Snowfall and light rains are likely over the western Himalayas, including Jammu and Kashmir, Himachal Pradesh and the upper reaches of Uttarakhand between 18 and 20 November, under the influence of a western disturbance that brought widespread rain and snow to the region. on Sunday.

“We are seeing a substantial improvement in air quality in the Northwest region due to the favorable weather conditions that have helped disperse the Diwali pollution,” said Vijay Soni, a scientist in IMD’s air quality division.
The impact of the WD has begun to diminish. It is currently found as a cyclonic circulation over northern Pakistan and its surroundings.
“There was snowfall in many places over Jammu and Kashmir, Himachal Pradesh and over Uttarakhand on Sunday. Rain and showers occurred in Punjab, Haryana, Chandigarh, Delhi and Uttar Pradesh and in some places in northern Rajasthan. Today the winds are from the east but will change to the northwest starting Tuesday. Then cold winds will blow from the western Himalayas, where the snow has just occurred. We expect the minimum temperature to drop below 10 degrees C in the coming days, ”said Kuldeep Shrivastava, director of the regional weather forecast center. The change of wind direction towards the northwest will cause a drop in the minimum temperature on Wednesday temporarily. The minimum temperature is likely to rise again as a new, weak western disturbance is likely to hit the region on November 18.
“A weak WD is likely to affect the higher areas of Jammu and Kashmir and Himachal Pradesh again on 18 November. Therefore, the minimum temperature will drop on November 16 and 17, but will rise again on November 18 before falling substantially after that. The current active western disturbance coincided with Diwali, which brought great relief from air pollution to all of Northwest India, ”added RK Jenamani, Senior Scientist at the National Weather Forecast Center.
