Rain...Rain...... going away

 In the previous post the "condensation Trail" is depicted over  Chennai.  This implies moisture at 30,000 ft .  The warm air advection will bring rain tomorrow morning.
                              or
At least clouding will be there in Chennai tomorrow [22.08.2014] morning. 

This WMO [Severe Weather Information Center-SWIC] picture indicates TS over Tamil Nadu along 10 Deg Parallel too. 
Rapid formation will be there

As the SUN is marching towards south, the south Indian ocean is slowly getting warmth.  This means strength of SWM will be reducing .
