Cool air aloft associated with a shortwave moving NE-wards on Thursday will generate several hundred Jkg-1 CAPE when combined with diurnal heating - however, probably slightly out of sync (too fast) with the diurnal cycle, with a peak in potential around early afternoon over eastern England, and reducing from mid afternoon for most areas except NE Scotland where the pivoting trough will clear slowest. Nonetheless, a few scattered showers are likely, perhaps weakly-electrified, focussed along areas of wind convergence (such as peninsula convergence from SW England - East Anglia) but probably fairly isolated given quite dry profiles.
