*North India*

A strong Jet Stream across the North Indian plains, with winds at 150 knots,  has caused an High Pressure Region ( due to convergence).

This has resulted in

* Thick fog in the plains 

* Sharp drop in day and night temperatures. Almost sub zero temperatures. 

*The places in the plains of Punjab, Haryana, Rajasthan and Delhi are colder than the Himalayan hill stations at night.
