Unstable weather to persist over large parts of country
With a fresh western disturbance expected to cross into the western Himalayas and the adjoining plains of northwest India, regional weather is expected to remain unstable during the weekend and into the next.
The rumble would also be heard in distant east and northeast India as well as the south, as offspring troughs and associated circulations dig in over these regions.
WEATHER WARNING
An India Meteorological Department (IMD) update on Thursday evening said that the fresh westerly would start affecting the western Himalayas and adjoining plains from Friday onwards.
An upper air cyclonic circulation in the lower levels over Bihar and neighbourhood persisted from overnight as did a counterpart circulation over Nagaland.
A weather-making trough lay extended from southwest Madhya Pradesh to coastal Kerala across Maharashtra and Karnataka.
A weather warning valid until Saturday said that isolated thunder squalls would occur over Bihar, Jharkhand, Chhattisgarh, Orissa, West Bengal and Sikkim.
Global weather models also indicated that the unstable weather (as distinct from stable or clear) would spill over into the next week.
WIDESPREAD RAIN
The 24 hours ending on Thursday morning said that fairly widespread rain or snowfall was reported from Himachal Pradesh while it was scattered over Uttarakhand and isolated over Jammu and Kashmir.
Fairly widespread rainfall also broke out over Assam, Meghalaya and Kerala; scattered over Uttar Pradesh, Karnataka, Lakshadweep, Orissa, sub-Himalayan West Bengal, Sikkim and Chhattisgarh.
It was isolated over Madhya Pradesh, Maharashtra, Andhra Pradesh, Jharkhand, Bihar, Gangetic West Bengal, Tamil Nadu and Andaman and Nicobar Island.
Satellite pictures on Thursday afternoon revealed the presence of convective (rain-bearing) clouds over parts of sub-Himalayan West Bengal, Sikkim, the Northeastern States, south interior Karnataka and southeast Arabian Sea.
MORE RAIN SEEN
A short-term IMD outlook valid until Sunday said that widespread to fairly widespread rain, thunderstorms and dust storms would be unleashed over most of these areas in varying intensities.
An extended forecast valid until Tuesday said that scattered rain or snow would occur over the western Himalayan region.
