Answer:
Overnight thunderstorms lashed parts of Chennai and left some moisture hanging in the air (relative humidity) — to a maximum of 100 per cent at 5.30 am, according to the Chennai Met Office of the India Meteorological Department (IMD).
The temperature and dew point read at 26.8 degrees C each at that point. Three hours later, the temperature had gone up to 31.2 degrees C while the dew point had dipped to 28.1 deg C, and along with that, humidity to 85 per cent.
