A late night update from India Meteorological Department (IMD) on Thursday mentioned the south-westerly winds from the ‘low’ and an accompanying cyclonic circulation have been fanning in lots of moisture from the Arabian Sea and will do the very same in excess of the Bay of Bengal as it travels East across East and North-East India.
Snow, showers for hills, plains
The dampness introduced in by the western disturbance and the ‘low’ will get blown against the heights of the Himalayas further in North and North-East, and into the plains of North-West India cooled so significantly by the north-westerly winds, forming clouds. Shift in wind direction as well as embedded dampness will translate into snowfall in the hills and showers/rain together the plains.
This is even as the cumulative rainfall so considerably for the state as a entire through the winter season (January 1-February 2) logged in at 116 per cent previously mentioned the very long-period average, and as higher as 122 per cent for North-West India by yourself.

Quite widespread to widespread mild/reasonable rain and thunderstorms/lightning might go on to lash Bihar and Jharkhand on Friday.
A related sample is predicted for West Bengal, Sikkim and Odisha with chance of isolated hailstorms on Friday. Isolated hefty rain may perhaps split out over Bihar, Jharkhand, West Bengal and Sikkim.
