A dual cold front will be slowly clearing southeastwards across England and Wales on Sunday morning, within a strongly-sheared environment. The frontal boundaries are likely to exhibit marked temperature and wind speed gradients and wind veer. One or two well-pronounced bands of line convection are expected to develop, producing a narrow zone of very heavy rain and perhaps some gusty winds. In general the shallow nature of convection coupled with saturated profiles and weak instability suggests the risk of lightning is fairly low. Nonetheless, should line convection fracture or evolve into an LEWP, perhaps with interaction with local topography, an isolated tornado may be possible.
