The Western Disturbance which is going to affect the Western Himalayas and adjoining Northern Plains between March 28 and 30, will have its impact on East India as well, beginning March 31. A trough is also expected to extend from Haryana up to Uttar Pradesh on March 31, leading to scattered rain and thundershower activities over many parts of the state. Thereafter, this trough will further extend up to Bihar. By April 1, rains would have decreased over Uttar Pradesh. However, the eastern parts of the state would continue to receive light rain at one or two places.
The intensity will however be good over Bihar during this period (Between April 1 and 2). On April 2, the eastern parts of the state may witness lightning strikes accompanied with strong winds.
By April 3, the weather system will start degenerating as the trough will start weakening and may move towards the northeastern states. On April 3, we only expect isolated light rain over Bihar, clearing thereafter.
Therefore, April will commence on a rainy note for the eastern parts of the country. Not only Bihar but many parts of West Bengal and Jharkhand may also receive rain and thundershower activities April 1 onward.
