Mercury looks up over North ahead of westerly
Minimum temperatures have looked up by 2 to 4 deg Celsius over parts of Haryana, Punjab, north Rajasthan and Gujarat ahead of arrival of a fresh western disturbance with its warming anomaly upfront.
An India Meteorological Department (IMD) update on Thursday said that the remaining parts of northwest, central and adjoining east India saw lesser warming due to the fading proximity factor.
LOWEST MERCURY
The lowest minimum temperature of 3.3 deg C during the last 24 hours ending Thursday morning in the plains of the country was recorded at Narnaul in Haryana. The incoming feeble western disturbance would affect western Himalayan region on Friday.
The IMD expects to see further rise in minimum temperatures by 1 to 2 deg Celsius over many parts of northwest, central and adjoining east India on Friday.
Isolated rain or snow may occur over Jammu and Kashmir, Himachal Pradesh and Uttarkhand on Friday.
COLDER WINDS
But minimum temperatures will look down after the western disturbance moves out to the east, making the way clear for colder nortwesterly winds to fill the plains. Meanwhile, in the south, an easterly wave is expected to affect parts of south peninsular India from Friday.
CONVECTIVE CLOUDS
Satellite cloud imagery on Thursday afternoon showed the presence of rain-bearing clouds over parts of north Kashmir, south Bay of Bengal, southeast Arabian Sea and south Andaman Sea.
Isolated rainfall has already been reported over Andaman and Nicobar Islands during the 24 hours as the easterly wave drifted in from the southeast Bay of Bengal. The weather was largely dry over the remaining parts of the country during this period.
An outlook valid until Sunday said that dry weather would prevail over the plains of northwest, west, central and east India.
Scattered rain or thundershowers are expected to occur over the Andaman and Nicobar Islands.
Isolated rain or thundershowers has been forecast over Kerala, Tamil Nadu and Lakshadweep. But rainfall may scale up over Tamil Nadu from Friday onwards, the IMD said.
According to the European Centre for Medium-Range Weather Forecasts, the major weather system to look forward to is a deep trough expected to arrive over southwest Rajasthan and adjoining Gujarat during next week.
A few international weather models have been forecasting possibility of scattered rains for parts of central and northwest India as the deep trough ploughs its way into the east and interacts with monsoon easterlies from the south.
