Fleet-footed westerly exits as successor waits in the wings

A prevailing but fleet-footed western disturbance quietly made exit to the east overnight and away from Jammu and Kashmir, an India Meteorological Department (IMD) update said this morning.

Scattered light rain or snow has been reported from Jammu and Kashmir and Himachal Pradesh until the evening on Wednesday.

Isolated rainfall has occurred over sub-Himalayan West Bengal and Sikkim and mainly dry weather prevailed over the rest of the country during this period.

Maximum temperatures rose by 2-3 degree Celsius over parts of east Uttar Pradesh, central, east and northeast India.

They were above normal by 3-4 degree Celsius over Saurashtra, Kutch and Assam and below normal by 2-3 degree Celsius over parts of central India and near normal over the rest of the country.

The highest maximum temperature of 40.5 degree Celsius was recorded at Malegaon in Maharashtra.

Meanwhile, the exit of the western disturbance overnight might have been hastened by an overly impatient successor chugging its way in from across the border.

Spotted over north Pakistan yesterday, the fresh westerly system is now expected to start affecting the western Himalayan region mainly from the day after (Saturday), an IMD outlook said.

The configuration of supporting weather-making features over the rest of the northwest and eastern parts of the country has also undergone some change.

While the upper air cyclonic circulation over Punjab and neighbourhood persists, the ‘upper air trough couple’ towards the east has once again been whittled down to just one.

But importantly, the one that snakes its way down from coastal Orissa to the peninsular south is now headed into Kerala.

Satellite cloud imagery early on Thursday morning showed low to medium clouds over parts of northwest and adjoining central India, Bihar, Arunachal Pradesh and Karnataka.

A weather warning issued by the IMD said that isolated dust storms or thunderstorms would occur over Punjab, Haryana, Delhi, West Uttar Pradesh and north Rajasthan until tomorrow.

A short-term outlook said that isolated rain or snow would occur over western Himalayan region during Saturday and increase thereafter.

Scattered rain or thundershowers would occur over the Northeastern States until tomorrow (Friday).

Isolated rain or thundershowers has been forecast for north coastal Andhra Pradesh, Orissa, West Bengal, Sikkim, south Chhattisgarh and Vidarbha.

Isolated rain or thundershowers would also break out over south peninsular India and Andaman and Nicobar Islands.

Isolated dust storms or thunderstorms would roll out over Punjab, Haryana, Delhi, north Rajasthan and west Uttar Pradesh until Friday.

Maximum temperatures are expected to fall by 2-3 degree Celsius over the Indo-Gangetic until the weekend.

An extended outlook valid until Tuesday (April 12) said that fairly widespread rain or snow would occur over western Himalayan region and isolated dust storm or thunderstorm over adjoining plains of northwest India.

Scattered rain or thundershowers would occur over the Northeastern States and isolated over east and peninsular India.
