"There is a possibility of development of thunder lightning towards evening," an India Meteorological Department officer told news agency IANS.
A private weather forecaster has also confirmed that wind speed and rain in Delhi today will not be of the high-intensity kind.
"There are chances of light winds and dust storm towards evening but they will not be of high intensity," said director of private forecaster Skymet, Mahesh Palawat.
The early morning temperature was fairly warm at 27 degree Celsius.
The temperature is likely going to rise starting Monday with the maximum temperature expected to go beyond 43 degree Celsius, the IMD said.
The System of Air Quality and Weather Forecasting and Research or SAFAR recorded "poor" air quality on Sunday morning. The Air Quality Index or AQI was 206 on a scale of zero to 500.
Saturday's maximum temperature was 41.4 degree Celsius and minimum was 26.4 degree Celsius.
On Wednesday, another thunderstorm had hit Delhi, with wind reaching up to 70 kmph. The authorities have asked people to stay indoors during dust storm.
Earlier this month, a severe dust storm across Uttar Pradesh and Rajasthan had killed over 100 people, uprooted houses and flattened trees.
Agra bore the brunt of the storm, with 43 people dying in the district. Bijnore reported three deaths and Saharanpur two, officials said.
Mango farmers in parts of Uttar Pradesh have also complained that their harvest has gone bad because of the dust storm. They would now have to sell the fruit at a much lower price.
