Another chilly morning greeted New Delhi on Wednesday with the minimum temperature plummeting by about four degrees after recording a rise in the last three days.

The minimum was recorded at 8.4 degree Celsius, down from Tuesday's 12.1 degrees.

The weatherman attributed to the moving away of western disturbance from the region.

The maximum was 23.1 degree Celsius on Tuesday.

The mercury has maintained a rising trend in the past three days with Sunday recording the season's lowest at 6.8 degree Celsius.

"This is a normal phenomenon during western disturbance. This sequence will be there till March. Whenever the western disturbance approaches a region, the temperature rises and when the disturbance leaves, it plummets," B P Yadav, Director of Indian Meteorological Department, said.

"As western disturbance approaches the north-western India, fluctuations in wind circulation are witnessed. Winds blowing from the mountains (from north-west) will withdraw and suddenly winds from the south (southerlies) will blow which is not as cool as the north-westerlies," he said.

The forecast said there could be a slight fall in minimum temperature in the next couple of days. Isolated to scattered showers are also expected in the capital in the next 24 hours.
