“The winds blowing from this region are also not being warmed because of fog in Punjab and Haryana at a height of 300-500 metres, which is causing temperatures to fall there as well,” he added.

The IMD criteria for a cold day is that the minimum temperature should be 10 degrees Celsius or lower and the maximum temperature should be 4.5 degrees below normal. For severe cold day, the maximum temperature should be 6.5 degrees below normal.

Severe cold day is again forecast in some parts of the city on Friday, along with a cold wave, when the minimum temperature dips 4.5 degrees below the normal 8 degrees Celsius for this time of the year.
