The prevailing western disturbance over Jammu and Kashmir has refused to not just blink as a successor waited its turn across the border but also defy the forecaster’s bidding.



An India Meteorological Department (IMD) outlook said that it won’t be until Monday that the incoming system would be allowed in, especially after the incumbent upped the ante by throwing up an induced cyclonic circulation over Haryana.



A secondary circulation induced by a western disturbance over northwest intention goes to reflect its staying power and growing intensity.



This is not the first time that a westerly system has gone on to spook benign outlook and showed its true intent, setting off unstable weather all along the plains of northwest India.



An IMD update until this (Saturday) morning said that widespread rain or snowfall has occurred over Jammu and Kashmir while it was fairly widespread over Himachal Pradesh, and scattered over Uttarakhand.



In the plains, widespread rainfall has occurred over Haryana, Delhi during the period under reference.



It was fairly widespread over Punjab; scattered over Uttar Pradesh, west Rajasthan, east Madhya Pradesh, sub-Himalayan West Bengal, Sikkim, Jharkhand and Chhattisgarh; and isolated over east Rajasthan and Bihar.



In the south, it was fairly widespread over Vidarbha, Telangana, Andaman and Nicobar Islands and Lakshadweep and isolated over Madhya Maharashtra, Marathawada, south interior Karnataka, Kerala and Tamil Nadu.



Satellite imagery this (Saturday) morning showed the presence of convective (rain-bearing) clouds over parts of western Himalayan region, northwest Uttar Pradesh, south Bay of Bengal, Andaman Sea and southeast Arabian Sea.



Short-term forecasts valid until Tuesday (March 1) said that fairly widespread to scattered showers may break out over northwest India, east India and parts of east-central India and peninsular south.



Extended forecast valid until Thursday next said that fairly widespread precipitation would occur over western Himalayan region and isolated to scattered rain or thundershowers over adjoining plains.



This could also indicate the possibility of arrival of a fresh western disturbance into northwest India by mid-week next week.
