After January7, however, the minimum temperature will again fall, bringing dense fog andcold wave conditions with it. “January 7 onward, the weather will startclearing up and cold winds from North will start blowing over Delhi leading todecrease in minimum temperatures. Due to increase in humidity levels and dropin temperatures, dense to very dense fog will once again make a comeback. Dropin temperatures might bring back cold wave conditions for the isolated pocketsof Delhi,” Mahesh Palawat, Director at private weather forecasting agencySkymet told IANS.
