After a short break, thunderstorms are set to return over North Tamil Nadu including Chennai City.
Strengthening of convergence, increase in moisture over PBL layer will bring back thunderstorms over North Tamil Nadu from 30th of May. Initially the rain will be concentrated over interior districts of North Tamil Nadu, and will gradually spread over coastal areas too from 31st may.
As there is no proper synoptic support, these rains will be completely convective based and sea breeze induced one. So it won’t be widespread. Scattered rains likely.
Chennai city will see party cloudy skies with scattered rains towards late afternoon/evening/night. Thunderstorms will continue until June 6/7th .
