As we head into the second fortnight of February things will now slowly shift towards heat mode for Peninsular India. While mornings and nights may still remain pleasant or in some case fairly cool in the interior places days start getting hot heading towards the first phase of Summer. Typically its the west coast that sees temperatures rise first as many places along the coast in Kerala, Karnataka & Konkan start seeing temperatures cross 37ºC on a regular basis.
But the first batch of heat heavy weights will come interior Tamil Nadu around South TN & West Interior Districts. In the absence of sea breeze to give respite these places are among the first to make a race towards 40ºC along with parts of Rayalaseema. While February does not see temperatures heat up drastically time to time it does indeed show what to expect as we get to March. Weather models indicate temperatures to notch up by a degree or two over the interior areas of TN today.
In particular parts of Karur, Namakkal, Karur, Erode, Tiruppur, Madurai & Virudhunagar districts could see day time maximum temperatures stay 5 / 6ºC above average for this time of the year. Similarly most of Kerala is likely to see temperatures stay 4 / 5 degrees above normal during the weekend. Chennai could see day time max temperatures around 33ºC
