Atlantic upper low slowly drifts towards western Ireland during Saturday, maintaining a feed of cold mid-levels atop warm seas around the British Isles, steepening lapse rates and generating 400-800 J/kg CAPE. Numerous showers are likely over open water, these then moving inland to exposed southern and western areas. Organised troughs / occlusions will push showers well-inland at times, and where such features become aligned with the steering flow may result in consecutive showers training over similar areas and hence the potential for localised surface water flooding - particularly southern coastal counties of England, but such convergence lines may extend well-inland too.
