Patna: Heavy rainfall accompanied by thunderstorms and lightning swept across Patna and several other districts on Sunday, as dense cloud cover plunged parts of the state into near-darkness in the middle of the afternoon.
Residents reported that skies turned unusually dark shortly after 4pm, creating conditions resembling evening before intense rain, thunder and lightning followed.
Storm Resembles ‘Kal Baisakhi’ Pattern
Meteorologists said the sudden weather shift bears resemblance to Kal Baisakhi — a seasonal storm typically seen in April and May across eastern India, marked by strong winds, thunderstorms and heavy rain.
Such systems form due to the collision of warm and cold air masses and are often associated with sudden, intense weather activity that can pose risks to life and property.
Factors Driving The Weather Shift
According to weather officials, moisture-laden winds from the Bay of Bengal are increasing atmospheric humidity across Bihar.
At the same time, the influence of western disturbances is maintaining instability in the atmosphere, creating favourable conditions for cloud formation, thunderstorms and gusty winds.
Localised interactions between heat and humidity are further accelerating rapid cloud build-up, leading to sudden downpours.
Unsettled Weather To Continue
The meteorological department said the current spell of unstable weather is likely to persist until May 7, with intermittent storms and rainfall expected across several parts of the state.
Officials added that the ongoing conditions are also expected to bring down maximum temperatures by 2C to 4C, offering temporary relief from the early summer heat.
