Several parts of Jharkhand, including Jamshedpur and Ranchi, witnessed thunderstorm, lightning and rain due to the impact of a cyclonic circulation and a low-pressure trough on Sunday.

Satellite pictures indicated a cyclonic circulation over eastern Uttar Pradesh and a trough over neighbouring Bihar extending upto 0.9 km above mean sea level.

Based on satellite pictures and radar inputs, Ranchi Meteorological Centre had issued frequent nowcasts (short-term forecast) through Sunday indicating moderate thunderstorm and showers in central and southern Jharkhand.

Chaibasa in West Singhbhum, Gumla, Simdega and Khunti were among the places that experienced thunderstorms and lightning. Elsewhere, say, in Bokaro and Ramgarh, the sky was partly cloudy and there were light showers accompanied by gusty winds.

Ghatshila in East Singhbhum experienced 2mm rain while the local weather office in Jamshedpur recorded 1mm rain.

The steel city, along with several other places in southern and central Jharkhand, witnessed sudden strong winds on Sunday afternoon which blew at a speed of 30kmph.

Met data revealed Ranchi recorded 2mm rain in past 24 hours, while Chas in Bokaro district recorded around 9mm rain.

Chandil in Seraikela- Kharsawan district and Khunti experienced around 4mm rain.

According to Ranchi Met office deputy director Abhishek Anand, light rain or thunderstorms are expected in isolated pockets, especially in central, north-east and southern Jharkhand, in another 24 hours due to the impact of the cyclonic circulation.

He also hinted at gradual rise in maximum readings after the next 24 hours.

A senior weather analyst at Patna Met Centre said the cyclonic circulation over Uttar Pradesh was resulting in heavy moisture incursion into the atmosphere from Bay of Bengal which resulted in rise in humidity level in most parts of the state.
