Rain with hail was caused by a rare, strong Western Disturbance, which at present lies over east Jammu & Kashmir. Western Disturbances (low pressure area formed in the Mediterranean Sea and the Atlantic Ocean) are common during the winter in India and January usually receives such weather systems. But, the uniqueness about the present weather system is that it has breached its southern limit this time around and reached up to Rajasthan. The weather system is usually confined to north Haryana and Delhi.
A cyclonic circulation associated with the weather system was hovering over Rajasthan which in tandem with the low pressure area (Western Disturbance) has brought a period of heavy rain and hail storm that hit lives in northern India. Rain in Delhi and other places in the north will reduce, as the weather system will make an exit from Jammu & Kashmir.
