New Delhi recorded a minimum temperature of 6.5 degrees Celsius, two degrees below normal on Sunday. The temperature rose slightly due to cloudiness caused by a western disturbance affecting the Jammu & Kashmir region. The impact of the westerlies will continue for another two days. The minimum temperature is expected to dip from Wednesday and may drop to 6 degrees Celsius, with a possibility of reaching 5 degrees Celsius on December 21 and 22.
