One or two isolated showers may develop on Wednesday late afternoon / early evening over East Anglia in response to diurnal heating and low-level convergence. CAPE is somewhat limited, with hints of a warm nose at approximately 700mb which may inhibit deep convection. Forecast profiles do exhibit curved hodographs in the low-levels. Most areas will remain dry and lightning-free.
Late on Wednesday night (early hours of Thursday) there are subtle hints of some mid-level instability release occurring, mainly over the English Channel and later into southern England, with scope for a few high-based showers. A few sporadic lightning strikes might be possible from this, if depth of convection is sufficient, and also in SW Ireland associated with approaching front.
