Mussoorie and Nainital are likely to observe light rainfall.
Western disturbance will have an induced cyclonic circulation over parts of Punjab and Rajasthan. This will change the wind pattern across the plains of North India. Therefore, twist in the weather conditions is likely over these parts. Foothills and adjacent parts can expect light rain. Jammu, Kathua, Pathankot, Gurdaspur, Ropar, Chandigarh, Rishikesh and Dehradun are likely to have cloudy sky and fleeting showers on 20th and 21st Feb.
Change in the wind pattern will raise the minimum temperatures across the plains. Arrest of winds down the slopes of mountains may even increase the day temperatures, as well. A short break is expected on 22nd Feb and another system is expected from 23rd Feb onward.
