LUCKNOW: The city witnessed this winter’s first dense fog on Wednesday which along with cold winds ushered in the ‘chill effect’ into the atmosphere.
No relief is expected in the coming days as Met department officials have predicted cloudy skies and a few spells of light rainfall between Thursday and Sunday.
The dense fog led to a drop in visibility to 50 metres in the morning, which improved to 200 metres by afternoon.
As the thick blanket of fog did not allow ground heat to escape into the atmosphere during the night, the minimum temperature increased to 11.6 degrees Celsius, four units above normal.
However, the same sheet of fog did not allow sunshine during the day, resulting in a drop in maximum temperature to 18.5 degrees Celsius, 2.4 units below normal.
Cold winds added to the chill during the day.
State Met director JP Gupta said that a western disturbance over the Himalayas and a cyclonic circulation over Rajasthan will cause generally cloudy sky and a few spells of rainfall across the state from Thursday till Sunday.
In Lucknow, apart from light rainfall, moderate to dense fog might also occur, he added.
