After a fairly long break there is some chance for rains in South TN starting from tonight. The last couple of weeks have seen mostly scorching conditions across the state with the interiors blazing under early summer like conditions. Madurai, Palayamkottai, Trichy all set their hottest March records in this spell of extreme heat.
The last couple of days though Easterlies have once again established itself bringing down the temperatures in the coastal areas with most places recording normal or in some cases below normal temperatures as well providing a huge relief from the intense heat. Interior areas continued to be fairly hot though but marginally better off than the previous week. Yesterday was the third day when no station in Tamil Nadu recorded day time high temperature of above 40 degrees.
Thanks to the Trough of Low in Southwest Bay we are likely to see rains in South TN from tonight as Easterly Wave moves closer to South Tamil Nadu. In particular the districts of Kanyakumari, Tirunelveli & Thoothukudi are likely to see heavy rains at one or two places with the places around Nagerkoil and the Western Ghats adjoining Tirunelveli likely to see spells of heavy rains. Along with these places districts of Virudhunagar & Ramanathapuram could see isolated spells of rains with places like Aruppukottai possibly benefiting from these rains.
Rest of Tamil Nadu is most likely going to stay dry with partially cloudy conditions in the coastal areas south of Nagapattinam. These cloudy conditions could keep the temperature under check in the coastal areas while interior places is likely to see hot conditions similar to the last few days with temperatures in the Western TN staying around 37 /38 degrees.
