Atlantic upper trough will continue to dig towards Biscay, becoming increasingly negatively-tilted while slowly approaching the British Isles from the southwest. A couple of frontal boundaries will become quasi-stationary over the Celtic Sea and portions of Ireland, with renewed pulses of rain running N / NW-wards along the fronts. Embedded convection seems likely at times, in an environment with a few hundred J/kg CAPE - and hence there will be an ongoing (low) chance of a few isolated lightning strikes. Of greater concern is the risk of localised flooding in southern Ireland, where heavy bursts of rain may become prolonged at times.
