A fresh Western Disturbance is approaching North India, which will give light to moderate rain over most parts of Jammu and Kashmir and some parts of Himachal Pradesh.
An induced cyclonic circulation can also be seen over north Rajasthan, which is expected to trigger dust storms and thunderstorms over parts of Rajasthan, Haryana, Punjab and Delhi NCR.
In wake of these systems, wind pattern has changed from from hot northwesterly winds to humid southwesterly winds, which has led to drop in temperatures across Northwest India.
A cyclonic circulation is still prevailing over Arunachal Pradesh and will continue to give fairly widespread rain over entire Northeast India.
The trough from the cyclonic circulation over East India will extend up to Andhra Pradesh along the coastline. We can expect some thundershower activity along the well-marked trough line that will include Telangana and Andhra Pradesh.
Pre-monsoon activity over South India has picked up once again. A trough extending from interior parts of Karnataka up to Tamil Nadu is giving rain over the region. We can expect fairly widespread light to moderate rain over Tamil Nadu, Kerala, Karnataka and adjoining parts of Andhra Pradesh tomorrow.
Coming to temperatures, severe heat wave conditions have abated from several parts of the country, however, day temperatures are still settling above the 40° mark. Worst affected states of Telangana and Andhra Pradesh have also received some respite.
Heat wave is now only confined to interiors of Odisha, Chhattisgarh, Jharkhand, East Madhya Pradesh and Vidharbha.
