With the last few nights relatively cool its time to enjoy the last phase of winter in Tamil Nadu before the seasonal heat slowly starts to show up its face in the region. Most places of the state has been seeing night time minimum temperatures that are a degree or two below normal.
Similar cooler nights are expected to continue for another couple of nights or so with many of the interior places seeing minimum temperatures drop below 20°C while coastal places like Chennai see early morning temperatures settle at around a comfortable 20 / 21°C. With dry conditions likely to prevail until weekend at least this pattern of weather will continue until Sunday
After Sunday the models indicate nights to become warmer across most parts of Tamil Nadu. This phase of warmer nights will eventually lead to the seasonal shift towards spring / early summer in the interiors and southern parts of Tamil Nadu during the first fortnight of March
