The departing upper trough on Wednesday will be close enough to the British Isles to help generate a couple hundred J/kg CAPE. While instability will be weakening throughout the day, and convective depth reducing, strong shear on the rear side of the upper trough may be enough to compensate for a few isolated lightning strikes from the most intense showers.
