Westerly entourage preparing to exit northwest

The eastward-bound western disturbance preparing to exit Jammu and Kashmir has dragged an offspring cyclonic circulation from south Rajasthan to southwest Uttar Pradesh overnight on Saturday morning.

The latter has also brought associated footprint of varyingly violent weather associated with it to bear over the eastern parts of the plains of north and northwest India.

An India Meteorological Department (IMD) update on Saturday morning said that the parent western disturbance parked over Jammu and Kashmir on the previous (Friday) evening is now moving eastwards.

The system would still be able to influence weather over western Himalayan region and the adjoining plains of northwest India until Sunday morning.

A weather warning issued by the IMD said that isolated heavy rain or snow would occur over Jammu and Kashmir and Himachal Pradesh until Sunday morning. Isolated hailstorms or thunder squalls may occur over the Jammu division and increasingly over Uttar Pradesh and Bihar to the east where the cyclonic circulation is perched.

A weather update during the day and until Friday evening said that fairly widespread rain or snowfall was reported from Jammu and Kashmir and Himachal Pradesh and isolated over Uttarakhand. Scattered rainfall occurred over sub-Himalayan West Bengal and Sikkim while it was isolated over Haryana, Delhi, Uttar Pradesh, Bihar, east Madhya Pradesh and Chhattisgarh.

Satellite imagery early on Saturday morning showed the presence of convective (rain-bearing) clouds over parts of Jammu and Kashmir and in the south over the Comorin area (peninsular tip).

Minimum temperatures would fall by 2 to 3 deg Celsius over northwest India and the maximum temperatures would rise by the same amount over plains of northwest and adjoining central India during next two to three days. This is because of the clear skies emerging after the western disturbance exits the northwest region of the country.
