Due to thunderstorms, resulting from W.D, over many parts of the Northern/Nort-Western regions of the country,maximum temperatures have fallen by 4-8°C over parts of west Madhya Pradesh, Maharashtra and Karnataka and by 2-3°C over parts of Punjab, Rajasthan, Uttar Pradesh and Rayalaseema. (Day temp map from Univ. of Cologne attached).The fall into the late 30s is very visible here.
The highest, 43.4c in India, was at Churu (Rajasthan) and Daltonganj.
Meanwhile, day temperatures have also dropped in Maharashtra, with Washim, recording the highest today of 42c. This fall is attributed to the light rains all over the state, as a result of a trough running from W.Bengal to the South-East Arabian Sea.

And, to the contrary, Mumbai has become worst off after a drizzle on Friday morning. S'Cruz was high at 37c, and the humidity factor was unbearable as it was partly cloudy in the day.
I do not expect this rain in Maharashtra to last beyond Saturday.

Heavy Rain in Assam, India

acquired April 16, 2010

acquired April 28, 2010

In mid- to late April 2010, torrential rains and violent winds downed electric lines, damaged homes, uprooted trees, and displaced some 150,000 people in the eastern Indian state of Assam, according to news reports. The hardest-hit area was Lakhimpur District, roughly 400 kilometers east of Assam’s principal city of Guwahati.
The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured these images of the area around Guwahati, which sits along the Brahmaputra River not far from the India-Bhutan border. The top image is from April 28, 2010, and the bottom image is from April 16, 2010. Both images use a combination of infrared and visible light to increase the contrast between water and land. Vegetation appears bright green and bare ground appears pinkish tan. Clouds appear sky blue. Water varies in color from electric blue to navy. The relatively light color of the Brahmaputra’s waters on April 28 likely results from the angle of sunlight.
Expanses of standing water surround the river on April 28, and the water sits on surfaces that had been relatively dry days earlier. Tributaries to the river, both east and west of Guwahati, are swollen in the later image.
The April floods in Assam were the second cluster of floods in that state in 2010, Sify News reported. The earlier round of floods struck the state the previous month, although with less severe effects.
