Since the last few days, the weather models are indicating some signs of rain in Bihar and Jharkhand. This would also happen to be the first spell of winter rainfall in the region.
The active and one of the most intense weather systems in the form of Western Disturbance has already approached the Himalayas. It will induce a Cyclonic Circulation over North Rajasthan, from which a Trough would extend up to the foothills of Bihar.
The rain belt would cover the Indo-Gangetic plains on December 11 extending from Northwest to East India gradually. The duo states of Bihar and Jharkhand would observe the first spell of winter rain tomorrow, with increased spread and intensity on December 13. Fairly widespread activities are likely to lash Bihar and adjoining East Uttar Pradesh on these two days. There are also chances of isolated hailstorm.
Due to rain, the winds would become easterlies, leading to a rise in the minimum temperature. Meanwhile, cloudy sky, windy days and increased humidity may cause a drop in the maximums. The feel-like factor will be much colder.
Despite the passage of the weather system on December 14, clouding will persist followed by light showers. Later, by December 15, rains would completely vacate the region.
Once the weather clears up, the cool north-westerlies would resume and minimums may drop to single digits. ‘Moderate to dense’ fog might take over the region along with cold wave conditions.
