Yes ! The monsoon should push down southwards now, from Thursday. The 200 hpa winds do indicate the same, as the winds are seein veering around the 20N line today.
For the north, look out for drop in night temperatures from the 8th. itself. Those regions with night temperatures in the early 20s, will drop to 18/19c, and those regions in the late 20s, will go down by 3/4c, next few nights.
The deficit climbed up close to the 23.9 % recorded in recent memory (1972). The next worst is the 24.9 % recorded way back in 1918. And 1899 was -26%. Lowest ever was 1877 at -29%.
