India weather forecast latest November 23 A colder winter than usual expected in northwest India

According to Skymet Weather, during the next 24 hours, scattered light to moderate rains is possible over Gangetic West Bengal, parts of north coast of Odisha, Northeastern states, isolated pockets of Chhattisgarh, Vidarbha, Tamil Nadu, and Kerala.

Andaman and Nicobar Islands may receive light to moderate showers with one or two heavy spells. Minimum temperatures of Central India where drop by around 2 degrees after 24 hours.

The Capital is likely to have a colder winter than usual this year, according to India Meteorological Department scientists who cited a Pacific Ocean weather phenomenon known as La Nina, which leads to a cascading impact on global weather in winter months.

During La Nina, temperatures in central Pacific Ocean drops below normal levels, triggering wind patterns can influence weather in far away regions. This has been linked to colder than usual winters in northwest India.

“Both maximum and minimum temperatures are likely to remain around 2-2.5°C below normal this entire season. Also, since winter is setting in early with temperatures already low, the minimum is likely to fall to 5-6°C as early as December 10. This usually happens after December 20,” said Kuldeep Srivastava, head of IMD’s regional weather forecasting centre (RWFC).

He added that day temperatures, or the maximum, will begin falling in early December.

Local factors too have contributed to making days colder. Delhi has had a cloudless streak, with only one Western Disturbance so far bringing in any moisture. “When there are no clouds, the ground cools faster and the minimum temperatures stay low,” he explained.

In the immediate days, Srivastava said that the minimum is expected to fall further to 7°C on Sunday before a Western Disturbance on November 23 briefly causes a slight increase. Once that passes, days and nights will become colder again.

“When global conditions like La Nina are prevailing, there is a tendency for regions under northwest India to get colder,” said VK Soni of IMD’s environment monitoring research centre.

Soni added that at present, the dip in mercury is accompanied by strong winds that helps in blowing away pollutants but after November 23, wind speed is likely to reduce and trigger a deterioration in air quality, Hindustan Times reported.

According to IMD, heavy rainfall is very likely to occure at isolated places over Tamilnadu, Puducherry & Karaikal and heavy rain/snow at isolated place over Jammu & Kashmir, Ladakh, Gilgit-Baltistan & Muzaffarabad.
