A significant weather shift is underway across multiple states in the country, with heavy rains and bitter cold reported in various regions. The formation of a low-pressure zone in the Arabian Sea has ushered in steamy winds from the Bay of Bengal, elevating temperatures and creating a cloudy atmosphere. The Indian Meteorological Department (IMD) anticipates heavy rainfall in Maharashtra and other states over the next 48 hours.

According to Skymet Weather, a complex atmospheric interplay involving cyclonic circulation, low-pressure troughs, and an anticyclone has established a 'confluence zone' over Madhya Pradesh and Uttar Pradesh. This convergence results in thunderstorms and rainfall in these regions, extending to parts of Chhattisgarh, Jharkhand, and Bihar.

While North India, including Delhi, contends with bitter cold, dense fog is impacting visibility, affecting railway and air services. A yellow alert has been issued by the regional meteorological department. Simultaneously, mountainous areas experience colder temperatures due to snowfall, leading to a forecasted drop in mercury levels on January 4.

Pune and its surroundings are expected to remain partly cloudy with a possibility of light rain in the coming days. The weather dynamics present a contrasting meteorological tableau across the nation, showcasing the diverse impacts of atmospheric interactions.
