The Monsoon trough continues to run close to the Himalayan foothills almost across the western end to the eastern part, indicating the weaknesses in monsoon circulation. Meanwhile, a secondary branch of the aforementioned trough is seen dipping into Head Bay. This dip is associated with an upper air cyclonic circulation that is seen near Bangladesh and adjoining areas. Under its influence heavy rains are likely in the north eastern states along with parts of east India.
In the south, a trough at lower levels is seen running from Rayalaseema to Gulf of Mannar through Tamil Nadu. This may result in cloudy skies alongside some rains in parts of TN.
Chennai will see a much needed respite from heat in the days to come. Maximum temperature will stay close to 35 – 36 C, with a possibility of rains.
Coimbatore to see a cloudy day with day time maximum temperature settling closer to 32 C. Chances of light rains persists.
Madurai to stay hot with day time maximum temperature close to 37 – 38 C. Possibility of widespread showers is high.
