Delhi has been experiencing dry and hot weather conditions since April 18. In fact, on April 30, Delhi witnessed highest temperatures of the season. While the Palam observatory equaled the all-time record of 45.3°C which was established in the year 1970, Safdarjung observatory also recorded highest temperature since, April 30 in 2010.
During the last two days, temperatures have decreased to some extent as easterly winds have commenced over Delhi and NCR. At present, A Cyclonic Circulation is present south of Delhi over Northeast Rajasthan and adjoining areas.
Now, due to the influence of Cyclone Fani, easterly winds from Bay of Bengal are expected over Northern Plains including Delhi and NCR up to the height of 10,000 ft.
Whenever, temperatures are high, and humidity increases it leads to instability in the atmosphere. Due to this, thunderclouds develop which are capable of giving dust storm and isolated light thundershower.
We already witnessed isolated dust storm activity over Delhi and NCR yesterday evening. Apart from this, on and off pre-Monsoon activities are expected to occur on May 3 and 4 over Delhi and NCR.
These weather activities will reduce the maximum temperatures over Delhi and NCR. Minimums may also fall due to the dust storm activities.
By May 5, the humid easterly winds will be replaced by dry and hot winds from Northwest leading to clearance of weather, clear sky and bright sunshine. The temperatures will once again increase due to these winds.
