LUCKNOW, Jan. 16 -- The city recorded lowest minimum temperature of the season at 5.5 degrees Celsius on Thursday, due to strong Westerly Winds that pushed colder air into the region. While daytime conditions were stable due to sunshine, the morning and nights continue to be colder. The Indian Meteorological Department (IMD) has warned that while there is a possibility of drizzle/light rain in the north-western part of the state, the weather is likely to remain mainly dry in other agro-climatic zones of the state. Besides, due to the possibility of relative humidity remaining more than 90% from night to morning, there is a possibility of dense to very dense fog in the northern and central parts of the state. Clear sky during the day and dense fog in the morning are expected in the city with maximum and minimum temperature around 22 and 7 degrees Celsius, respectively. On Thursday, Lucknow recorded a maximum of 20.7 degrees Celsius, while the minimum was 5.5 degrees Celsius, about 1.6 degrees Celsius below the seasonal average. Humidity levels ranged from 94% in the morning to 42% by afternoon. Mohammad Danish, senior scientist at IMD Lucknow center, said, "The fall in temperature is due to strong cool Westerly Winds, which has led to the drop. The phenomenon is likely to continue for two days. Winds are expected to calm from Saturday onwards which would lead to an increase in temperature. Light rainfall is also possible in the West UP region on Sunday and Monday due to Western Disturbances." The cold spell was felt in other cities of the state as well with Hardoi recording the lowest minimum temperature during the night for the season at 3 degrees Celsius, while Bareilly recorded the lowest minimum temperature during the day for the season at 3.5 degrees Celsius....
