Delhi witnessed the coldest day of the season as temperature dropped three degrees below the normal average night temperature of 7.6 degrees Celsius on January 11.
Till now Delhi has seen a relatively mild winter but temperature dropped to 4 degrees Celsius in the early hours of Wednesday.
According to the Regional Weather Forecasting Centre (RWFC), temperature may not rise over 16 degrees Celsius during the course of the day.
Even though the temperatures dropped to the lowest levels, the capital had a fog free day on Wednesday, whereas dense fog may prevail in Gurgaon for next few days.
According to officials dense fog may prevail till January-end. The westerly and north westerly winds are responsible for the clearing of fog in Delhi and the drop in temperatures in NCR.
An RWFC official said, ‚ÄúWesterly and north westerly winds are colder because they blow over places like Jammu and Kashmir and Himachal Pradesh before reaching Delhi. As there have been reports of snowfall in these areas, wind gets colder. This helps bring down the temperature in the national capital.‚ÄĚ
¬†Moisture gets dried up when it is windy. The wind also does not allow water droplets to condense in the air; it blows it away,‚ÄĚ explained a weather expert from the Airport, who claimed that the IGI airport experienced an unseasonally fog free day on Tuesday, and are hopeful that this bout of good weather will continue for another two to three days.
