The IMD said it was the coldest night of the month in Hisar since 1973 when the mercury plummeted to minus 1.5 degrees.

Haryana's Narnaul saw a minimum of minus 0.5 degree Celsius, while it was zero degree in Punjab's Bathinda.
Chandigarh recorded a minimum temperature of 2.7 degrees, while it was 1.6 degrees in the holy city of Amritsar and 4.1 degrees in Ludhiana.
