Upper trough axis will be over the North Sea and Germany on Saturday, placing the British Isles on the rear side (and hence forward side of the approaching upper ridge). Residual cool air aloft, dry mid-levels and heating of moist low-level air, combined with orographic forcing and low-level convergence, will help generate a few scattered showers during the day, capable of a few sporadic lightning strikes and some hail in the most intense cells. There may also be a few funnel clouds.
