A severe HOT conditions expected from 15-May for N,N-W and Central India .. http://ow.ly/i/C9Xv

Monsoon Watch-Seasonal Low parameter:


With the heat factor still lacking absolute "full strength", in the Northern regions, the Seasonal Low core in the Thar Desert is now somewhat "unsteady", with a core pressure at 1002 mb, and requires to spread more westwards, rather than east. This (pulling Eastwards) is happening due to M1. 


The heat waves are still missing, with the minimums still showing vast regions in the below normal range. By this time each year, vagaries normally charts the "above 30c" minimums. But this year as yet, forget 30s, we are still barely reaching 25s in the night, with the odd one out in the NW plummeting to below 20c.
And the days ? 45c is just about getting its foothold!
