Next easterly wave will hold over southern extreme of India from 5-Apr to 14-Apr ... http://bit.ly/aolAiq
Intense heat awaits central parts again
A high-pressure area extending from the northwest Pacific is forecast to enter peninsular India from Wednesday bringing a wave of intense heat, according to the European Centre for Medium-Range Weather Forecasting (ECMWF).
The heat would be felt over east-central India to start with, and extend gradually to central India and west-central India, ECMWF said in its forecast update on Monday.
UPWARD CLIMB
Mercury is likely to witness an upward climb in this manner – over Orissa, Vidarbha, Chhattisgarh, east Madhya Pradesh, Marathwada and madhya Maharashtra.
The heating trend is forecast to head north-northwest from April 8 to become concentrated over the familiar outback of Gujarat and southwest Rajasthan.
An India Meteorological Department (IMD) update on Monday indicated a slight rise in maximum temperatures over central and east India during the next three days up to which forecasts were available.
The US National Centres for Environmental Prediction (NCEP) does not see the possibility of thundershowers unfolding over any part of this region during this phase but has made an allowance for the south.
Rain or thundershowers could break out over southern Tamil Nadu and adjoining Kerala as another easterly wave comes calling into the extreme Bay of Bengal around April 5 and proceeds to move west.
The resulting wet phase over the southwest coast and southern peninsula may last until April 14, though the showers would be sporadic and distributed far and wide.
FRESH WESTERLY
Meanwhile, an IMD update said on Monday that a fresh western disturbance has entered the northwest and was parked over north Pakistan and adjoining Jammu and Kashmir.
Isolated to scattered rain or snow is likely to occur over the western Himalayan region during the coming three days. IMD sees a follow-up system reporting in around Thursday.
Towards the east, westerlies have helped accentuate weather over east and northeast India.
The causative weather-making trough in the region ran down from Bihar to Orissa on Monday.
Strong winds prevailed over the Indo-Gangetic plains at the lower levels.
CLOUD IMAGERY
Moisture incursion over the northeastern States from the Bay of Bengal is expected to continue for another five days.
Satellite imagery showed the presence of low-to-medium clouds (partly clouded conditions) over parts of Jammu and Kashmir, Himachal Pradesh, the northeastern States, peninsular India, south Bay of Bengal and southeast Arabian Sea.
Forecast until Thursday spoke about the possibility of scattered to fairly widespread rain or thundershowers accompanied by isolated thunder squalls over the northeastern States.
Extended outlook until Saturday said that fairly widespread rain or thundershowers accompanied by isolated thunder squalls are likely over the northeastern States. Isolated rain or thundershowers have also been forecast over south Tamil Nadu, Kerala, coastal Karnataka, Lakshadweep and Andaman and Nicobar Islands.
Heat wave conditions have prevailed over many parts of west Rajasthan, Uttar Pradesh, north Madhya Pradesh, parts of Bihar and isolated pockets of Jharkhand, Chhattisgarh and Orissa during the past 24 hours ending Monday morning.
A warning issued by IMD said that heat wave conditions may continue to hold over parts of south Uttar Pradesh, isolated pockets of northeast Madhya Pradesh, Bihar, Jharkhand and interior Orissa during the next 24 hours. Isolated heavy rainfall accompanied by thunder squalls may occur over Arunachal Pradesh, Assam and Meghalaya during the next two days.
