Why was Delhi colder than Shimla & Mussoorie on Monday?

Delhi and other plains recorded temperatures lower than hill stations like Shimla and Mussoorie on Monday, and IMD Director General M Mohapatra blamed it on a western disturbance. "The night was cloudy over the higher reaches, which is why minimum temperatures remained higher there," he said. In plains, clear skies and persistent cold northwesterly winds led to a temperature drop.
