Elsewhere, attention also turns to parts of England and Wales during the afternoon/evening with modest surface heating yielding a couple hundred J/kg CAPE. Profiles suggest the potential for low-topped convection with >40kts cloud-layer shear and some backing of the low-level winds. A substantial dry intrusion will overspread a moist low-level profile. The net result is line segments could evolve, spreading northeastwards with time, capable of producing squally winds and perhaps a few lightning strikes - but the latter aspect is uncertain given the limited depth of convection. The strong low-level shear (speed and directional) suggests at least the threat of an isolated tornado across Wales, the West Country and the Midlands, should any substantial convection be able to develop.
