Again I do not understand how this sset (a reader of Indianweatherman.com) is reporting 50% deficient. As per the latest data available Tamilnadu as a whole has received as much as 45cm rainfall for this season and it may be NORMAL[Positive side] rainfall. However there are few locations such as Dharmapuri, Krishnagiri, Vellore,Salem etc where the rainfall is DEFICIENT. Please refer Disaster Managment and Mitigation Department under Revenue Administration, Government of Tamilnadu site.(authentication required. What you give will lead to factual error.

Warm Air Advection near Chennai
Near 13 Degree latitude there is warm air advection. The Chennai DWR shows [161209/1200UTC] wind veering with height from lower-mid levels. This is may be warm air advection. This may lead to formation of clouds on and off Chennai coast. Lower level EAsterly or NE ly will bring them into Chennai. But lesser amount of precipitation
IMD has noted a RIDGE at 200 hPa level at 9 Degree North Latitude. It seems that the RIDGE had drifted further south to lay marked near Cape Comorin to day [17.12.2009 /0211 hrs IST]
One can expect some inclement weather, cloud formation over Kanyakumari both in Arabian Sea and Bay as the upper divergence above will induce lower level convergence at Cape Comorin sea area.
As expected the "Warm Air Advection" WAA gave light rainfall over on and off [Nellore to]Chennai coast some 1.5 hrs before
