A cyclonic circulation over the Bay of Bengal caught Jharkhand by a light shower surprise on Wednesday.
The maverick weather pushed up minimum temperatures, bringing winter to a warm phase that is expected to last for at least another 48 hours.
Weathermen said the state was in the grip of twin systems — a cyclonic circulation near the Andaman Sea and a low-pressure trough extending from Chhattisgarh to Bangladesh via Jharkhand.
“The circulation formed over the Bay on Tuesday evening and resulted in heavy moisture incursion into the lower strata of the atmosphere. This resulted in light rain today. The condition also resulted in an abrupt rise in minimum readings,” explained A.K. Sen, the director of Patna Meteorological Office.
Morning showed the day in Ranchi, Jamshedpur and Daltonganj on Wednesday as local residents woke up to fog and overcast sky. Later, light showers were experienced in a few pockets of the capital and the steel city. While Ranchi recorded 0.3mm, Jamshedpur received 0.5 mm.
Drizzle was also reported in districts like West Singhbhum, Seraikela-Kharsawan, Jamtara, Dumka and others in the eastern part of the state.
Minimum temperatures sprinted up at most places.
In Jamshedpur and its adjoining areas, the readings shot up by four degrees. The steel city weather office recorded 14.3°C against 10.8°C on Tuesday. Wednesday’s minimum was two notches above the average normal. Ranchi also witnessed a rise by two degrees, recording 13.5°C against 11.7°C some 24 hours ago.
In Daltonganj, the minimum went up by three degrees in 24 hours. The local observatory recorded 14.5°C compared to 11.4°C on Tuesday.
Maximum temperatures, on the other hand, took a dip.
Ranchi was 23.4°C on Wednesday, down from 26.5°C on Tuesday, while Jamshedpur recorded 23.7°C against 26.6°C. In Daltonganj, the reading fell by three notches to 24.2°C.
Weathermen at Regional Meteorological Centre in Calcutta said the twin systems would prevail for 48 hours.
“There has been a change in the wind pattern. The easterly is dominating over Jharkhand, Bengal and Odisha. The sky will remain cloudy for the next two days. Light rain at a few places are likely,” said director G.C. Debnath.
In its long-range forecast, the Patna Met office said the weather would improve only after 48 hours. “The weekend will bring back the chill,” said a weather analyst.
