The next Atlantic cyclone will gradually deepen as it tracks northeastwards close to the Hebrides during Thursday. Frontal precipitation will affect most parts of the British Isles at some point during this forecast period, with pockets of weak CAPE in places - as such, the odd isolated lightning strike cannot be ruled out. 

Later in the day, and more especially overnight, an upper trough will advance from the west, leading to increased instability and steepening mid-level lapse rates. Showers will affect many western areas, and later in the night southern areas also, capable of produce a few lightning strikes, hail and gusty winds.
