This winter, it's the plains, reporting sub-zero temperatures and severe fog.
Northern plains report severe temperatures, in three cities, with Hisar (Haryana) recording -1.2°C and both Churu(Rajasthan) and Bathinda (Punjab) record -0.2°C. While the mercury in Delhi drops to 1.1°C at Safdarjung, making it the season's lowest.
As rare as it seems, many more regions experienced a drop in temperature. Faridkot (Punjab) and Narnaul (Haryana), recorded a least of 0.2°C each. Lucknow airport also saw a drop of 0.5°C.
Cold northwesterly winds are blowing over Delhi NCR from Jammu and Kashmir and Himachal Pradesh and, along with the uplifting fog cover over Punjab and Haryana, makes it further decrease the temperature. Yet, lower than normal weather was expected, due to this being the La Nina year - globally when temperatures over the Pacific are low. These conditions make winters harsh, as reported by the Indian Meteorological Department.
A fresh wave of western disturbance is likely to affect the Western Himalayan region and the neighboring plains from January 3 onwards. It can cause light to moderate snowfall over the western Himalayan region between January 3 and 6. Cold wave situation is expected in few regions of Punjab, Haryana, Chandigarh, Delhi, Uttar Pradesh, and West Madhya Pradesh during the next two days and over Himachal Pradesh during the next 24 hours.
