"Likely cloud cover and enhanced humidity could lead to further gradual increase in night minimum temperatures over parts of northwest India, thereby reducing the severity of cold wave conditions during next 24 hours. However, dense fog conditions are likely to occur during late night to morning hours over these regions, especially on January 2 and 3," the weather agency said in a bulletin.
The IMD further said that another active western disturbance is likely to cause widespread rain and snow with isolated heavy falls over western Himalayan region and scattered to fairly widespread rainfall with isolated hailstorms over parts of Punjab and Haryana, Chandigarh and Delhi on January 4 and 5.
