Southwest Monsoon Update: Southwest Monsoon continues to be active over Peninsular India and in particular over West Coast with coastal Karnataka & Kerala getting rains at many places.
Most parts of India is going through practically dry weather.The situation is expected to continue for a couple of more days until a possible low evolves over Central / North Bay which could bring back the monsoon dynamics to Central & East India. 
In the meanwhile a lower level off shore trough over West Coast is aiding the cross equatorial moisture flow into Peninsular India bringing high rain possibilities to Coastal Karnataka and Kerala. Central Kerala & South Karnataka could see another good rainy day. Parts of Telengana & North Karnataka may benefit from wind discontinuity at mid levels which could give heavy spells of rains in one or two places.
Tamil Nadu Weather Update: With the monsoon active over West Coast and some bit of moisture travelling across the Peninsula most parts of Tamil Nadu could see cloudy skies with temperatures around 34° – 35°C in the plains. Isolated rains may be possible in a few areas around Madurai, in South TN and possibly around Trichy in the Delta region. One or two thunderstorms may pop up in the North TN region along the areas adjoining the Rayalseema region near Chittoor / Tirupati.
Chennai Weather Update: Another pleasant day on the cards with cloudy skies and temperature around 33°C. One or two areas could get isolated spells of showers late in the evening.
