Chennai Rains Decreasing from next Tuesday (23rd), and Mumbai stuffy and hot weather coming this weekend ..Delhi getting cooler !

An UAC, descending down to 925 hpa levels has formed near North Sri Lanka at around 10N, and extended clouding associated with the system is more in the Northern quadrant due to strong "incoming" NE winds from the Bay. 
System will move West, roughly along the 10N line, as the trough (axis) runs along this line, and may sustain as a Low. The high pressure in the Arabian Sea prevents the system from deepening or pushing Northwards.
As the Low moves West, rainfall will be heavy on the weekend in interior TN, S.I. Karnataka and Kerala. Madurai region will get heavy precipitation this weekend.
Bangalore,overcast with intermittent rains on Saturday.

The direct effect of the low, may decrease along East coast after Tuesday 23rd. Chennai can see a decrease in rains from Wednesday,24th. ..
