On the forward side of an upper trough to the west of Biscay, a notably warm, moist airmass will cover southern Britain for a time on Saturday as a warm front lifts north, this relatively high WBPT airmass then shunted eastwards by a cold front this evening. Some elements of mid-level instability will be possible with some of this frontal precipitation, though in general near-saturated profiles and weak CAPE suggests the lightning risk is quite low in any one location.
