A strong western disturbance is expected between January 3-7, which should bring moderate-to-heavy snowfall over hills in Jammu and Kashmir, Himachal Pradesh and Uttarakhand.
At the same time, an induce cyclonic circulation over Haryana is likely to shower light-to-moderate rain in Punjab and Haryana between January 6-10.
Delhi may receive light rain on January 6 or 7.
