High pressure will build across the British Isles for many days, the resulting subsidence / dry air aloft will largely suppress any deep convection. Some shallow fair-weather cumulus cloud may develop in response to diurnal heating, perhaps very locally capable of producing an isolated shower, but for many areas it will remain dry. No lightning is expected.
