Temperatures in Delhi-NCR are likely to dip from Sunday, the India Meteorological Department has predicted, as cold northeasterly winds from the snow-covered mountains have already started blowing towards the plains.
The western disturbance, which had brought reprieve from a cold spell in large swathes of north and northwest India, has begun to retreat, it said.
Large parts of north and northwest India recorded below-normal maximum and minimum temperatures on most days this month before the western disturbance brought relief, an IMD official said.
This was due to a layer of dense fog persisting over the Indo-Gangetic plains for the past 10 to 11 days and a large gap between two western disturbances that allowed frosty winds from snow-clad mountains to blow in for a longer-than-usual period, he added.
