Kolkata: The city woke up with a sharp cold on Monday even when the minimum temperature dropped to 11.2 degrees Celsius, the lowest season so far.
With the northwest wind getting stronger, mercury will dip further and maybe slid up to 10 degrees on Tuesday, the Met Office said.
Cold spells, however, can be damaged on Wednesday because northwest begins to lose intensity.
But mercury may still remain below 15 degrees.
The temperature has been on a stable slide since the beginning of last week when the minimum temperature dipped three degrees from 18 to 15.
Since then, it remains below 15 degrees Celsius, inches gradually to slide below 12 degrees on Monday.
“Northwesterly has gained gradual strength because there is no obstacle on the road.
From Wednesday, however, some east winds will embed in moisture and can hinder the flow.
This will help the mercury increase slightly and coldly will lose its sting,” said Director of the Regional Meteorology Center ( RMC) GK DAS.
He added Christmas can still be cold enough in Kolkata.
Western disorders are expected to intervene to the northwest lane and slow down the intensity.
This mercury is expected to drift around 14-15 degrees on December 25.
“After the north weakens, both the minimum and maximum temperatures will rise.
But it may not continue long,” said the watershed.
This is the first Chilly Mantra in Kolkata this winter.
The city experienced at least three, where Mercury plunged.
Rise up and the fall of mercury depends on the northwest wind flow that carries the cold from the peak of the Himalayan ice.
This is often disturbed by the weather system, such as low pressure troughs along the path or east wind attack from the sea.
This season, it happened during the second week of December when a low pressure trough has caused clouds and drizzle, pushing the minimum temperature up and pulling up to the bottom.
The difference between the two is narrowed into only two degrees.
The minimum temperature of Monday is four notches below normal.
A maximum of 22.8 ° Celsius – is four degrees below normal too.
Mercury can slide to 10 degrees Celsius in Kolkata today
