A reservoir of relatively cool air aloft, associated with an old shortwave, continues to linger over England and Wales during Friday, slowly clearing to the east. Similar to Thursday, forecast profiles look rather moist but with less in the way of warm noses aloft. Diurnal heating should help yield 400-800 J/kg CAPE, which combined with low-level convergence (and some aspects of orographic forcing) will enable the development of well-scattered showers and a few thunderstorms.
