In just two days, minimum temperatures in Lucknow have slipped from 8.7 degrees Celsius to 5.1 degrees Celsius. Day temperatures, however, continue to hover around 24.4 degrees Celsius. The sun shines bright through the day, keeping day temperatures high.
Met department officials say sunny days will soon be gone, as fog envelops many parts of the state. Foggy days are already being experienced in Lucknow, Kanpur, Sitapur, Lakhimpur Kheri and Ghaziabad.
Train schedules have been hit by fog, and flights too are likely to be hit as fog gets even more dense in the days to come.
