North-West and Central India could get bombarded with a ‘high-amplitude western disturbance’ and its offspring cyclonic circulation from Tuesday, unleashing heavy snowfall and rain in the hills and hail/thundershowers over the plains.
A series of ‘heavily endowed’ or ‘intense’ systems checking in to India are stark reminders, and represent a continuum, of the ‘deep freeze’ over the Arctic (poleward) regions of the US and Europe.
The parent disturbance pitched a tent over Iran and Afghanistan on Monday, but its offspring circulation would take birth farther downstream over North India as early as Tuesday, an India Met Department (IMD) update said.
And the latter would go on to create most weather over the hills and the plains of North-West and Central India before the parent can catch up, in what is a familiar pattern.
The circulation would pop over over West Rajasthan (unlike over South Pakistan as witnessed often) giving it added punch, and move to Punjab and Haryana by Friday.
Given the depth of the parent system, it would pipe in moisture from the Arabian Sea and trigger widespread rain/snow with isolated heavy to very heavy falls over Jammu & Kashmir, Himachal Pradesh and Uttrakhand on Wednesday and Thursday.
Heavy rain, hail
Widespread rainfall with isolated heavy falls are forecast for the northern parts of Punjab, Haryana, Chandigarh and West Uttar Pradesh on Thursday.
Thunderstorms/hailstorms may lash the hills as well as the plains in Haryana, Chandigarh, Delhi, West Uttar Pradesh, North Rajasthan, East Uttar Pradesh, North Madhya Pradesh, North Chhattisgarh, Jharkhand, Bihar and hills of Bengal and Sikkim.
Hardly would the ‘intense disturbance’ have signed out from the North and East than a successor chugs in afresh across the border and hits the western Himalayas from Sunday, setting off isolated to scattered rain/snow.
