Back-to-back western disturbances would keep the weather on a boil over northwest and east India during the weekend.
India Meteorological Department (IMD) has said in an evening outlook that the fairly widespread rain or thundershowers over the Northeastern States would sustain until Monday.
Global models are of the view that an incoming western disturbance into northwest India may hold fort for an extended period into the next week.
It may also go on to fuel thunderstorm activity to the east of the country as well as the northeast by April 9, these forecasts said.
The IMD said that scattered rain or snowfall would occur over western Himalayan region and isolated dust storm or thunderstorms over the plains of northwest India until Monday.
A short-term warning said that isolated thunder squalls would break out over east Uttar Pradesh, Bihar and Jharkhand until Friday.
Meanwhile, an update of weather over the last 24 hours ending on Wednesday morning said that widespread rain or snowfall was reported from Jammu and Kashmir and Himachal Pradesh.
It was fairly widespread over Uttarakhand and scattered over Haryana, west Uttar Pradesh, sub-Himalayan West Bengal, Sikkim, the Northeastern States, Kerala and Andaman and Nicobar Islands.
The rain was isolated over Punjab, east Uttar Pradesh and Tamil Nadu. The seasonally unstable weather is generated from the passage of cooler westerly to northwesterly winds over heated up surface.
Minimum temperatures rose by 2 to 3 deg Celsius over parts of northwest India while they fell by 2 to 3 deg Celsius over parts of the Northeastern States.
They fell by a similar margin also over parts of western Himalayan region, south Madhya Pradesh, Vidarbha, Marathawada and Telangana.
Global long-term forecasts had suggested that peninsular India might witness cooler than normal climes during the spring and pre-monsoon season.
Satellite pictures on Wednesday afternoon showed the presence of convective clouds over parts of southeast Andaman Sea from a persisting low-pressure.
Meanwhile, an upper air cyclonic circulation thrown up by the exiting western disturbance moved in over central Uttar Pradesh with a trough extending to north Orissa.
Short-term forecasts said that scattered rain or snow would occur over Jammu and Kashmir and isolated over Himachal Pradesh and Uttarakhand until Friday and increase thereafter.
