Distant rumbles just started in Romsey, presumably from the stuff coming up south east of the Isle of Wight, and turning very dark to the S/SE. As things stand it looks like we'll be too far west though.
Sky is like a who's-who of convective cloud types here in Romsey at the moment. Recent light shower of big splodgy drops from one of the more developed towers. Something's going to fire soon I feel!
