Usually, Western Disturbance starts affecting the hills and adjoining plains of North India October onward and continue to prevail until the end of February and at times even up to March.
These systems after approaching the region usually affect it for a day or 2 and are largely responsible for giving rain and snow of varying intensity.
At present, a fresh Western Disturbance is seen over North Afghanistan and adjoining Pakistan. It is expected to affect the Western Himalayas by November 17. This system will be confined to the upper reaches, hence no significant rain or snow activity is expected over the lower and middle levels.
Due to change in wind direction, which will be for a brief period, minimum temperatures are expected to marginally rise across most parts of Jammu and Kashmir, Himachal Pradesh and North Punjab.
This year, weather has remained dry since October no active Western Disturbance has given any significant rain or snow.
As per Skymet Weather, till the time there is no moderate or heavy snow recorded, temperatures will not see any significant drop in northern plains of India. Moreover, the flow of northwesterly cool winds from the hills to the plains may perhaps aid in lowering the temperatures.
