... IRELAND / NORTHERN IRELAND / W SCOTLAND ...
On the forward side of an upper trough, strong deep layer shear overlapping some marginal instability (along or just behind the waving cold front) may be sufficient to allow a few scattered showers / weak thunderstorms to develop during Thursday afternoon / early evening. 

... SW ENGLAND / WALES / MIDLANDS / NE ENGLAND ...
Ongoing (low) risk of some elevated convection on the forward side of the frontal boundary within a higher WBPT plume during Thursday, as several pulse of showery precipitation from medium/high cloud bases nudge NE-wards - some evaporating before reaching the ground.
