Yesterday, many parts of Delhi and its adjoining areas such as Noida, Gurugram, Ghaziabad and Faridabad experienced rain and thundershower activities. In fact, one or two places even reported intense short spells of rain and thundershowers.
Both Palam and Safdarjung observatories recorded 2mm of rainfall over Delhi and NCR area.
These rains were the results of an active Western Disturbance over Jammu and Kashmir. This system had induced a Cyclonic Circulation over West Rajasthan and adjoining areas. A Trough from this system was also extending up till West Uttar Pradesh across Delhi.
According to Skymet Weather, now as the Trough has slightly moved northwards, we do not expect much rain activity over Delhi and NCR area today. However, other parts of Northwest India such as Punjab, Haryana and Northwest Uttar Pradesh will continue experiencing these rains even today.
By tomorrow, the induced Cyclonic Circulation will move over Punjab and Haryana. Moreover, the Trough is also expected to shift southwards. In wake of this movement, many parts of Delhi and NCR area will receive light to moderate rain and thundershower activities. These on and off rains will continue lashing the region until February 22. There are also bright chances of hailstorm at one or two places, but the intensity will remain on the lower side.
Further, by February 23, the present Western Disturbance will move away in east directions. The Trough will also shift over East Uttar Pradesh and Bihar. Thus, rains will start vacating the parts of Northwest India including Punjab, Haryana, Delhi and Northwest Uttar Pradesh and weather will start clearing up.
Moreover, due to the eastward movement of the Western Disturbance, the icy cold winds from Western Himalayas will once again start blowing over Delhi and NCR area, thereby leading to a drop in both day and night temperatures. However, the drop will not be a steep one as compared to the last week. However, in spite of bright sunshine, the winter chill would be felt during day hours.
