The cloud is moving slowly in W-NWly direction. The high pressure ridge is preventing it to move in Northward direction. 

The SWly feeder to the circulation which passed through Salem and adjoining area experienced rainfall.

When there is cut off in circulation and possibly when there emerges another circulation near Chennai then probably Chennai may get rainfall.

The SW winds which have withdrawn from Indian main land is feeding moisture from Indian Ocean to the circulation and keeps it alive.

Bay circulation

As expected the SWM has come down to 14 Deg latitude in Arabian Sea and thence blow as NWly.  The Westerly, SWly winds in Comorin Sea makes circulation in Bay roughly about 440-550 km East /Se of Nagapattinam / Karaikal.  The UAC over Srilanka moved NNW and gave rainfall in southern parts of TN.  The circulation in south central Bay may bring rainfall to Choramandal coast i.e from Vedaranyam to Nellore in south coastal AP.  As pointed out by mentor this can also be considered as 'MONSOON LOW"[Trough].  SST and upper winds are favorable for strengthening of this circulation.  This may bring NEM to TN

[1] SWM is still prevalent in lower latitude.[i.e below 21 Deg North].  The less strengthen SWM winds at upper level form a UAC near Srilanka. 

[2] This UAC is pumping easterlies in to TN region.

[3] This may lead to a formation of low in SE bay.

[4] This is expected to give copious rainfall down south TN.

[5] Two anticyclones along 22 or 21 Deg North  latitude one in the west end  and other in the far east end of India is creeping. up
