Heat Wave in Indian Sub-Continent:
The Indian Sub-Continent specially the central, North-Western and Northern regions,has been in the grip of a severe heat wave since the begining of April. The Temperature Anomaly Map shows the North-West in severe Dark Red heat, and major portions of the Sub-Continent in the red, save the South.
April has seen some "severe above normals". A few of the "Hot Spots" of the last couple of days:
Delhi: Palam 42.8c. S'Jung 41.6c    West Bengal: Daltongunj 44.6c, Bankura 43.8c.
 Orissa: Jharsuguda 45.2c, Titalgarh 45.2c.    Bihar: Gaya 44.8c.     U.P: Sultanpur 45.2c, Varanasi 45c.
 Gujarat: Bhuj 43.7c, Ahemdabad 42.4c, Rajkot 42.2c.
 Maharashtra: Chandrapur 45c, Nagpur 45c, Pune 41c, Mumbai 38c.
    Pakistan : Nawabshah 47c.
The Day Temperature Map of Tuesday, 13th, does not show much relief, with 45's scattered all over the Central and East India, and in Pakistan.

The heat is attributed mainly to the North-Westerly winds sweeping the plains of Northern region, and the absence of a real effective W.D. The W.D. is absconding due to a ridge of High sitting firm on the North-Western region.

Meanwhile, just got news (10pm Tuesday) of "very good " rain, or rather thundershowers , from Banglore. What a relief! I understand almost the entire state of Karnataka has recieved good rains this evening, anf the "line of wind discontinuity" has been a boon to the region.
