Colder nights likely for Chennai and suburbs from December 12
Meanwhile, the Regional Meteorological Centre (RMC) has forecast light to moderate rain in parts of Tamil Nadu, Puducherry and Karaikal on December 10 and 11, caused by a trough (relatively low atmospheric pressure region) over the southwest Bay of Bengal.
CHENNAI: A high-pressure system from December 12 will bring cold, dry winds, creating mini cold wave-like conditions across central India. The chill will also reach north Tamil Nadu, including Kancheepuram, Tiruvallur, Chengalpattu and Chennai, said Pradeep John, who runs the popular Tamil Nadu Weatherman handle.
As a result, Bengaluru and Hosur may see minimum temperatures of 10-12°C at night, while Ooty and Kodaikanal could drop below 5°C. Vellore, Tirupattur, Salem, Erode, Coimbatore and Dharmapuri are also likely to experience cold and dry weather, the weather blogger forecast.
He added that, in contrast, west coast cities will be unusually hot for December, even as much of the region turns cooler.
