PINAKI MAJUMDAR
Jamshedpur, March 31: A fresh phase of atmospheric instability is set to impact weather conditions across Jharkhand, with the India Meteorological Department (IMD) forecasting several days of cloud build-up, intermittent rainfall, and thunderstorm activity across large parts of the state.
March 31 is expected to see partly cloudy skies with isolated spells of light to moderate rain and thunderstorms, largely sparing the north-western districts.
Thunderstorm Activity to Intensify
Weather conditions are likely to intensify on April 1, with southern and adjoining central regions expected to experience thunderstorms accompanied by lightning and gusty winds of 30–40 kmph.
On April 2, similar conditions are likely over south-western and adjoining central areas. The forecast for April 3 and 4 indicates a gradual westward shift of the weather system, with western and central parts continuing to witness scattered rain and thundershowers. Southern regions may see relatively reduced activity towards the end of the period.

Synoptic Factors at Play
Meteorologists attribute the evolving weather pattern to a combination of factors. A trough extending from Bihar to Gangetic West Bengal across Jharkhand at about 1.5 km above mean sea level remains a key trigger.
In addition, an upper-air cyclonic circulation over north Odisha, along with a wind discontinuity extending from Odisha to Tamil Nadu, is enhancing moisture inflow and convective activity over the region.
Alert Issued for Several Districts
The Ranchi Meteorological Centre has issued a short-term alert for thundershowers in districts including Dhanbad, Giridih, Jamtara, Deoghar, Sahibganj, and Godda, warning of localised but potentially intense weather conditions.
Recent observations support the forecast, with Jamshedpur and nearby areas already witnessing thunderstorms, rainfall, and gusty winds. Isolated instances of hail have also been reported, highlighting the volatile nature of the system.
Experts note that such pre-monsoon activity is typical during this time of year, driven by rising temperatures and increased moisture. Residents have been advised to remain cautious during lightning and sudden wind events and to follow official safety advisories.
