Main interest during this forecast period is during the early hours of Friday morning, as the Atlantic upper trough swings towards Ireland / western Scotland, the associated cold air aloft atop relatively warm SSTs generating a few hundred J/kg CAPE. Numerous showers will develop over open seas, moving inland on the strong southwesterly steering flow. A few isolated lightning strikes will be possible from the most intense cells.
