The incoming big western disturbance with an embedded low-pressure area bid its time over Afghanistan-Pakistan to cross over into North-West India and set up unruly weather in the region.
The entourage has a sweep arching down towards the south Gujarat, and promises to set off thunderstorms and thunder squalls to area to its north.
This is despite the outlook for the low-pressure area weakening appreciably just as it crosses the international border into North-West India.
A weather warning issued by the India Meteorological Department (IMD) said that thunder squalls (a narrow corridor of stormy weather) would stalk one or two places over Rajasthan during next two days.
Thunder squall has also been forecast over Punjab, Haryana, Uttarakhand and Himachal Pradesh and the Jammu division of Jammu and Kashmir during this period.
An outlook for the next three days said that rain or thundershowers would occur at one or two places over Jammu and Kashmir on Tuesday.
A similar forecast is valid for one or two places over Himachal Pradesh and Uttarakhand from Tuesday, which would hold on for a while.
Rain or thundershowers has been forecast over Rajasthan, Gujarat, Punjab, Haryana, Delhi and west Uttar Pradesh from Tuesday.
Maximum temperatures are expected to rise by 2-3 deg Celsius over the plains of North-West and adjoining East and Central parts during next two days.
The east-northerly track will bring the western disturbance winding its way into Assam, Arunachal Pradesh and Nagaland and set up weather over these regions as well.
SHOWERS IN SOUTH
Meanwhile, elsewhere in the country, a weather-setting trough continued to run down from Vidarbha to south Tamil Nadu across interior Andhra Pradesh. The other trough lay extended from Assam to Odisha across Gangetic West Bengal.
The IMD has forecast rain or thundershowers at one or two places over Tamil Nadu and Kerala.
Extended forecast valid until Monday next said that thundershowers would break out over Sikkim, Arunachal Pradesh, Assam, Meghalaya and Nagaland and at one or two places over the peninsula.
Thundershowers have also been forecast for Odisha and Gangetic West Bengal during this period.
