Pulses of showery rain running northwards across Ireland and W Scotland on Friday, and overnight close to SW England and W Wales, could produce a few isolated lightning strikes - the risk appears greatest in N + W Ireland on Friday daytime, aided by low-level convergence in an environment with reasonable shear. However, profiles appear rather moist with a warm bulge at ~850mb that could hinder surface-based convection (but foster elevated convection).
