Orographic forcing combined with an upper-level disturbance may allow one or two isolated but locally heavy showers to develop over NE Scotland late Thursday afternoon / early evening, moving NE-wards offshore. Forecast profiles suggest convection may be a little stunted in depth somewhat, so questionable as to how much (if any) lightning activity there will be.
On Thursday night, a mid-level dry intrusion atop very moist low-level air may encourage some mid-level instability release as showery outbreaks of rain develop along a pre-frontal trough, primarily from the Irish Sea across Cumbria / NE England and perhaps S Scotland. Skinny CAPE profiles and somewhat limited depth of convection suggests any lightning activity should be fairly isolated.
