Yesterday saw the IMD observatory at Chennai Meenambakkam record its lowest temperature during the month of March in nearly 3 decades dipping up to 18.6°C. The last few days have seen most places of North Tamil Nadu record much lower than normal minimum temperatures with a nip in the air during mornings. Places like Tiruttani went lower than 15°C which does not happen often during the month of March.
The day time conditions are likely to remain near normal across most parts of the state with possibly places in South Tamil Nadu seeing marginally warmer than normal conditions during the afternoon. Unlike last weekend when Salem recorded the first 100°F of 2018 on Saturday the next few days are unlikely to see any abnormal increase in day time conditions with the strengthening Easterlies under the influence of developing synoptic conditions will keep temperatures under check.
The cool mornings of the past few days over Chennai & Suburbs are going to be a thing of past with the early morning temperatures at both the IMD observatories in Chennai showing an appreciable increase compared to yesterday and possibly the warmest morning since the turn of March. Similar trend is expected to continue as a gradual increase in night time temperatures are expected to prevail over most parts of Tamil Nadu including Chennai.
