Dry Conditions to Persist over Tamil Nadu

As summer continues to firm up its grip over most parts of the Sub Continent including Tamil Nadu dry weather has been prevailing over South India with no immediate change seen in conditions.  As we get closer to mid March things will slowly fall in place for spells of summer thunderstorms to slowly start in the interiors due to changing wind patterns as atmosphere puts in place conditions for the Westerly regime over the Indian Sub Continent.

In what has been a welcome development the nights have been cooler than normal for the past few days over most parts of South India.  In particular North Tamil Nadu and adjoining parts of Rayalaseema & South Int. Karnataka have been seeing much cooler nights.  Puducherry recorded its coolest March night on Monday with 18.4°C which was repeated once again on Tuesday with 17.8°C.   Similar conditions are likely to persist for the next 2 /3 days with fairly cool mornings being estimated by the models.

Day time conditions are likely to be hot in the interior parts of Tamil Nadu with places in districts like Karur, Salem, Madurai & Virudhunagar seeing max temperatures around 36 / 37°C.  Coastal areas will be moderated by the Easterly breeze keeping temperatures to near normal with places like Chennai continuing to see max temperature around 32°C while delta areas will be even better around 30 /31°C
