Weathermen at Skymet have cited a Western Disturbance over north Pakistan and adjoining Jammu & Kashmir, along with it an associated cyclonic circulation over Rajasthan and adjoining Punjab, as reasons for relatively less hot weather conditions in northwest plains. Northwesterly to westerly winds blowing in to the region are not hot enough to boost the maximum temperatures, which are currently below the normal at several places. Once the Western Disturbance moves away, day temperatures may rise sharply post the next 48 hours.
Day temperatures recorded below or near normal at most of the weather stations over Punjab, Haryana, Rajasthan, Delhi and West Uttar Pradesh, and forecast indicates that they may rise by up to two to three notches during the next two days.
The westerly winds continued to dominate Bihar and West Bengal where day temperatures were above normal by five to seven degrees at places like Patna, Bhagalpur, Bankura and Sri Niketan. According to the latest weather update by Skymet Meteorology Division in India, day temperatures are unlikely to drop hence heat wave will continue in this region.
Heat wave conditions also continued in Odisha on Sunday in spite of some rain in Chandibali, Cuttack and Dhenkanal under the influence of a trough of low that extends from sub-Himalayan West Bengal to Odisha. A weather alert has been issued by Skymet at 12:47 pm forecasting light to moderate rain and thundershowers likely at a few places over Balangir, Kalahandi, Kandhamal, Koraput, Nabarangpur and Rayagada districts of Odisha with strong winds averaging at 40 kmph while gusting at 70 kmph during the next 2 to 6 hours.
Northeast states would continue to draw moisture from southerly winds from the Bay of Bengal due to a cyclonic circulation over Assam. The weather system will continue to fetch moist winds that will usher in rain over Assam, Meghalaya, Arunachal Pradesh, Manipur, Tripura, Nagaland and Tripura. The region will continue to receive pre-monsoon rain in variable amounts during the week as well due to another cyclonic circulation in the Andaman Sea.
The weather in South India will continue to remain hot and humid as pre-monsoon rain remains subdued. Some places in Kerala, Karnataka, Andhra Pradesh and Tamil Nadu could witness some showers due to a trough of low extending from a cyclonic circulation over Vidarbha to Comorin area of Tamil Nadu across Telangana and south interior Karnataka and Kerala during the next two days.
