Chances of light rain tomorrow in Delhi: Meteorological Department

NEW DELHI: The longest spell of fog in Delhi this season started to grip the city from 8.30pm on Sunday. From 1am onwards, it became denser and remained so till 11.40am.
Thereafter, there was some improvement till 4.30pm, when visibility extended to 1,000 metres. However, fog returned soon enough and visibility had dropped to 600m by 5.30pm and got progressively worse.
The minimum visibility at both Palam and Safdarjung was below 25m during the morning hours, against 50m a day earlier. Earlier on December 27, the city had seen an 18-hour long fog, though visibility then had kept improving unlike on Monday which it dropped again after a few hours of respite.
"The winds had been calm since 5pm on Sunday. There is an ongoing western disturbance which has caused some snowfall in the Himalayan region. This induced high moisture in the city. There was already clouding since Saturday night. These factors lead to a deepening of the fog across Delhi-NCR," said R K Jenamani, senior IMD weather scientist. He added that the situation may improve from Tuesday night, with the intensity of fog expected to be dense on Tuesday and hover between moderate and dense on Wednesday.
"There are chances of the city receiving easterly wind from late Tuesday night with speeds up to 10-20kmph, which will continue till Friday morning. So, the fog situation may improve from January 11 to 13. The cold wave will also improve in the same period," Jenamani said.
He added that the city may get light rain in the period between Wednesday night and early Thursday morning.
Meanwhile, Delhi continued to reel under a cold wave on Monday, along with isolated cold-day situations in some areas. The minimum temperature at the base station of Safdarjung was recorded at 3.8 degrees Celsius, three notches below normal, against 1.9 degrees C a day earlier. The maximum temperature was 18.6 degree Celsius, a notch below normal.
