Lucknow experienced its coldest day of the season with a minimum temperature of 14.6 degrees Celsius, significantly lower than the previous season's low. While some eastern Uttar Pradesh cities saw temperatures above 20 degrees Celsius due to sunlight, western UP cities like Bareilly also recorded low maximum temperatures. Dense fog affected visibility across several UP cities, including Lucknow, Gorakhpur, and Agra, with weather officials attributing the conditions to atmospheric instability and fog layers trapping sunlight.
