insolation will generate enough instability, given cold mid/upper levels and steep lapse rates, to allow a few scattered showers and weakly-electrified thunderstorms to develop - these perhaps most likely over the W Country / Midlands / CS England / Home Counties. Some small hail will be possible with this activity, which will tend to diminish through the evening hours as daytime heating subsides. Given the uncertainties in exact positioning / timing, no SLGT has been issued at this time.

Later in the night, deep convection will tend to develop more widely across the western half of the English Channel, with numerous showers and perhaps a few weakly-electrified thunderstorms brushing close to the coast of south Devon / Cornwall during the early hours of Thursday.
