Upper low and collocated surface low will drift east across central Britain during Thursday, the colder air aloft associated with the upper low will bring a pool of steeper lapse rates eastwards across England and Wales through the day, supporting scattered convection / heavy showers.
A short-wave trough in the base of the upper low will track east across southern Britain, creating a corridor of stronger forced ascent, enhancing instability, this will be the focus for stronger and more organised convection moving inland - with risk of thunder, lightning and hail. Otherwise, away from coasts where instability be greater over sea surface temperatures, there is a more isolated risk of thunder amongst scattered showers spreading across England and Wales.
