KOLKATA: The city will remain cloudy and may receive a light drizzle on Thursday or Friday under the impact of a high-pressure zone that is now sailing across south Bengal towards Bay of Bengal. Once the system passes away by Saturday, the mercury may drop to 17°C-18°C, said the Met office.
"The high-pressure system has been pulling in moisture that has led to clouds. This may eventually lead to light rain in the city," said regional meteorological centre (RMC) director G K Das. He added the system has triggered thunderstorms in Midnapore on Wednesday. "But the high pressure is moving away towards the sea. It should cease to have any impact by Saturday. Once that happens, the wind direction will change, leading to a temperature drop," added Das.
