Heavy rain may cover south Tamil Nadu on May 11.

Thunderstorms, with gusty winds reaching a speed of up to 40 km per hour, may keep the temperature under control till the weekend. However, there is a chance for temperature to climb up to 41 degrees Celsius in a few places in interior Tamil Nadu and the day temperature may remain at 38-39 degrees Celsius in other parts of the State. The coastal region may experience a maximum temperature of 35-37 degrees Celsius till the weekend.

On Wednesday, Chennai received its first summer rain. However, it was a mild and short spell at Nungambakkam as well as Meenambakkam, with less than 1 mm recorded.
