India's Skies Divided: Snow in Mountains, Delhi Chokes, 97 Flights Cancelled Amid Fog

• North India experienced extreme weather: snowfall in mountains (Kashmir, Gulmarg) and dense fog in plains (Delhi, Punjab, UP).
• Delhi faced 'very poor' to 'severe' air quality (AQI 377) and dense fog, leading to 97 flight cancellations and over 200 delays.
• Kashmir welcomed 'Chillai-Kalan' with snowfall, ending a dry spell and bringing relief to the region.
• Plains of Punjab, Haryana, and Uttar Pradesh saw 'Cold Day' conditions and near-zero visibility due to dense fog.
• Jharkhand issued an orange alert for fog and cold; South India (Karnataka, Telangana) also experienced cold waves.

Why It Matters: India faces a stark weather divide: snow in hills, severe fog and pollution in plains, disrupting life and travel.
