A prevailing western disturbance that helped light up the skies over the plains in northwest and east with some violent weather, is preparing to sign off.
But India Meteorological Department (IMD) has said that a successor system would troop in by the weekend, to take off from right where the predecessor ended.
The European Centre for Medium-Range Weather Forecasts, too, has agreed with the outlook for the impending westerly system.
What it would be capable of doing is sustain a churning cauldron of a trough extending from northwest India to east and northeast India with an occasional extension into east-central India.
The US National Centres for Environmental Prediction goes a step further to predict that the seasonal and destructive thunderstorms and dust storms could sustain into the week ending April 13.
A weather warning issued by the IMD on Tuesday evening said that isolated heavy rain would occur over Andaman and Nicobar Islands on Wednesday and Thursday.
Isolated dust storms or thunderstorms would occur over Punjab, Haryana, north Rajasthan and west Uttar Pradesh until Wednesday evening.
Extended forecast until Sunday said that the existing low-pressure area over the south Andaman Sea would cause widespread rain or thundershowers over Andaman and Nicobar Islands.
Widespread rain or thundershowers has also been forecast over the Northeastern States.
Earlier in the day on Tuesday, the IMD seemed to suggest that northwesterly winds have opened pincer-like “assault fronts” over northwest and along east and northeast India.
Queering the pitch was the cross-over of an induced upper air cyclonic circulation from its overnight perch over central Pakistan and adjoining northwest Rajasthan and Punjab.
The IMD had traced the circulation as having dropped anchor over Punjab and adjoining north Rajasthan and Haryana.
TROUGH SPRINGS OPEN
In the evening bulletin, the IMD said that the induced upper air cyclonic circulation persisted, but, significantly enough, a trough extended from this system to Jharkhand.
Another upper air cyclonic circulation lain over extreme south peninsular India.
Meanwhile, an IMD update for the 24 hours ending on Tuesday morning said that fairly widespread rain or snow occurred over Jammu and Kashmir.
