Reasons Analysis by Vagarian T.Gokul (Pune) :

Leading edge of a moisture filled easterly surge approached Tamilnadu coast with winds decreasing around the edge.... probably leading to moisture convergence in the lower levels and at the same time the divergence associated with the upper level trough (east of trough axis ) probably aided in dynamic lifting by providing upper level ventilation to the column....and along with some frictional convergence as it neared the coast .... Broad understanding...


Large amounts of moisture flux over Southern bay of Bengal from south China sea
Easterly wind surge in the lower levels equatorward side of the Siberian high

Upper level divergence was seen to the east of trough axis
