North Indian plains had seen an increase in the minimum temperatures with some parts of the plains even recording minimums above 10 degrees. Moreover, these temperatures increased due to the presence of the Western Disturbance over the Western Himalayas which did dump some rain and snow over the higher reaches.
The system moved away yesterday after which cold northwesterly winds have started to blow over the plains of North India. In view of this, minimums have seen a significant drop as compared to yesterday. Moreover, from 10 degrees Celsius, Delhi NCR has seen its minimum drop to 5.5 degrees Celsius.
In fact, other parts of North India have also seen a similar drop in the minimums. Now also, minimum temperatures will continue to witness a drop and many parts of the Northern Plains may observe cold wave conditions.
These conditions will last for at least the next 5-6 days as no Western Disturbance is likely to make an appearance in the next few days. Due to light winds, dense fog will also be seen over some parts of North India during the morning hours.
Moreover, in the next few days, cold day conditions may be seen in some parts of North India. Thus, wintry chill is all set to stay for some time. Slight relief is only likely around January 6 or 7.
