The customary chill has gone missing from the November morning air and weather officials have blamed it on a Western Disturbance in Kashmir that is blocking the cold north-westerly wind.

The minimum temperature had been hovering around the 18-degree mark over the past two days, before reaching 19.1 degrees Celsius, a notch above normal for this time of the year, on Monday.

A Met official ruled out a dip in the night temperature over the next couple of days.

A cyclonic circulation over east Uttar Pradesh and adjoining west Bihar has led to a rise in the moisture content in the city air and contributed to the lack of chill.

“At the moment, there is a Western Disturbance in Kashmir. So, the north-westerly wind has not been blowing into the city for the past two-three days,” said Sanjib Bandyopadhyay, deputy director general, India Meteorological Department, Calcutta.

The mercury is expected to dip once the Western Disturbance clears and the cold winds start blowing in.

But Met officials remained non-committal on the arrival of winter in the city.
