Two induced cyclonic circulations caused by the impact of a western disturbance passing through the northern parts of the country led to unseasonal showers in several districts of Jharkhand on Friday.

Weathermen said the circulations, coupled with wind convergence (easterly and westerly in the lower and middle levels of the atmosphere), resulted in adverse weather conditions.

The convergence of westerly and easterly winds resulted in heavy moisture incursion in the lower levels of the atmosphere, bringing rain. The condition also resulted in a rise in minimum temperatures,” explained Abhishek Anand, the deputy director of IMD's Ranchi Meteorological Centre.

He went on to say that weather conditions would improve from Saturday. "This would again result in a drop in night readings," he added.

Met statistics revealed that light rain occurred in several parts of the state since Thursday evening. Lohardaga recorded the highest rainfall of 8mm while Palamau headquarters Daltonganj recorded 5.5 mm rain.

Capital Ranchi, steel city Jamshedpur, Ramgarh, Khunti, Bokaro and several other places woke up to overcast skies. Ranchi witnessed rainfall in traces (which cannot be measured) while Jamshedpur and several other parts of Kolhan region experienced over 1mm rain.

Light showers were also reported from Koderma, Simdega and Giridih.

The adverse weather resulted in a rise in minimum readings. Ranchi recorded a minimum temperature of 12.5 degree Celsius, two notches above normal, while the minimum temperature in Jamshedpur rose to 11.3 degree Celsius, one point above normal.

Even as the minimum temperatures rose, maximum temperatures in several districts fell due to cloud cover.

A duty officer at IMD's Regional Meteorological Centre at Alipore in Calcutta said satellite pictures suggested improvement in weather conditions after the next 24 hours.

"Dry weather conditions are expected over Jharkhand from Saturday. But shallow to moderate fog would continue to prevail during the next few days in isolated pockets of the state," said the duty officer.

He said minimum readings were expected to fall 2-4 degree Celsius, signalling a return of the cold conditions in several districts after the next 24 hours.
