While cold wave conditions prevailed in some parts over Odisha and in isolated pockets over Punjab, West Uttar Pradesh, East Rajasthan, Madhya Pradesh, Vidarbha and Telangana, cold day conditions were experienced in isolated pockets over Madhya Pradesh, the IMD said in a release on Wednesday. Under the influence of a Western Disturbance as a cyclonic circulation over north Pakistan & neighbourhood at lower tropospheric levels, isolated rainfall or snowfall is very likely over Jammu & Kashmir, Ladakh, Gilgit-Baltistan & Muzaffarabad and Himachal Pradesh on Thursday. Thereafter, two Western Disturbances in quick succession, the first from December 24 and second from December 26 are very likely to influence northwest India. "Under their influence, light isolated to scattered rainfall/snowfall is very likely over Western Himalayan region on December 24 and 25 and light isolated rainfall is expected over northern parts of Punjab & Haryana during same period," the IMD said, adding, "Thereafter, under the influence of intense fresh Western Disturbance from December 26, precipitation activity is very likely to increase further over northwest India with light/moderate scattered to widespread rainfall/snowfall over Western Himalayan region during December 26 to 29 with possibility of isolated heavy falls over Kashmir region and Himachal Pradesh on December 27." Light/moderate isolated to scattered rainfall is also likely over Punjab, Haryana, Chandigarh & Delhi, Uttar Pradesh and Rajasthan during December 26 to 29 and over Madhya Pradesh, Chhattisgarh, Bihar and Jharkhand during December 27 to 29.
