Minimum temperatures fell appreciably at one or two places over coastal and north interior Karnataka and parts of Tamil Nadu with the moist, warm easterlies being pushed into the extreme south.

Over northwest India, an incoming western disturbance has dropped anchor and is expected to cause scattered rain or snowfall activity during the next 24 hours. An approaching trough in the westerlies will further rev up the proceedings over the next two days.

Minimum temperatures are above normal by 3-5 deg Celsius over northwest and adjoining west-central India from warming induced by the ensuing cloud cover. They are above normal by 6-8 deg Celsius over west Rajasthan and parts of Gujarat.

An existing low-pressure area over southwest Arabian Sea is wilting under intense westerly wind activity. India Meteorological Department said that the ‘low’ has weakened into a trough in the region.

Its moisture content is getting sprayed as massive streaks in a north-northeast direction over Sindh (in Pakistan), Gujarat, Rajasthan and Jammu and Kashmir. This will fall as snow or thundershowers over the hills and plains of north and northwest India.

The elevated minimum mercury levels will stay as such for the next two to three days, subsequent to which they would gradually fall as the western disturbances passes away into the east.
