Night Mercury Plunges to 19.5°C as IMD Sounds 48-Hour Rain Alert

A noticeable atmospheric transition has swept across Bihar over the past 24 hours, bringing unseasonal precipitation, gusty winds, and a sudden evening chill across several districts. According to the latest bulletin from the Meteorological Centre in Patna, scattered light to moderate showers hit multiple belts across northwestern, north-central, south-central, and southeastern regions of the state. The most intense localized downpours were registered at Chakai with 58.6 mm of rainfall, closely followed by Lakhisarai logging 38.2 mm alongside squally surface winds gusting up to 24 kmph, triggering daytime temperature drops of 2 to 5 degrees Celsius across several agricultural zones.Arwal Shivers as State's Coldest Pocket While Kaimur Tops Maximum Temperature ChartThe sudden cloud cover and precipitation patterns produced wide thermal disparities between northern plains and southwestern border regions. Arwal emerged as the coldest spot in the state, recording an overnight low of 19.5°C, while broader nocturnal temperatures fluctuated between 19.4°C and 24.9°C to usher in early morning chill. In contrast, the mercury peaked at 32.7°C in Kaimur (Bhabua), maintaining the state's highest maximum reading. Overall, day temperatures across districts hovered within the range of 23.6°C to 32.7°C, with lingering dampness tempering the daytime heat in areas that received sustained rainfall over the weekend.Rain Forecast for Northwestern Districts and Bay of Bengal Depression StatusMeteorologists at the Patna observatory project that day temperatures will climb moderately by 1 to 4 degrees Celsius over the coming 48 hours as convective activity subsides, with no sharp fluctuations expected in nighttime readings over the subsequent three to four days. However, isolated light rainfall remains on the radar for November 2 across northwestern pockets, specifically covering West Champaran, East Champaran, Siwan, Saran, and Gopalganj. Weather analysts note that the prevailing atmospheric instability is being driven by an active cyclonic circulation situated over southeastern Uttar Pradesh and neighboring zones between 1.5 km and 3.1 km above sea level, while an intensifying deep depression over the Bay of Bengal tracks toward the Andhra Pradesh coastline without posing direct cyclonic hazards to the Gangetic plains.
