British Isles...
Within the upper ridge, local spots of slightly augmented LL moisture and convergent LL flow are found where some low-end CAPE may be created by diurnal heating. As vertical shear is almost zero in most of these places, storms should be poorly organized and severe weather is unlikely. One can't rule out an isolated hail / wind gust event but this is likely below the level 1 threshold.
