Cold wave conditions were witnessed over parts of Haryana during the last 24 hours. Hisar recorded the minimum at 1.8 degree which is 7 degrees below normal. Day temperatures are also below normal by 4 to 5 degrees over many parts of Punjab, Haryana, Delhi, West Uttar Pradesh and Rajasthan.
This significant drop in the minimum temperatures can be attributed to the dry and cold northwesterly winds which have been travelling from the snow clad mountains of Western Himalayas.
A fresh Western Disturbance is approaching Western Himalayas due to which the impact of cold winds will diminish, and temperatures will start increasing leading to abatement of cold wave conditions.
An induced Cyclonic Circulation is expected to develop over Northwest Rajasthan and adjoining areas around February 8 or 9. Light scattered rain is possible over northern parts of Rajasthan on February 8 and over isolated pockets of Punjab, Haryana, Delhi and parts of West Uttar Pradesh on February 9.
These activities will not be moderate or heavy, therefore damage to crop is ruled out. Maximum temperatures are expected to drop by 2 to 3 degrees on February 9 and 10. On the other hand minimums will increase by 2 to 4 degrees.
