The westerlies over N-W and Central India is almost ZERO and will stay that way till 16-Mar. And almost NO W.D forecast as well.

An easterly wave along with a UAC might affect coastal Tamilnadu from 13-Mar till 15-Mar... this will slightly reduce the abnormal heating

Maximum surface heating is tending to grow its footprint from western India to central and east-central India in phases over the next few days.
Minimum temperatures were below normal by 2 to 3 deg Celsius over isolated pockets of central, east and south peninsular India during the last 24 hours ending Wednesday morning.
The lowest minimum of 8.6 deg Celsius was recorded at Adampur in Punjab during this period. The minima were above normal by 2 to 3 deg Celsius over parts of Maharashtra and isolated pockets of north Rajasthan, Uttar Pradesh, Bihar, west Madhya Pradesh, Assam and Gujarat.
Lack of intense western disturbance activity and cloudless skies would help both maximum and minimum temperatures to inch up.
The prevailing feeble western disturbance over Jammu and Kashmir and neighbourhood is in the process of moving further east and exiting the country.
There is no forecast of any big western disturbance activity in the short-to-medium term to put any meaningful cap on surface heating.
Meanwhile, isolated light rain or snowfall has been reported from Jammu and Kashmir and Himachal Pradesh as the feeble westerly toyed with the fringes of the hills of northwest India.
Isolated rainfall has occurred also over Haryana and north Rajasthan in the adjoining plains and Sikkim, Assam and Arunachal Pradesh in east and northeast India.
Satellite cloud imagery on Wednesday afternoon showed the presence of convective (rain-bearing) clouds over parts of east Jammu and Kashmir, southeast Bay of Bengal and Andaman Sea.
The clouding in the Bay and the Andaman Sea is attributed to a prevailing easterly wave affecting the Andaman and Nicobar Islands.
The wave will probably throw up an upper air cyclonic circulation over southeast Bay of Bengal by Friday, the IMD said.
Some of the global models said that a rain wave piloted by the circulation would descend over southeastern Tamil Nadu and adjoining Kerala during the weekend.
The resulting rains could last for a couple of days, these models suggested.
Meanwhile, a short-term forecast by the IMD said that isolated rain or snowfall would occur over western Himalayan region until Friday morning
In early March 2011, over a period of just six days, the appearance of Australia’s Channel Country changed dramatically. Rainwater filled typically dry river channels throughout the region, particularly in southwestern Queensland.
The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured these images of southwestern Queensland and northeastern South Australia on March 2, 2011 (top), and March 8, 2011 (bottom). Both images use a combination of infrared and visible light to increase the contrast between water and land. Vegetation, even sparse vegetation, appears bright green. Clouds appear sky blue. Water varies in color from electric blue to navy. Bare ground appears pink-beige.
On March 2, water fills just a few channels and basins. Six days later, standing water is apparent throughout southwestern Queensland and northeastern South Australia. The largest expanses of water appear just north of the border between the two states.
Channel Country flooding is a fairly common occurrence at this time of year, but the summer of 2010–2011 proved to be one of Australia’s wettest on record, leading to extensive flooding. Agence France-Presse reported that Australia’s Bureau of Meteorology described average rainfall as 70 percent above normal. Topped only by precipitation received in 1973–1974, rainfall for 2010–2011 was the second-highest since recordkeeping began 111 years earlier. Meteorologists attributed the unusually heavy precipitation to La Niña weather patterns.
