This is the lowest minimum temperature for January after 2006. The lowest ever minimum temperature over Delhi has been recorded as 0.2°C on 8th January 2006.

As per IMD Cold wave to severe cold wave condition is prevailing over Delhi since 28th December 2020. It has intensified since 29th December with Safdarjung recording 3.6°C, 3.5°C, and 3.3°C respectively on 29th, 30th, and 31st December 2020. During 31st December-1st January night, clear skies with falling cal radiation cooling led to a fall of minimum temperature by 1 to 2°C and hence leading to the lowest temperature of the season as 1.1°C.

A fresh active Western Disturbance is likely to affect Western Himalayan Region & adjoining plains from 03 January onwards. Due to interaction between the above Western Disturbance and lower level easterlies from the Bay of Bengal, scattered to fairly widespread rainfall accompanied with thunderstorm/hailstorm at isolated places likely over Delhi during 3-5 with maximum intensity on 04 and 05 January 2021.

IMD has predicted that a Western Disturbance as a cyclonic circulation lies over Afghanistan & neighborhood at middle and upper tropospheric levels. It is likely to move slightly eastwards to central Pakistan and neighborhood during the next 48 hours and remain practically stationary there during subsequent 3-4 days.

An induced cyclonic circulation lies over southwest Rajasthan & neighborhood in lower tropospheric levels and is likely to persist over the same area during the next 3-4 days. The confluence of southwesterly in association with the above Western Disturbance and lower level southeasterlies is very likely over plains of northwest and adjoining areas of central India during 2-5 January 2021.

Under the influence of the above systems, light/moderate fairly widespread rainfall/snowfall over the Western Himalayan region during 4-6 January with its peak intensity on 4 and 5 is very likely with the possibility of heavy rain/snow over Jammu Division & Kashmir Valley.

Scattered to fairly widespread rainfall accompanied by thunderstorm/hailstorm at isolated places very likely over Punjab, Haryana, Chandigarh and Delhi, north Rajasthan, West Uttar Pradesh and northwest Madhya Pradesh during 3-5 with maximum intensity on 03rd and 04th January. Isolated heavy rainfall also likely over Punjab on 04th January 2021.
