The minimum temperatures across the northwestern plains started witnessing a brief rise from the last 2-3 days. Although weather remained same over most parts of Haryana, Punjab, Delhi, and Uttar Pradesh in the last 24 hours, the temperatures dropped again over many parts of Rajasthan. This marginal drop in the minimums over parts of Rajasthan was due to the change in the wind direction.
As per Skymet Weather, the ongoing Western Disturbance is over Jammu and Kashmir and its induced cyclonic circulation is over Punjab and adjoining areas have been responsible for the change. This weather system is restricting the fall of the temperatures over rest parts of the northwestern plains.
Skymet Weather further reiterates that whenever the minimum temperatures are 4 degrees or less and the sky is clear, chances of frost formation increases during the early morning hours.
Moreover, by tomorrow, the Western Disturbance is likely to move away eastwards. After the passage of this weather system, the cold northwesterly winds from the snow-clad Himalayas would once again start blowing over most parts of northwestern plains including Punjab, Haryana, West Rajasthan and West Madhya Pradesh. This would then lead to drop in minimum temperatures across the region.

Thus, people residing in Punjab, Haryana and North Rajasthan would witness a fall in the temperatures by 2-3 degrees, leading to the formation of ground frost at a few places between January 19 and 21. Along with these states, isolated parts West Uttar Pradesh may also witness frost formation.
Frost is a thin layer of ice gets that gets deposited on the standing crops, in turn suffocating the plants and thus, it may even result in damaging the crop.
