North-west looking for rains as westerly sets up perch
Rainfall scenario over north-west and central India for January continues to be dismal with the region recording scanty rainfall until Wednesday up to which figures were available.
An India Meteorological Department (IMD) update said that this was in dire contrast to the situation obtaining in peninsular India where the entire region, except Tamil Nadu and Pondicherry, has recorded excess rainfall.
EXCESS IN SOUTH
At least 12 meteorological sub-divisions, all in the peninsula, recorded excess rainfall, while two (again in the south) recorded normal rainfall. Tamil Nadu and Pondicherry found itself in the “deficient” category even as the north-west, central and east has had to contend with “scanty” rainfall.
But a precipitation outlook of the US National Centres for Environmental Prediction (NCEP) continues to indicate the probability of isolated showers for the north and north-west during the period until February 14.
The region gets most of its rain from passing western disturbances, one of which is currently positioned over North Pakistan and adjoining Jammu and Kashmir.
Satellite cloud imagery showed convective clouds over parts of Jammu and Kashmir while low to medium clouds were seen over parts of the western Himalayan region and Punjab.
An IMD outlook said that the western disturbance would continue to impact the western Himalayan region and adjoining northern plains during the next 24 hours as well.
RAINS FORECAST
Forecast valid until Monday said that scattered to fairly widespread rain or snow but moderate in intensity would occur over western Himalayan region during next 24 hours and decrease thereafter. Isolated rain or thundershowers has been forecast for the plains of northwest India, too.
The western disturbance with its ‘heat engine' up front has warmed the plains of the northwest with both maximum and minimum temperatures looking up.
The IMD update said that minimum temperatures were above normal by as much as 6 to 8 deg Celsius over parts of west Rajasthan, Jammu and Kashmir and by 2 to 4 deg Celsius above normal over Uttar Pradesh, parts of Gujarat, Konkan and Goa.
They were near normal over remaining parts of northwest India while being below normal over many parts of east India where the inbound western disturbance has not exerted its influence as yet.
The lowest minimum temperature of 5.5 deg C was recorded at Shahjahanpur during the 24 hours ending Friday morning. This provided evidence to the fact that the regions with the least minimum temperatures had shifted out of the northwest.
Maximum temperatures were above normal over Jammu and Kashmir, Himachal Pradesh, Rajasthan, Haryana, parts of west Madhya Pradesh, the northeast, Uttar Pradesh and parts of Gujarat, Konkan and Goa.
Scattered light to moderate rain or snow has occurred over Jammu and Kashmir during the 24 hours ending Friday morning. The IMD has ruled out the possibility of dense fog conditions being thrown up over the plains for at least the next three days.
But maximum and minimum temperatures are expected to fall on Saturday and Sunday as the skies clear up with the away-movement to the east of the prevailing western disturbance
