At 3.9 degree Celsius, Delhi records season's lowest minimum temperature

In Delhi, the temperature dipped to 3.3 degree Celsius and 3.4 degree Celsius at Lodhi Road and Ayanagar, respectively, the India Meteorological Department (IMD) informed.

Yesterday, the minimum temperature had dropped to as low as 2.7 degree Celsius at Jafarpur.

However, the maximum temperature rose from 15.2 degree Celsius on Thursday to 19.8 degree Celsius on Friday.

Kuldeep Srivastava, head of IMD's regional weather forecasting center, said, "The minimum temperature dipped due to cold winds coming from the snow-capped hilly region. Cold wave conditions are forecast for Saturday at a few places during morning hours."

Meanwhile, "maximum temperature rose because fog conditions over Punjab and Haryana reduced, which warmed up cold winds blowing from the western Himalayan region," he added.

The dipping temperatures have been attributed to widespread snowfall in the Western Himalayas, and frosty winds blowing toward the plains.

Notably, a "cold day" is declared when the minimum temperature is less than 10 degree Celsius and the maximum is at least 4.4 degree Celsius below normal.

Further, a "severe" cold day is when the maximum temperature is at least 6.5 degrees below normal.

However, Delhi is likely to receive some respite from the extreme cold for four days from Sunday.

"The minimum temperature may hover around 7 degree Celsius in the first four days of the next week, while the maximum is likely to remain around 23 degree Celsius. Moderate fog is predicted from December 22 to 24," an official said.
