CHENNAI: IMD has forecast light to moderate rainfall for the next two days that may keep the day temperatures in check. This, however, would increase the humidity to up to 85%, making it sweaty. Private forecasters said the intensity of rainfall may increase over interior areas and showers may last for three to four days.

Regional Weather Forecasting Centre director N Senthamarai Kannan said the rain activity would be due to a trough, an elongated area of relatively low pressure, extending from east Vidarbha to south Tamil Nadu. "There is a possibility of thunderstorm here and there in the city for the next two to three days. Day temperatures may be near normal," he said.

Mahesh Palawat, chief meteorologist, Skymet Weather, said the trough would lead to a change in wind direction to southeasterlies from southwest Bay of Bengal leading to a drop in temperatures but rise in humidity. "The city may get some isolated spells. Rain intensity may be more over interior Tamil Nadu. This trend may last for three to four days," he said.

Temperatures may be around maximum of 38°C-39°C and minimum of 29°C-30°C. The sky may remain partly cloudy. Relative humidity over coastal areas may be around 55%-85% till May 10. The average maximum temperature in the city in May is 37.3°C. There will always be two-degree difference between Nungambakkam and Meenambakkam stations due to their distance from the coast. May also brings an average of 43mm rainfall over an average 1.6 days.

On Monday, Nungambakkam and Meenambakkam recorded 35.9°C and 39.1°C. Humidity levels, which were at 75% and 67% at the two stations at 8.30am, shot up to 79% and 71%. This made the 'feel temperature' as high as 53°C over some parts of the city.
