Popups in North TN coast, still some moisture left and as depicted in the previous synoptic chart as it nears the land, it converges.
Expecting sharp spell not only at Chennai at isolated places but also as time goes on, we can expect sharp spells right from Ramanathapuram till Chennai. It`s not such a strong bands of clouds as seen in the morning. So it will not be widespread.
