Fresh westerly system to enter north-west by weekend

India Meteorological Department (IMD) too has joined the lookout for a fresh western disturbance crossing in from the northwest border from the weekend.

International models are of the view that the system would progressively cause snow and precipitation over the western Himalayas with some spill-over impact indicated for the adjoining plains.


Jammu and Kashmir, Uttarakhand, Himachal Pradesh, parts of north Rajasthan, Punjab and Haryana are expected to get directly impacted thus during the week ending February 8, according to the precipitation forecast of the US National Centres for Environmental Prediction (NCEP).

The showery weather may extend further in area during the following week (February 9 to 17) even as an easterly wave has been shown to impact the extreme south peninsula (south Kerala and Tamil Nadu).

Meanwhile, the NCEP ensemble forecast for 15 days has indicated that the three days starting February 7 would witness most of the weather over north and northwest India.

A second episode of showery weather has been indicated on February 12 and 13, tapering off to the east over the next two days, according to the ensemble forecast.

An isolated incidence of enhanced weather activity is indicated for east India – around Chhattisgarh, Vidarbha and east Madhya Pradesh during the period.

There is already a forecast for increasing cloud cover over northwest and adjoining central India from mid-February. This would mean spotty shower episodes and elevated night temperatures.


During the 24 hours ending Monday morning, minimum temperatures were below normal by 2 to 3 deg Celsius over many parts of east and peninsular India and parts of northeast India.

They were above normal over parts of Gujarat, central and northwest India while being near normal over remaining parts of the country.

Day temperatures were above normal over Himachal Pradesh and parts of Assam, Arunachal Pradesh, Rajasthan, Madhya Pradesh and Uttar Pradesh.

Northwesterly winds have been prevailing over Indo-Gangetic plains in lower levels during this period. They are forecast to strengthen further from Wednesday ahead of the arrival of the fresh western disturbance.

The IMD did not see any significant change in maximum and minimum temperatures over northwest and adjoining central India during the next three days.
Strengthening of northwesterly winds over Indo Gangetic plains from tomorrow (3-Feb-10) onwards.
lowest minimum temperature of 2.6oC was recorded at Sarsawa (Uttar Pradesh).
Minimum temperatures are above normal by 2-4oC over parts of Rajasthan, Gujarat, north Konkan and East Madhya Pradesh
