Behind the frontal precipitation across southern Britain, an upper low and cold mid-levels will overspread the relatively warm waters of the English Channel / Celtic Sea, generating a few hundred J/kg CAPE. Scattered showers are expected to develop as a result of this increased instability, primarily during Thursday evening and night. Most showers will remain offshore, parts of Cornwall, Devon and SW Ireland having the greatest risk, but will be capable of producing a few sporadic lightning strikes.
