Weak ridging will generally dominate across the British Isles on Friday, although the slack surface pattern combined with diurnal heating and low-level convergence will likely lead to convective cloud development and a few scattered shallow showers developing over parts of England and Wales. However, given limited instability (up to 200 J/kg CAPE at best), weak shear in the cloud-bearing layers and restricted cloud depth (ELTs down to -10C) very little, if any, lightning is expected.
