The spell of Isolated Rains in South India is likely to continue under the influence of the trough extending from Vidarbha to Comorin Sea area. Yesterday saw isolated rains over Nilgiris region, parts of Krishnagiri district & places adjoining the Western Ghats region in Theni district. Temperatures stayed lower than the previous days over most parts of the state as well.
Isolated rains in South India are expected to continue though today we could possibly see lesser places get rains compared to the last few days with parts of Kerala & South Karnataka getting rains under the influence of the trough. Parts of Western Tamil Nadu is likely to see isolated rains particularly around the Coimbatore / Salem region. Similarly there is some chance of isolated rains in South Tamil Nadu as well around Madurai / Dindigul / Theni region. In the meanwhile after a long time Bay has seen a trough of low around South Andaman Sea which possibly will play a key role in the reversal of winds for the onset of Southwest Monsoon season.
Temperatures are likely to stay lower than last week under the influence of these unstable conditions in the atmosphere. Most parts of Tamil Nadu is likely to see temperatures stay below 40 degrees as coastal areas continue to get benefit from the early breeze from the East.
Chennai is likely to see day time max temperature of around 35 / 36 degrees with possibly sea breeze keeping the temperature under check early in the afternoon but the humidity is going to be fairly high making it a moderately uncomfortable day.
