“Extremely cold winds are blowing from the Western Himalayan region where there was widespread snowfall last week. Low cloud conditions are blocking sunshine in some areas which is leading to very low maximum temperatures in some places over NW India,” said Kuldeep Shrivastava, head, regional weather forecasting centre.
According to IMD, a cold day or severe cold day is classified as such on two parameters—a minimum temperature of under 10°C (and maximum temperature of 4.5°C or 6.4°C below normal).
